Most-missed Mississippi DMV rules

These are the numbers and rules that trip up new drivers most often on the real Mississippi knowledge test. Every fact below comes from our free Mississippi DMV practice test question bank, which has 180 questions across 9 topics.

Speed limits

The manual's legal speeds table lists 70 mph as the maximum for interstates under ideal conditions.
The manual sets the school zone maximum speed at 15 mph for any vehicle.
The manual specifies a 45 mph maximum for school buses on regular routes carrying children, versus a higher limit while on the interstate.
The manual's speed table lists 55 mph as the maximum for two-lane state and U.S. highways.
The manual lists a 40 mph minimum speed alongside the 65 mph maximum for four-lane state and U.S. highways.
The manual repeatedly cautions that posted limits assume ideal conditions and must be reduced for hazards like curves, congestion, or poor visibility.

Right of way

Mississippi's school bus law has a documented exception: on a divided highway of 4+ lanes with a physical median, only same-direction traffic must stop for the bus.
Mississippi requires drivers at uncontrolled intersections or exiting a driveway/private entrance to yield to traffic already on the through roadway, even without a posted sign.
When two vehicles arrive simultaneously at a four-way stop, the vehicle to the right is given the right-of-way.
The manual notes that the vehicle going straight has the right-of-way over a vehicle turning across its path when both stop at the same time.
Mississippi's rules state pedestrians in a crosswalk, marked or unmarked, always have the right-of-way.
Entering traffic must yield to vehicles already in the roundabout, and travel within the roundabout proceeds counterclockwise.
General safe-driving practice, reflected in most state manuals including Mississippi's, places responsibility on the merging driver to match speed and merge safely while highway traffic assists when it can.
Do not cut through or break up a funeral procession. Slow down, be patient, and let it pass. Cutting between the vehicles is unsafe and often illegal.
At an uncontrolled intersection, slow down and yield to any car already in the intersection or approaching from your right.
A left-turning vehicle must yield to oncoming through traffic and to pedestrians. Only turn when the gap is safe.
When entering a roundabout, yield to traffic already circulating and travel counterclockwise. Exit at your street; do not stop in the middle of the circle.
At a T-intersection, traffic on the road that ends must yield to traffic on the through road that continues.
A round green light allows a left turn but does not give you the right of way. Pull into the intersection, yield to oncoming through traffic and pedestrians, then turn when there is a safe gap.

Alcohol and DUI

Mississippi sets the adult DUI threshold at 0.08% BAC or higher for drivers 21 and older.
Zero Tolerance applies to drivers under 21 with a BAC of 0.02% or higher but less than 0.08%; at 0.08% or above, it becomes a regular adult DUI charge instead.
A first DUI offense is a misdemeanor carrying a fine, up to 48 hours of jail time, and a period of license suspension.
A third DUI within five years is charged as a felony in Mississippi, with much higher fines and a multi-year custody sentence compared to lower-tier offenses.

Signals and markings

A broken yellow line on your side permits passing when safe, while a solid yellow line on your side prohibits passing, a standard center-line marking convention drivers must recognize.
A flashing red signal functions like a stop sign, requiring drivers to come to a complete stop before proceeding when it is safe.
A flashing yellow signal is a caution indicator, telling drivers to slow down and proceed carefully rather than stop.
A dashed yellow line means passing is allowed when there is a safe gap in oncoming traffic, unlike a solid yellow line.
A law enforcement officer's directions override traffic signals, so drivers must obey the officer even if it means stopping on a green light.
A green arrow grants a protected right of way to complete that turn without yielding to opposing traffic.
The manual requires dimming high beams for oncoming traffic to avoid blinding other drivers.
A steady red signal requires a full stop; any right turn on red is only allowed after stopping and when safe and not prohibited by signage.
A steady yellow light warns that the right of way is ending and the signal is about to turn red.
A yellow light signals that the light is about to change to red, and drivers should stop if they can do so safely rather than accelerate through it.
A flashing yellow signal is a caution indicator meaning drivers may proceed but should do so carefully.
Headlights are legally required not just at night but any time weather conditions significantly reduce visibility.
A flashing red signal is legally equivalent to a stop sign: the driver must come to a full stop before proceeding when clear.
A steady yellow light warns the signal is about to turn red; drivers should stop safely if possible or proceed with caution if too close to stop.
Broken white lines between same-direction lanes indicate that changing lanes is allowed when it can be done safely.
A red flashing light is treated like a stop sign: stop, then yield to vehicles already in or entering the intersection.
Double solid yellow lines indicate that passing is not permitted from either direction on that stretch of road.
A flashing yellow light means slow down, look, and proceed carefully. It does NOT require a full stop the way a red light or STOP sign does.
A flashing hand or countdown means do NOT start crossing. If you are already in the crosswalk, keep going and finish crossing safely.
A steady DON'T WALK hand prohibits starting to cross. Only a WALK signal or walking-person symbol allows you to begin crossing.
Always signal continuously through a turn or lane change even when you see no other cars, because pedestrians or cyclists may be near. Cancel the signal after you finish.
A green downward arrow means the lane is open for you to use. A red X above the lane means it is closed and you may not drive in it.
Double solid yellow lines separate opposing directions and prohibit passing. You may only cross them for a permitted left turn or a legal U-turn into an intersection or driveway.
A broken yellow line on your side of the lane allows passing when it is safe. The solid line on the opposite side means that direction may not pass.
White lines separate lanes going the same direction. A solid white line means stay in your lane and avoid changing lanes, while a broken white line lets you change lanes when safe.
A two-way center left-turn lane is only for preparing to turn left or merging into traffic. You may not use it to drive straight through or to pass.

Parking

Standard parking rules, reflected in Mississippi's manual, prohibit parking so close to a hydrant or intersection that it obstructs access or visibility.
Because cyclists have full road rights and must be given clearance, drivers should check for approaching traffic and cyclists before opening a door into the lane.

Safe driving

Mississippi has a specific anti-squatting statute making it illegal to raise a vehicle's front fender 4 or more inches higher than the rear fender, a rule aimed at lifted/modified trucks.
Mississippi's manual specifies a minimum 3-foot passing clearance for bicycles, which are legally classified as vehicles with full road rights.
Mississippi requires two separate systems, a foot brake and a parking brake, each specified to stop the vehicle within a set distance when traveling at 20 mph.
The manual specifies the horn must be audible from about 200 feet away.
The manual states headlights must illuminate a person 500 feet ahead and taillights must be visible 500 feet behind.
Since posted limits assume ideal conditions, drivers must adjust following distance and speed for hazards such as rain, fog, or low visibility.
Cyclists are legally vehicles, so standard passing restrictions like no-passing zones still apply, in addition to observing the minimum clearance distance.
Mississippi's seat belt law requires every operator, every passenger, and every child under 18 (regardless of seat) to wear a properly fastened seat belt.
Mississippi bans texting while driving for holders of intermediate licenses, temporary learning permits, or temporary driving permits.
Safe driving practice calls for maintaining enough distance behind the vehicle ahead to react and stop safely if it brakes suddenly.
Sudden braking or sharp steering after a blowout can cause loss of control; easing off the gas while steering straight is safer.
Because posted speed limits assume ideal conditions, the handbook advises reducing speed in rain and other hazardous conditions.
The manual requires headlights to be on whenever visibility is under 1,000 feet.
Rural highways through unfenced farm and ranch land require extra alertness for livestock and wildlife crossing the road.
Work zones require reduced speed and heightened alertness because of workers, equipment, and changing lane patterns.
Handbooks generally recommend a multi-second following distance that should be increased in bad weather, at higher speeds, or in heavy traffic.
Drivers must stop for a school bus with flashing red lights and remain stopped until the lights stop flashing, protecting children crossing.
A safe following distance gives a driver time to react and stop without a collision if traffic ahead slows or stops.
Fatigue slows reaction time and judgment similarly to impairment, and can lead to microsleeps that cause the driver to lose control.
A time based following distance, counting seconds behind the vehicle ahead, adjusts naturally for speed and is the standard safe driving practice.
Posted speed limits are for ideal conditions; drivers should reduce speed further and increase following distance in poor weather like heavy rain or fog.
An owner cited by a stop-arm camera faces monetary penalties instead of points: $250 for a first violation, rising to $300 for a third within 18 months.
Drivers must yield to emergency vehicles with active lights and siren by safely moving aside, not stopping in the travel lane.
Drivers are generally taught to keep a multi-second time gap behind the vehicle ahead, increasing it in rain, snow, or fog for adequate stopping distance.
General right-of-way practice, reflected in the manual, is that the first vehicle to arrive and stop proceeds first; simultaneous arrivals yield to the right.
A several-second following distance, often cited as at least 3 seconds under normal conditions, provides reaction time to avoid rear-end collisions.
A driver overtaking a bicyclist may not turn right unless it can be completed at a safe distance from the cyclist and at a reasonable, proper speed.
Children under 7 must use a child restraint system meeting 49 CFR 571.213 standards unless they are 57 inches or taller.
The Basic Speed Rule obligates drivers to reduce speed below the posted maximum in hazardous conditions.
The manual stresses that no one should ever assume they automatically have the right of way, since other drivers may not yield as expected.
Passengers under 2 years old must specifically be secured in a rear-facing child restraint system.
With a tailgater, open up more space in front of you so you can brake gradually instead of suddenly. Do not brake to retaliate and do not race away.
Strong crosswinds can push your car out of its lane. Hold the wheel firmly with both hands, slow down, and be ready for sudden gusts.
Do not engage. Avoid eye contact, do not brake in retaliation, let them pass, and leave a safe distance between you and that car.
Horses and livestock spook easily. Slow down, do not honk or rev your engine, and pass very slowly with plenty of room so you do not startle them.
When you see a hazard developing ahead, cover the brake and plan an escape route so you can react faster if you have to stop.
In a skid, ease off the gas or brake and steer gently in the direction you want the front of the car to go. Slamming the brakes makes the skid worse.

Road signs

Diamond-shaped yellow signs are standard warning signs alerting drivers to hazards ahead, such as curves, merges, or intersections.
The octagon shape combined with red color is reserved exclusively for stop signs in the national uniform sign system Mississippi follows.
STOP (R1-1): full stop at the line or crosswalk even when empty; yield, then proceed.
YIELD (R1-2): give up the right-of-way; slow and be ready to stop.
DO NOT ENTER (R5-1): entry prohibited; common at freeway off-ramps and one-way streets.
WRONG WAY (R5-1a): you have entered opposing traffic. Pull over safely and turn around when possible.
ONE WAY (R6-1): all traffic flows in the arrow's direction.
NO U-TURN (R3-4): no U-turns at this location. This is not a no-left-turn sign (a different arrow shape) or a no-passing sign (a different shape and color entirely).
NO LEFT TURN (R3-2). A red circle-and-slash always bans the pictured movement.
NO RIGHT TURN (R3-1): no right turns, including on red. Going straight is still fine since the sign only bans the right-turn movement; parking is unrelated to this sign.
White/black = regulatory. Speed Limit is the legal max in ideal conditions; drive slower when conditions are bad (Basic Speed Law).
KEEP RIGHT (R4-7): a median or obstruction is ahead; keep to its right.
The crossbuck (R15-1) stands at the tracks and legally works like a YIELD sign: slow, look both ways, be ready to stop.
Advance warning (W10-1): tracks ahead. Slow down, look, and listen.
School (S1-1): school zone or crossing. Slow down and watch for children; obey the posted reduced school-zone speed limit, which varies by state.
Pedestrian crossing (W11-2): crossing ahead; slow and be ready to stop.
Signal ahead (W3-3): an intersection signal is coming, useful when it hides behind a curve.
Stop ahead (W3-1): a stop sign is coming (often obscured); start slowing now.
Merge (W4-1): traffic joins ahead. Adjust speed and position to let them in safely.
Lane ends (W4-2): merge early; zipper-merge when traffic is heavy.
Two-way traffic (W6-3): you are leaving a one-way road; keep right.
Divided highway begins (W6-1): directions separate around a median; always keep right of it.
Slippery when wet (W8-5): slickest in fresh rain. Slow down, keep distance, steer smoothly.
Curve (W1-2): slow BEFORE the curve; do not brake in the middle of it.
Turn (W1-1): sharper than a curve; slow down hard, follow the advisory plaque.
Winding road (W1-5): consecutive curves; hold a steady lower speed throughout.
Crossroad (W2-1): an intersection ahead with traffic entering from both sides. Hospital signs are blue with an H.
NO PASSING ZONE (W14-3): unique pennant shape, posted on the LEFT side, marks where passing becomes illegal.
Diamond-shaped yellow signs are warning signs, alerting drivers to hazards or changes in road conditions ahead.
White rectangular signs with black lettering are the standard shape and color used for regulatory information like speed limits or turn rules.
The eight-sided octagon shape is reserved exclusively for Stop signs so it can be recognized even from behind or in poor visibility.
Warning signs alert drivers to hazards or changing conditions ahead, while regulatory signs like stop/yield signs impose legally required actions.
The manual specifically calls out School Crossing signs with children present as requiring reduced speed.
The railroad advance warning sign is round with an X and R R symbol, one of the only circular warning signs used on US roads.
Orange is the standard color used for temporary construction and work zone signs, regardless of the specific shape used.
The triangular shape is uniquely reserved for Yield signs, telling drivers to slow and give way rather than come to a full stop.
School zone and school crossing signs use a distinctive fluorescent yellow-green pentagon shape to stand out to drivers.
A downward-pointing triangle is the standard yield sign, instructing drivers to slow and give right of way to conflicting traffic.
A yield sign requires slowing and yielding to conflicting traffic, stopping only if needed to avoid a hazard.
The handbook instructs drivers at yield signs to slow down and yield to vehicles already in the intersection or approaching.
Drivers must stop at the marked line or crosswalk, or at the edge of the intersection if there is no marking, before proceeding.
The octagon shape combined with red coloring is reserved exclusively for stop signs, requiring a full stop.
Diamond-shaped yellow signs are the standard shape/color combination used for general warning signs about upcoming hazards or conditions.
Warning signs (typically yellow, diamond shaped) inform drivers of hazards ahead like curves or crossings, distinct from regulatory signs that state legal requirements.
Yellow diamond signs are standard warning signs alerting drivers to hazards or changing road conditions ahead.
The manual specifies reduced speed limits apply at locations marked with a School Crossing sign when children are present.
Diamond-shaped yellow signs are warning signs, alerting drivers to hazards like curves, merges, or crossings ahead.
The yellow pennant-shaped sign marks the start of a no-passing zone. It usually appears along with a solid yellow line on the pavement.
A yellow diamond-shaped sign is a WARNING sign, alerting you to a hazard or change ahead such as a curve, intersection, or school, so you slow down.
A white rectangular sign with black lettering is a REGULATORY sign stating a law you must obey, such as speed or direction of travel.
An orange sign marks a construction or roadwork zone. Slow down and watch for workers and shifting lanes.
A blue sign points to driver services such as gas stations, food, lodging, or hospitals.
A green sign is a GUIDE sign, showing directions, distances, and the names of exits or places.
A red circle with a slash means the action shown is PROHIBITED, such as no turn or no U-turn at that spot.

Laws and paperwork

The manual classifies bicycles as vehicles with full road rights, and cyclists may legally ride two abreast.
Mississippi does not legally mandate a rearview mirror, though it is recommended; a side mirror is required only when the body obstructs rear visibility.
The current manual already notes that starting July 1, 2027, applicants will need to complete a certified Driver's Education and Training program before receiving an original license.
Mississippi's littering law explicitly makes both the operator and the owner of the vehicle liable, even if the owner was not the one driving.
Mississippi issues a distinct vertical-format license marked 'UNDER 21 UNTIL' or 'UNDER 18 UNTIL' a specific date for younger license holders.
Mississippi's regular learner's permit can be obtained at age 15 with proof of school enrollment, and it is valid for 2 years.
The Mississippi learner's permit fee is $7.00.
A Mississippi learner's permit must be held for a minimum of 12 months before a Class R license can be obtained, except applicants already 17 or older are exempt.
No electronic devices are permitted during the exam; violators face immediate test cancellation and a 6-month ban from retesting.
Mississippi drivers may renew their license up to six months prior to its expiration date.
If expired or suspended for more than 60 months (5 years), the driver must retake the written knowledge test and apply for a new license.
Applicants over age 17 face no waiting period, unlike younger teen applicants who must hold the permit 12 months.
The Mississippi Driver Service Bureau can be reached at 601-987-1224 for driver licensing questions.

Emergencies

Drivers must yield to emergency vehicles by moving to the right shoulder; on a divided highway of 4+ lanes, they should move over a lane away if it is safe to do so.
On divided highways of 4+ lanes, drivers should move over a lane away from a stopped emergency vehicle when it can be done safely.
Standard emergency procedure is to move fully onto the shoulder, activate hazard lights, and, if safe, move away from the travel lanes rather than stopping in traffic or continuing to drive on damaged equipment.
When a safe lane change isn't possible, drivers are generally expected to reduce speed and use caution passing the stopped vehicle.
Moving vehicles safely out of the flow of traffic prevents further collisions before drivers exchange license and insurance information.
Drivers may not park their vehicle within the block where an emergency vehicle has stopped to respond to an incident.
Drivers must yield to emergency vehicles by moving to the right edge of the roadway, staying clear of intersections, until it passes.
Drivers must yield right-of-way, pull as far right as possible, stop, and remain stopped until the emergency vehicle has passed.
Standard guidance for hydroplaning is to ease off the gas and avoid sudden braking or steering, letting the tires regain contact with the road.
Drivers are required to stop at the scene of a crash involving injury or significant damage, provide information, and call for assistance if needed.
Rapid brake lights or hazard signals ahead indicate a potential emergency or obstruction, so drivers should slow down and prepare to react safely.
The manual specifies the stop requirement does not apply when a physical median or other barrier separates the two roadways, unlike a simple painted line.
Drivers must yield to emergency vehicles by pulling to the right and stopping, while making sure not to block the intersection.
Drivers are expected to keep a substantial following distance after an emergency vehicle passes, rather than closing in immediately.
Drivers must yield to emergency vehicles by pulling over to the right side of the road, clear of intersections, and stopping until the vehicle passes.
Standard right-of-way and safe-driving practice requires yielding to emergency vehicles by pulling right and stopping until they pass.
Move Over laws require drivers to move over or slow down for any stopped vehicle with warning lights activated, to protect people near the roadway.
On typical two-lane roads, traffic in both directions must stop for a loading school bus; the opposite-direction exception applies only on wider divided highways.
The Move Over Law has escalating consequences: a basic violation carries a modest fine and point penalty, a violation causing a crash carries a higher fine, and one causing death or serious injury carries the harshest penalty.
Standard practice is to safely move to the right and stop, clearing the path for the emergency vehicle to pass.
Per N.J.S.A. 39:4-81, a malfunctioning or dark traffic signal must be treated as an all-way stop.
The manual notes you only have right of way if the other vehicle isn't already in the intersection, meaning a vehicle already there should be allowed to clear first.
When changing lanes is not safe, the Move Over Law still expects drivers to reduce speed and use caution passing the stopped vehicle.
If your car catches fire or smells like burning, pull over, shut off the engine, and get everyone away. Do not open the hot hood, since the rush of air will make the fire flare up.
If the gas pedal sticks, shift to Neutral to cut the power, then brake and steer to the shoulder. Only turn off the engine after you have fully stopped, so you do not lose power steering.

Signs

Sign shape and color carry meaning before you even read the words. A red octagon always means stop, a red-bordered triangle pointing down means yield, and yellow diamonds warn of a hazard ahead. For every sign image used in our practice test, with the exact meaning and explanation, see the full road sign glossary.
