Most-missed South Carolina DMV rules

These are the numbers and rules that trip up new drivers most often on the real South Carolina knowledge test. Every fact below comes from our free South Carolina DMV practice test question bank, which has 180 questions across 8 topics.

Speed limits

The manual restricts golf cart use to secondary roads posted at 35 mph or below.
The manual requires drivers to obey the posted slower school zone limit when flashing lights are active or children are present.
The manual advises driving slower than the posted limit in residential and playground areas due to higher foot traffic risk.
The manual gives contextual guidance only; specific numeric speed limits are set by separate state statute or local ordinance.
South Carolina law sets the speed limit on interstate highways and freeways at 70 mph.
Multilane divided primary highways carry a speed limit of 60 mph.
In urban districts, the maximum speed limit is 30 mph unless a different limit is posted.
Manufactured/mobile homes may not be towed more than 10 mph below the posted limit and never faster than 55 mph.

Right of way

The manual instructs that no driver should assume automatic right-of-way and must evaluate each intersection's circumstances.
The manual states that at unmarked or uncontrolled bridge crossings, the first vehicle to reach the bridge gets the right-of-way.
The manual requires drivers to fully stop for a pedestrian using a white cane, recognizing a visual impairment.
The manual specifies drivers must yield to pedestrians in the intersection even when making a right turn on red.
The manual states bicyclists have the same legal rights, privileges, and responsibilities as motor vehicle drivers.
The manual notes drivers must yield right-of-way to cyclists on a bike path or bike lane.
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

The manual describes a Provisional Driver's License, available for a fee, as a limited relicensing option after some DUI/DUAC suspensions.
DUAC stands for Driving with an Unlawful Alcohol Concentration and is treated as its own offense alongside DUI in South Carolina.
The manual indicates refusal triggers at least a 6-month suspension, longer than the minimum suspension for testing positive at 0.02%.
Refusing implied-consent chemical testing is itself grounds for license suspension in South Carolina.
The standard adult DUI threshold is a BAC of 0.08% or higher, though 0.05% to 0.07% can still support impairment charges with other evidence.
Drivers under 21 are subject to zero tolerance and may not drive with a BAC of 0.02% or higher.
Administrative license revocation applies automatically at a BAC of 0.15% or higher for adults (0.02% for under-21 drivers).
DUI suspensions escalate by offense: 6 months for a first offense, 1 year for a second, and 4 years for a third within 5 years.
Refusing a BAC chemical test triggers an automatic 6-month (180-day) suspension for a first offense, with longer suspensions for a prior alcohol-related conviction or suspension within 10 years.

Signals and markings

The manual describes RCUT intersections as requiring the driver to cross the roadway before executing a U-turn onto a one-way roadway segment.
RCUTs are a distinct intersection type the manual highlights as less commonly documented, used to manage crossing and turning movements.
A flashing red signal functions like a stop sign, requiring drivers to come to a complete stop before proceeding when it is safe.
A solid yellow line on your side of the centerline indicates that passing is prohibited from that side of the road.
On a plain green light, a left-turning driver must yield to oncoming traffic and pedestrians before completing the turn.
A red flashing light is treated like a stop sign: stop, then yield to vehicles already in or entering the intersection.
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 is legally equivalent to a stop sign: the driver must come to a full stop before proceeding when clear.
At uncontrolled intersections, drivers must yield to vehicles that are already in the intersection.
A dashed yellow centerline indicates passing is generally allowed on that side when it is safe to do so and no other restriction applies.
A flashing yellow signal is a caution indicator meaning drivers may proceed but should do so carefully.
A flashing yellow signal means drivers may proceed but should slow down and use extra caution.
A flashing red signal is treated the same as a stop sign: come to a full stop, then proceed only when it is safe.
Headlights are legally required not just at night but any time weather conditions significantly reduce visibility.
A bike box lets cyclists position ahead of traffic; drivers must stop behind the box rather than within it.
A flashing red signal functions the same as a stop sign, requiring drivers to stop completely and then proceed only when it is safe.
A dashed yellow line means passing is allowed when there is a safe gap in oncoming traffic, unlike a solid yellow line.
A flashing yellow light warns drivers to slow down and proceed carefully, unlike a flashing red which requires a full stop.
A green arrow gives the protected right-of-way to proceed in that direction, though the driver must still yield to anyone already in the intersection.
A solid yellow line on your side of the center marking indicates passing is prohibited from that direction due to limited sight distance or other hazards.
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.
The manual instructs drivers not to change lanes once inside a roundabout.
A flashing yellow arrow permits the indicated turn but the driver must first yield to pedestrians and oncoming traffic.
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.

Safe driving

The manual requires drivers to stop and yield at a school crossing when signaled by a traffic patrol.
Endangering a highway worker with no injury results in a fine of $500 to $1,000, rising to as much as $5,000 if great bodily injury results.
Work zones are posted at least 10 mph under the normal maximum speed specifically to protect workers and should always be observed.
Advisory speed plates on curve warning signs indicate a safe reduced speed that drivers should slow to before entering the curve.
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.
Scanning further ahead gives drivers earlier warning of hazards, slowing traffic, or obstacles, allowing more time to react safely.
Since farm tractors typically travel around 25 mph, the speed differential requires extra caution and clearance when passing.
The manual requires dimming to low beams at least 300 feet before overtaking or following another vehicle.
Wet roads increase stopping distance, so drivers should slow down and add extra space to compensate for reduced traction.
The safe response to a skid is to ease off the gas and steer smoothly in the direction you want to travel, rather than braking hard or overcorrecting.
The Basic Speed Rule obligates drivers to reduce speed below the posted maximum in hazardous conditions.
Drivers must yield to emergency vehicles with active lights and siren by safely moving aside, not stopping in the travel lane.
A safe following distance gives a driver time to react and stop without a collision if traffic ahead slows or stops.
A 3 to 4 second following distance gives drivers enough time to react and brake safely under normal conditions.
Safe lane changes require checking mirrors, checking blind spots by looking over the shoulder, and signaling the intended move before moving over.
The manual stresses that no one should ever assume they automatically have the right of way, since other drivers may not yield as expected.
Sudden braking or sharp steering after a blowout can cause loss of control; easing off the gas while steering straight is safer.
The manual sets a specific cutoff allowing mopeds/scooters only on roads posted at 50 mph or lower.
The core safety reasoning is that other drivers may not yield as expected, so defensive caution prevents collisions.
Because SMV-marked vehicles like tractors move slowly and may turn into fields or driveways, safe practice is to keep distance and watch for signals before passing.
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.
Hydroplaning occurs when water accumulates faster than tire treads can disperse it, causing loss of contact with the road.
Since entering roundabout traffic must yield to vehicles already circulating, slowing down and watching for a safe gap is the correct approach.
The manual warns that leaving a large vehicle's wind-sheltered draft can expose your car to a sudden crosswind push, requiring a steering correction.
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

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.
A YIELD sign requires slowing down and stopping only if needed to give way to traffic or pedestrians on the intersecting road.
Warning signs alert drivers to hazards or changing conditions ahead, while regulatory signs like stop/yield signs impose legally required actions.
The triangular shape is uniquely reserved for Yield signs, telling drivers to slow and give way rather than come to a full stop.
A circular sign with a diagonal slash through it is used nationally to show that a prior restriction (like a speed limit) no longer applies.
Diamond-shaped yellow signs are standard warning signs alerting drivers to hazards ahead, such as curves, merges, or intersections.
Yellow warning signage in this context provides an advisory safe speed recommendation for hazards like curves, distinct from a legally binding limit.
The manual specifies reduced speed limits apply at locations marked with a School Crossing sign when children are present.
The eight-sided red STOP sign requires a complete stop at the marked line or intersection before proceeding when safe.
The octagonal red stop sign universally requires a full stop before the driver may proceed when safe.
Regulatory signs like stop and yield signs establish legally mandated driver actions, distinct from purely informational or warning signage.
The handbook instructs drivers at yield signs to slow down and yield to vehicles already in the intersection or approaching.
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

SC law allows registered golf carts on posted 35 mph or slower secondary roads only within roughly 4 miles of the registered address or gate.
The manual requires golf cart drivers to be 16 or older and hold a valid license, plus an SCDMV permit decal for the cart.
South Carolina requires an SCDMV-issued permit or registration decal for golf carts used on public roads.
The Act bans holding or supporting a mobile device, texting, emailing, or watching video while driving; hands-free earpieces are exempted.
The manual describes a higher fine for a second or subsequent offense along with points added to the driving record.
The Hands-Free Act exempts earpieces and wrist-worn devices used only for voice communication.
The Conditional License tier begins around age 15.5, requiring a skills test and a clean record period before full driving privileges.
The manual's time-of-day tiers require supervision for South Carolina teen drivers operating after midnight.
The manual mentions a free SCDMV practice-test smartphone app to help applicants prepare for the knowledge exam.
The manual states the knowledge test uses randomly selected questions based on its content, without listing an exact question count.
The manual notes a school-transport exception to the otherwise strict passenger limits for teen license tiers.
A second or subsequent failure-to-stop offense is a felony punishable by up to 10 years imprisonment and a 1-year license suspension.
Teens are eligible for a Beginner's Permit starting at age 15.
A Beginner's Permit must be held for more than 180 days before advancing to a Conditional License.
A Conditional License requires passing a vision test and a road test.
A Special Restricted License is available for ages 16 to under 17, requiring a vision and road test or an existing Conditional License.
Conditional and Special Restricted license holders may not carry more than two passengers under age 21 unless accompanied by a licensed driver at least 21 years old.
Unsupervised driving is allowed only from 6 a.m. to 6 p.m., extended to 8 p.m. during daylight saving time; later hours require adult supervision.
This waiver requires a $25 fee, a school/employer letter, and parental consent, and allows the teen to drive alone until midnight.
Accumulating six or more points before one year of licensure results in an automatic six-month license suspension.

Emergencies

The manual explicitly compares South Carolina's move-over law to the laws of most other states.
Drivers must move into a non-adjacent lane if it's safe to do so, or otherwise slow down significantly.
Violating the Move Over Law is a misdemeanor punishable by a fine of not less than $300 nor more than $500.
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 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.
The priority is to stop safely away from traffic, shut off the engine, and move away from the vehicle before dealing with the fire.
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.
Drivers must yield to emergency vehicles by pulling over to the right and stopping until the vehicle has passed.
The Move Over Law's amber-light tier covers highway maintenance vehicles, requiring drivers to move over or slow down similarly to emergency vehicles.
With a median under 20 feet wide, all lanes in both directions are required to stop for the school bus.
Drivers are required to stop at the scene of a crash involving injury or significant damage, provide information, and call for assistance if needed.
When a safe lane change isn't possible, drivers are generally expected to reduce speed and use caution passing the stopped vehicle.
Standard practice is to safely move to the right and stop, clearing the path for the emergency vehicle to pass.
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.
Drivers must move over a lane or slow down when passing any stationary vehicle with flashing lights on the roadside, not just law enforcement vehicles.
Drivers are expected to keep a substantial following distance after an emergency vehicle passes, rather than closing in immediately.
Moving vehicles safely out of the flow of traffic prevents further collisions before drivers exchange license and insurance information.
General emergency guidance for brake failure is to pump the brakes and use engine braking by downshifting to slow down safely.
Pumping the brakes can rebuild some pressure, and downshifting uses engine braking to help slow the vehicle safely before using the parking brake carefully.
The manual instructs drivers to pull to the right edge and remain stopped until the emergency vehicle passes.
Standard practice for emergency vehicle right-of-way is to safely move to the right side of the road and stop to let it pass.
23 V.S.A. § 1050(b) requires moving over a full lane if safe, or slowing to a reasonable speed if the driver must remain in the adjacent lane.
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.
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.
