1. A Missouri driver is convicted a second time within five years of failing to stop for a school bus. How long is the suspension?
- 30 days
- 180 days
- One year
- 90 days
Show answer
90 days. Failing to stop for a school bus that is loading or unloading students adds five points. A first offense brings a court ordered suspension of 90 days or as the court designates, a second offense within five years brings 90 days, and a third or later offense within five years brings 180 days. So 180 days is for the third offense. Thirty days and one year are not in this rule.
2. At what age can a Missouri driver get an instruction permit, the first step of the graduated driver license program?
- 16
- 14
- 15
- 17
Show answer
15. The instruction permit is the first step in Missouri's Graduated Driver License program, and the eligible age is 15. It allows practice driving with a qualified adult. Anyone under 21 is issued a permit that identifies them as a minor. The intermediate license, the second step, has an eligible age of 16, and it requires 40 hours of driving instruction including at least 10 hours at night.
3. Which action matches a flashing yellow traffic signal rather than a flashing red signal?
- Slow down and proceed carefully
- Stop as though facing a stop sign
- Wait for a police officer before moving
- Treat the intersection as closed to all traffic
Show answer
Slow down and proceed carefully. Missouri distinguishes the two flashing signals: yellow means slow down and proceed with caution, while red means the same thing as a stop sign. That makes a full stop the wrong automatic response to yellow, although stopping may still be sensible if traffic or pedestrians require it. No officer is needed for ordinary operation, and the intersection is not closed. Remember the color pairing at the approach: flashing yellow is caution, flashing red is stop, then apply the rest of the roadway conditions.
4. What should a driver try first when the brake pedal suddenly sinks to the floor?
- Turn off the ignition while still moving
- Pump the brake pedal fast and hard several times
- Apply the parking brake as hard as possible at once
- Accelerate to reach a repair shop quickly
Show answer
Pump the brake pedal fast and hard several times. For a sudden brake-pedal failure, Missouri advises pumping the pedal fast and hard several times first. If that does not work, use the emergency or parking brake gradually, shift to a low gear, and look for a place to stop off the road. Turning off the ignition while moving can create another loss of control, and a sudden hard parking-brake application can cause a skid. The sequence matters: pump, apply backup braking gradually, select low gear, and seek a safe stopping place.
5. Why does the Missouri guide say to slow down after one deer crosses in front of you?
- Deer always cross back the same way
- One deer means the road is clear behind it
- Deer are attracted to headlights
- Deer seldom travel alone, so more are likely to follow
Show answer
Deer seldom travel alone, so more are likely to follow. Missouri's deer crash precautions include being especially alert in areas marked with deer crossing signs and remembering that deer seldom travel alone; if you see one deer crossing, chances are others are near. The first deer often draws your eyes while the second steps out. Slow down, scan both shoulders, and be ready to brake in a straight line rather than swerving into traffic or off the road.
6. When approaching a stationary emergency vehicle on a Missouri road with at least four lanes, what lane change is required when safe?
- Move toward the stationary vehicle's lane
- Move into a lane not adjacent to the stationary vehicle
- Change into the oncoming traffic lane
- Remain beside the vehicle at the same speed
Show answer
Move into a lane not adjacent to the stationary vehicle. On a roadway with at least four lanes and at least two lanes moving in the approaching driver's direction, the driver should make a lane change into a lane not adjacent to the stationary emergency vehicle when that can be done safely. Remaining beside it leaves no buffer, and moving toward it increases exposure. The oncoming lane is not a safe or lawful substitute. The condition matters: change away when possible, then use the reduced speed and caution rule when a lane change cannot be made safely.
7. When driving in Missouri, what must a driver carry as evidence of driving authority?
- Only the driver examination record
- A vehicle title instead of a license
- A signed note from an adult passenger
- The driver license or permit
Show answer
The driver license or permit. A driver must carry the driver license or permit while driving and present it when a law enforcement officer asks to see it. The examination record alone is not the same document and cannot replace the issued credential. A vehicle title proves an ownership matter, while an adult passenger's note has no licensing authority. A simple cue is document in hand: carry the issued license or permit, not merely proof that a test was completed or that the vehicle belongs to someone.
8. When driving beside a motorcycle, which practice is required?
- Use part of the motorcycle's lane to pass closely
- Follow within one car length
- Do not share a lane with the motorcycle
- Assume the motorcycle will always yield
Show answer
Do not share a lane with the motorcycle. A motorcycle needs the full lane for stability, visibility, and room to respond to road conditions. Do not place your vehicle beside it in the same lane, even if the motorcycle appears small enough to leave space. Passing closely can startle the rider and leaves no margin for a pothole, wind gust, or sudden maneuver. Scan mirrors before changing position, wait for a clear opportunity, and give the motorcycle a complete lane when passing. The full-lane rule is the key cue.
9. After an administrative BAC suspension notice in Missouri, when does the suspension or revocation generally begin?
- After 15 days
- At the instant of the traffic stop
- After 30 days
- Only after a criminal trial
Show answer
After 15 days. The administrative notice tells the driver that the license will be suspended or revoked after 15 days. That notice may include a 15 day driving permit when the officer indicates it, and the driver may request a hearing or, if eligible, an immediate restricted privilege. The instant stop choice ignores the stated waiting period, while the criminal trial choice confuses an administrative action with a court case. Mark the number 15 as the transition from notice to the administrative license action.
10. At a Missouri J turn intersection, what path does a driver use to continue toward the opposite direction?
- Reverse through the intersection and reenter
- Cross directly through opposing traffic
- Turn left across the median immediately
- Turn right, merge into the far left lane, then turn left
Show answer
Turn right, merge into the far left lane, then turn left. A J turn replaces a direct crossing movement with a right turn in the same direction as traffic, a merge into the far left lane, and a left turn toward the intended destination. The direct crossing choice defeats the design's purpose of avoiding fast moving opposing lanes. Turning left immediately or reversing are not parts of the maneuver. Picture the shape as a right entry followed by a wide loop and a later left turn, with each movement made in the direction permitted by the roadway.
11. How far may a vehicle travel in a Missouri two way left turn lane?
- No more than 100 feet
- No more than 250 feet
- No more than 500 feet
- Any distance if the lane is empty
Show answer
No more than 500 feet. The center two way left turn lane is for preparing to slow or stop before a left turn, not for ordinary travel. The guide limits a vehicle from traveling in it more than 500 feet. The smaller distances are not the stated limit, while the unlimited option ignores the lane's turning purpose. A driver should enter it only for the approaching left turn, make the maneuver promptly, and avoid using the center lane as a substitute for a through lane.
12. How should a driver respond to a steady yellow traffic light?
- Speed up whenever the light has just changed
- Stop in the middle of the intersection
- Stop unless already in the intersection or unable to stop safely
- Continue without checking for the coming red signal
Show answer
Stop unless already in the intersection or unable to stop safely. A steady yellow warns that the signal is changing from green to red. Missouri says to stop unless the vehicle is already within the intersection or is so close that stopping before entry cannot be done safely. The risky alternative is accelerating simply to beat the red, while an abrupt stop in the intersection creates a separate hazard. Check distance and speed, brake smoothly when there is room, and clear the intersection when stopping would be unsafe.
13. What is the paved area on the inside of a Missouri roundabout called, and who is it for?
- A truck apron, for the rear wheels of large trucks that need more space
- A pedestrian refuge
- A bicycle lane
- A parking area for disabled vehicles
Show answer
A truck apron, for the rear wheels of large trucks that need more space. Large trucks need more space when driving in a roundabout, and the truck apron, also called off-tracking space, is the paved area on the inside of the roundabout for the rear wheels of a large truck to ride over. Cars should stay out of it and never drive beside a truck in the circle, since the trailer may sweep across the lane. It is not a bike lane, a pedestrian refuge or a parking spot.
14. Which paperwork failure is listed among the reasons Missouri can take away a driver license?
- Failing to wash the license plates
- Failing to carry the owner's manual
- Failing to keep a paper map
- Failing to file an accident report when required
Show answer
Failing to file an accident report when required. The guide's list of reasons for losing a license includes failing to file an accident report, giving false information when applying for a license, failing to settle a court judgment for damages from a crash, and failing to keep insurance. An accident report is required after crashes that meet the state thresholds, and skipping it is treated as seriously as the crash itself. The other choices are not legal duties.
15. What restriction does a pennant-shaped sign identify?
- A scenic overlook where parking is encouraged
- A no-passing zone
- A railroad crossing ahead
- A school zone with flashing lights
Show answer
A no-passing zone. The pennant shape is Missouri's visual clue for a no-passing zone. It marks a section where passing is unsafe, commonly because the road is on a hill or curve and the driver cannot see far enough ahead. A scenic area, school zone, and railroad crossing use different signs and rules. When the pennant appears, keep your vehicle in its lane, hold a safe speed, and wait until the restriction has ended before attempting a pass. Shape recognition helps the driver react before reaching the hazard.
16. What option can the administrative alcohol notice provide to an eligible Missouri driver?
- A hearing request or an immediate 90-day Restricted Driving Privilege request
- A waiver of every court requirement
- A permanent exemption from alcohol laws
- An automatic license renewal without review
Show answer
A hearing request or an immediate 90-day Restricted Driving Privilege request. The notice can allow the driver to request a hearing or, if eligible, request an immediate 90-day Restricted Driving Privilege. Those are review or limited-driving pathways, not an automatic renewal and not a permanent exemption. The guide also explains that a hearing can preserve legal driving until 15 days after the decision is mailed. Read the notice carefully because eligibility and deadlines control which option is available.
17. Which event causes failure of the Missouri driving test even apart from the point total?
- Violating a traffic law during the test
- Driving below the limit while conditions require it
- Adjusting the mirror before moving
- Checking traffic before a turn
Show answer
Violating a traffic law during the test. A traffic-law violation is an independent reason for failing the Missouri skills test. It is listed alongside a fault crash, hitting a pedestrian, dangerously driving, or refusing the examiner’s direction. Mirror adjustment and traffic checks are normal preparation, while a lower speed can be appropriate when conditions require it. Keep the vehicle controlled, obey every sign and signal, and remember that a low point total cannot rescue an illegal maneuver.
18. What should a driver do when approaching the five-sided school crossing sign?
- Maintain speed because the sign applies only to school buses
- Slow down and watch for children crossing the road
- Turn around before entering the school zone
- Stop in the lane until a crossing guard waves through every car
Show answer
Slow down and watch for children crossing the road. The pentagonal school crossing sign warns that children may be crossing. Drivers should slow down and watch carefully for them. It does not apply only to school buses, and it does not require stopping in the travel lane when no crossing movement calls for a stop. A U-turn is also unrelated to the warning. The child figures and five-sided shape provide an early visual cue, but the necessary response depends on what is actually happening near the crossing. Scan the sidewalk, crosswalk, and road edges before continuing through the school area.
19. What does the STOP AHEAD warning sign mean?
- The current road has ended and requires a U-turn
- A stop sign is ahead, so prepare to stop
- Stopping is prohibited beyond the sign
- The driver has priority over all crossing traffic
Show answer
A stop sign is ahead, so prepare to stop. STOP AHEAD is an advance warning that a stop sign is coming on the road being traveled. The driver should prepare by adjusting speed and looking for the required stopping point. It does not prohibit stopping, end the roadway, authorize a U-turn, or give priority over crossing traffic. The small stop sign pictured on the yellow warning sign distinguishes an upcoming control from the actual stop sign. Anticipating the stop helps prevent a rushed braking maneuver and leaves time to check the intersection after coming to a complete stop.
20. Which restraint may be used for a Missouri child who is at least eight years old, at least 80 pounds, or taller than 4 feet 9 inches?
- No restraint because the child is beyond the law's coverage
- Only a rear-facing infant restraint
- A vehicle safety belt or booster seat appropriate for the child
- A child restraint system only, with no booster option
Show answer
A vehicle safety belt or booster seat appropriate for the child. Missouri places a child in the older-child classification when the child is at least eight years old, at least 80 pounds, or taller than 4 feet 9 inches. That classification calls for a vehicle safety belt or an appropriate booster seat. The rule does not eliminate restraint use, and it does not limit the child to an infant seat or to a child restraint system alone. The word or is important: meeting any one of the listed thresholds is enough for this category. Confirm that the belt fits properly and that a booster remains suitable for the individual child.
