1. You see brake lights several vehicles ahead of you in your lane. What is the best first step?
Show answer
Answer C: Ease off the gas and cover the brake pedal
Reacting to the trouble several vehicles ahead, rather than waiting for the car in front, cuts your reaction time and warns the driver behind you.

2. What blood alcohol content makes driving illegal in Missouri for an adult in a car and for a commercial driver?
Show answer
Answer A: .08 percent in a car and .04 percent in a commercial vehicle
Missouri sets .08 percent for drivers aged 21 and over, .04 percent for commercial vehicle drivers, and .02 percent for drivers under 21.
-
3. How should the mirrors be set before setting off?
Show answer
Answer B: So that each mirror shows the lane behind and part of the lane beside
Mirrors aimed too far inward show mostly the rider, wasting the view that is meant to cover the traffic behind and to the side.
-
4. You want to turn right at a steady red light and no sign prohibits the turn. What is required?
Show answer
Answer B: Come to a complete stop, then yield to traffic and pedestrians before turning
A right turn on a steady red is permitted only after a complete stop and only after yielding to cross traffic and to pedestrians, and a posted sign can prohibit it entirely.
-
5. You need to reverse direction on a busy street. Which choice is usually safest?
Show answer
Answer D: Driving around the block and using the intersections instead
Going around the block uses normal turns at controlled intersections instead of stopping across live traffic lanes.
-
6. Traffic is backed up beyond a railroad crossing. When may you start across the tracks?
Show answer
Answer B: Only when there is room for your whole vehicle on the far side
Never enter a crossing you cannot clear; a vehicle stopped on the tracks in a queue has nowhere to go if the signals start.
-
7. Why is parking next to a fire hydrant or in a marked fire lane prohibited?
Show answer
Answer D: It would delay firefighters who need immediate access to the hydrant or the building
Fire hydrants and fire lanes must remain clear at all times so emergency crews can connect hoses and reach a building without delay.
-
8. A driver in the left lane of a freeway realizes only when level with this sign that the ramp beside it is the one they need. What is the correct action?
Show answer
Answer A: Carry on to the next interchange and turn back from there
There is no safe way back to a ramp once it has been reached from the wrong lane, so the driver keeps going to the next interchange, where the ramps are built for that movement.
-
9. This sign is still standing late at night, and nobody is working. What should the driver assume?
Show answer
Answer B: The layout may still be altered, so the same care and reduced speed apply
Narrowed lanes, shifted alignments, dropped pavement edges and parked equipment remain overnight, so the hazard does not end when the crew goes home.
-
10. You are driving down a parking aisle and reach the main lane that runs along the front of the store. What is the usual rule?
Show answer
Answer C: The main through lane has the right of way over the vehicles leaving the aisles
In a parking lot the wide lane that runs across the ends of the aisles works like a through road, and drivers leaving an aisle yield to it.
-
11. Traffic is heavy and a truck is stopped in the lane on your right. How do you keep an out?
Show answer
Answer B: Keep space open ahead of you and avoid being boxed in on both sides at once
Being hemmed in on both sides with no gap ahead removes every option, so keep at least one direction open.
-
12. A deer has just crossed in front of you on a stretch signed for animal crossings. What is the best assumption?
Show answer
Answer B: More animals are likely to follow the first one
Deer travel in groups, so one animal crossing usually means others are about to follow, and a driver should slow and keep scanning both shoulders.
-
13. A highway lane is marked with a large white diamond and signed as a high-occupancy vehicle lane. Who may use it?
Show answer
Answer B: Only vehicles carrying at least the number of occupants shown on the sign, during the posted hours
The diamond marking identifies a preferential lane whose occupancy requirement and hours of operation are stated on the accompanying signs.
-
14. A driver stopped on suspicion of impaired driving refuses to take a chemical test. What happens?
Show answer
Answer D: A license penalty follows for the refusal itself
Under implied consent, holding a license means agreeing to testing, so a refusal brings its own suspension separately from anything the court decides.
-
15. You have had to leave the pavement onto a loose gravel shoulder and now need to stop. How should you brake?
Show answer
Answer D: Use both brakes gently and evenly, expecting a much longer stopping distance
Loose gravel cuts available traction sharply, so apply both brakes lightly and smoothly and allow far more room than you would need on pavement.
-
16. You are turning left into a street that is divided by a raised median. Which side should you enter?
Show answer
Answer C: The right-hand roadway, so that you travel on the proper side
A raised median separates two directions of travel, so the turn must be completed into the roadway carrying traffic your way.
-
17. A rider chooses an open face helmet. What does that choice make necessary?
Show answer
Answer A: Separate goggles or a face shield, because the face is uncovered
An open face helmet gives no eye or face protection, so the rider must add goggles or a face shield that will not shatter and that seals against the wind.
-
18. Is it safe to check your phone while stopped at a red light?
Show answer
Answer B: No, you may miss the signal change and hazards around you
Attention does not return instantly when the light changes, and emergency vehicles, pedestrians or a rear-end threat can appear while you are stopped. Stay focused on the road.
-
19. When should a rider use both brakes together?
Show answer
Answer D: Every time the motorcycle slows or stops
Using both brakes for every stop shortens stopping distance and builds the habit the rider will fall back on when a sudden stop is needed.
-
20. A person with a guide dog is standing at the corner facing the street you are about to cross. What should you do?
Show answer
Answer D: Stop well back and wait quietly for them to decide
Blind pedestrians rely on engine sound to judge traffic, so stop back from the crossing and avoid the horn, which only confuses them.
-
21. No plaque stating days or hours accompanies this sign at the intersection. When does the restriction apply?
Show answer
Answer D: At all times, since nothing limits it to particular periods
A regulatory restriction runs continuously unless a supplemental plaque states the days or hours during which it applies.
-
22. Two drivers each have three drinks, one over three hours and one in half an hour. What is the difference?
Show answer
Answer C: The fast drinker reaches a higher peak level
The liver removes alcohol at a steady rate, so drinking faster than the body can clear it pushes the blood alcohol level much higher.
-
23. Visibility drops suddenly and you decide to leave the highway. What is the safest way to do it?
Show answer
Answer A: Take the next exit or a wide pull off, well clear of the traffic lanes
Get right off the traveled way, and off the shoulder too if you can, because vehicles in poor visibility often drift onto the shoulder.
-
24. What is the friction zone of the clutch?
Show answer
Answer A: The range of lever travel where power starts to reach the rear wheel
Easing the clutch lever into the friction zone lets the engine drive the rear wheel gradually, which is what makes a smooth start from a stop possible.
-
25. On a narrow two-lane road a line of vehicles has built up behind you. What is the safe and courteous action?
Show answer
Answer D: Pull into a turnout or a safe wide spot and let them go by
A slow vehicle holding up a queue invites risky passing; using a turnout clears the road without anyone having to take a chance.
