1. What is the minimum distance recommended by the National Highway Traffic Safety Administration between the center of the breastbone and the steering wheel?
Answer: Ten inches. The handbook specifies a minimum distance of ten inches for proper seating posture.
Missouri driver handbook, page 57: “The National Highway Traffic Safety Administration recommends drivers sit with at least ten inches between the center of their breastbone and the center of the steering wheel.”
2. When driving behind a truck or bus, how can you determine if the driver is able to see you?
Answer: If you can see the driver in his or her rearview mirrors. The handbook states that visibility of the driver in the rearview mirrors indicates whether the driver can see you.
Missouri driver handbook, page 31: “If you are driving behind a truck or a bus and cannot see the driver in his or her rearview mirrors, the driver of that vehicle cannot see you.”
3. What action should a driver take when being tailgated by another vehicle if there is no right lane available?
Answer: Wait until the road ahead is clear and then reduce speed slowly. The handbook advises waiting for a clear road and reducing speed slowly if no right lane exists, rather than slowing quickly or stopping abruptly.
Missouri driver handbook, page 59: “If there is no right lane, wait until the road ahead is clear and then reduce speed slowly.”
4. What is the correct procedure for leaving a parked vehicle with a manual transmission?
Answer: Leave the vehicle in gear and set the parking brake. The handbook specifies that manual transmission vehicles must be left in gear, unlike automatics which are left in park.
Missouri driver handbook, page 37: “Always set your parking brake when you park. Leave the vehicle in gear if it has a manual transmission, or in park if it has an automatic transmission.”
5. When making a right turn, why should a driver avoid swinging wide to the left before turning?
Answer: So the driver behind may think you are changing lanes or turning left and try to pass you on the right. The handbook states that swinging wide can confuse following drivers into thinking you are changing lanes or turning left, leading them to pass on the right.
Missouri driver handbook, page 27: “If you swing wide, the driver behind you may think you are changing lanes or going to turn left, and may try to pass you on the right.”
6. Where should the shoulder belt be positioned when wearing a seat belt?
Answer: Across the chest. The handbook instructs drivers to place the shoulder belt across the chest for proper restraint.
Missouri driver handbook, page 57: “Seat belts should always be worn with the lap belt low and snug across the hips and the shoulder belt across the chest.”
7. When is a driver NOT required to stop for a school bus that is loading or unloading children?
Answer: When traveling the opposite direction on a highway divided by a median. Drivers on the opposite side of a divided highway are exempt from stopping for school buses, unlike those on undivided roads.
Missouri driver handbook, page 26: “When you are traveling the opposite direction of a school bus on a highway divided by a median where the vehicles traveling one direction are on a totally separate road from the vehicles traveling the opposite direction”
8. When stopped by law enforcement at night, what action should you take to assist the officer with visibility?
Answer: Turn on your interior lights as soon as you stop. The handbook instructs drivers to turn on interior lights immediately upon stopping at night to help the officer see inside, distinguishing this from other lighting behaviors.
Missouri driver handbook, page 63: “To assist with visibility, turn on your interior lights as soon as you stop to help the officer see inside your vehicle.”
9. According to the handbook, how should you position your wheels when parking on a hill?
Answer: Turn your wheels sharply towards the side of the road. The handbook instructs drivers to turn wheels toward the curb so the vehicle rolls away from traffic if it starts moving.
Missouri driver handbook, page 37: “When you park on a hill, turn your wheels sharply towards the side of the road.”
10. How should a driver treat a traffic signal that is dark or not working?
Answer: Operate as if it were a four-way stop. The handbook states that non-functioning signals are to be treated exactly like a four-way stop intersection.
Missouri driver handbook, page 47: “Dark signals, or traffic signals that aren’t working operate as a four-way stop.”
11. What is the default speed limit in any city, town, or village in Missouri unless posted otherwise?
Answer: 25 mph. The handbook establishes 25 mph as the standard speed limit for municipal areas in the absence of posted signs.
Missouri driver handbook, page 52: “The speed limit in any city, town, or village is 25 mph, unless posted otherwise.”
12. According to the handbook, what should a driver do when handling a skid?
Answer: Take your foot off the accelerator and gently turn the steering wheel in the direction the rear wheels are sliding. The handbook instructs drivers to ease off the accelerator and steer gently into the skid without braking hard.
Missouri driver handbook, page 66: “Take your foot off the accelerator, but DO NOT hit the brakes. • Gently turn your steering wheel in the direction that your rear wheels are sliding.”
13. When driving on a highway with a total of four or more lanes, under which circumstance are you permitted to keep to the left lane?
Answer: When you are passing slower traffic. The handbook states that on multi-lane highways, drivers should stay right unless passing slower traffic, allowing entry, or preparing for a left turn.
Missouri driver handbook, page 39: “On highways with a total of four or more lanes (two or more lanes in each direction), always keep to the right unless you are passing slower traffic, letting another driver have room to enter safely, or getting ready to make a legal left turn.”
14. In a Mobile Work Zone, what should a driver expect to see in the lane to designate the correct lane to merge to?
Answer: A protective vehicle with a flashing arrow panel. The handbook specifies that mobile work zones use a protective vehicle with a flashing arrow panel to guide merging, unlike flagging operations which use a person.
Missouri driver handbook, page 55: “When approaching the mobile work zone, a driver should expect to see a protective vehicle in the lane with a flashing arrow panel designating the correct lane to merge to.”
15. What action should a driver take when encountering a 'Wrong Way' sign?
Answer: Pull off the road, turn around, and go back. The instructions for the Wrong Way sign direct the driver to pull off the road, turn around, and return to the correct direction.
Missouri driver handbook, page 51: “As quickly and safely as possible, pull off the road, turn around and go back.”
16. Under what condition is it illegal to possess or purchase alcohol according to the handbook?
Answer: If you are under the age of 21. The handbook directly states that possessing or purchasing alcohol is illegal for individuals under the age of 21.
Missouri driver handbook, page 73: “It is illegal to possess or purchase alcohol if you are under the age of 21.”
17. Why might a tractor-trailer appear to be traveling more slowly than it actually is?
Answer: Because of its large size. The handbook attributes the perception of slower speed directly to the large size of the vehicle.
Missouri driver handbook, page 32: “Because of its large size, a tractor-trailer often appears to be traveling more slowly than its actual speed.”
18. According to the handbook, what is the primary reason for avoiding sudden panic stops?
Answer: It could cause you to lose control of your vehicle and makes it harder for drivers behind you to stop. The handbook states that quick braking risks losing vehicle control and hindering the ability of following drivers to stop safely.
Missouri driver handbook, page 41: “Braking quickly could cause you to lose control of your vehicle. You also make it harder for drivers behind you to stop without hitting you.”
19. Which of the following locations is listed as a place where you should NOT park?
Answer: On a crosswalk or sidewalk. The handbook lists crosswalks and sidewalks as specific no-parking zones, while other options are generally permitted contexts.
Missouri driver handbook, page 37: “Do not park: • In an intersection. • On a crosswalk or sidewalk.”
20. What is the maximum distance a vehicle may travel in a two-way left-turn lane?
Answer: 500 feet. The handbook limits travel in a two-way left-turn lane to no more than 500 feet.
Missouri driver handbook, page 28: “Do not use this lane as travel lane (a vehicle may not travel in this lane for more than 500 feet)”
