1. Which of these is never a legal place to park?
Show answer
Answer C: In a crosswalk, on a sidewalk or within an intersection
Crosswalks, sidewalks and intersections must stay clear so that pedestrians can cross and drivers can see approaching traffic.
-
2. The road is icy and visibility is poor, but you are driving at the posted speed limit. Is this acceptable?
Show answer
Answer A: No, because you may never drive faster than is safe for the conditions
Under the basic speed rule a driver must travel at a speed that is reasonable for the actual conditions, so a legal posted speed can still be an unlawful and unsafe speed.
-
3. Two lanes at the corner are marked for right turns. What does that require of you?
Show answer
Answer A: Keep your own lane through the turn and into the matching new lane
Dual turn lanes work only if each vehicle stays in its own lane all the way round and finishes in the corresponding lane of the new street.
-
4. What must you be sure of before you pull out to pass on a two-lane road?
Show answer
Answer A: That the road ahead is clear far enough for the whole pass
You need enough clear road to pull out, pass and return before any oncoming vehicle arrives, and you must judge that distance before you start.
-
5. Your light is green but the traffic beyond the intersection is stopped and there is no room on the far side. What should you do?
Show answer
Answer A: Wait behind the line until you can clear the far side
Entering an intersection you cannot clear blocks the cross traffic when their signal turns green, so you wait behind the line.
-
6. At a railroad crossing with no gates and no flashing lights, the crossbuck is normally combined with which sign?
Show answer
Answer C: A yield sign, or a stop sign where an engineering study calls for one
At a passive crossing the crossbuck forms an assembly with a yield sign, or with a stop sign when an engineering study or engineering judgment supports it, so the driver knows who must give way to the train.
-
7. The hood of your vehicle flies open while you are driving and blocks your view. What should you do?
Show answer
Answer A: Look through the gap beneath the hood or out the side window, slow down and pull off the road
You usually still have a narrow view under the raised hood or through the side window. Use it to steer, slow gradually and get clear of traffic before securing the hood.
-
8. Someone appears seriously injured after a crash. What should you generally do?
Show answer
Answer C: Call for emergency help and avoid moving the person unless there is an immediate danger such as fire
Moving an injured person can worsen spinal or internal injuries, so summon trained help and leave the person in place unless staying there is more dangerous than moving.
-
9. Why is following distance measured in seconds rather than in car lengths?
Show answer
Answer A: Because a time gap automatically grows with speed, while a fixed number of car lengths does not
A gap counted in seconds keeps the same margin of reaction time at any speed, whereas a fixed number of car lengths becomes far too small as speed rises.
-
10. What do zero tolerance laws mean for a driver who is under 21?
Show answer
Answer B: They commit a violation at an alcohol level far below the adult limit
Drivers under 21 may not legally drink, so every state sets a limit far below the adult one and treats even a trace reading as a violation. The exact figure is set by each state, and the penalty usually includes losing the license.
-
11. At an intersection where every approach carries this sign, two drivers arrive at exactly the same instant. Which of them goes first?
Show answer
Answer C: The driver on the right
Order of arrival decides who goes first, and when two vehicles arrive together the driver on the right proceeds while the other gives way.
-
12. A dust storm is blowing across the highway ahead of you. What is the recommended response?
Show answer
Answer B: Leave the road if you can, park well clear and take your foot off the brake
Get well off the pavement, switch the lights off and keep your foot off the brake, so drivers still on the road do not follow your tail lights off the highway.
-
13. 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.
-
14. During the reversing part of a three-point turn, where should you be looking?
Show answer
Answer C: Over your shoulder through the rear window, glancing both ways
You look through the rear window in the direction the car is moving, checking both ways for traffic and people, because mirrors and cameras leave blind areas.
-
15. How can you tell a tire has reached its wear limit without measuring it?
Show answer
Answer C: The wear bars across the grooves become level with the tread
Molded bars sit at the bottom of the grooves. Once the surrounding tread has worn down to them, the tire has reached the end of its safe life.
-
16. What visual acuity does Missouri require to pass the driver license vision test?
Show answer
Answer D: At least 20/40 with either eye or with both eyes
Missouri's standard is at least 20/40 acuity with either or both eyes, together with peripheral vision of at least 55 degrees in each eye.
-
17. A Missouri motorist wants to satisfy the financial responsibility law with a surety bond instead of a policy. What amount must be filed?
Show answer
Answer A: $75,000, or $150,000 for a real estate bond
Missouri accepts a surety bond, certificate of deposit or other securities in place of a liability policy, filed at $75,000 or $150,000 if backed by real estate.
-
18. Where is a U-turn generally the most reasonable choice?
Show answer
Answer B: At an intersection where it is permitted and you can see well both ways
A U-turn needs a legal place and a long clear view in both directions, which is why a permitted intersection with open sight lines is the usual choice.
-
19. On loose gravel or deep fresh snow, how does an antilock system affect the stopping distance?
Show answer
Answer D: It can lengthen it, although you keep the ability to steer
On loose surfaces a locked wheel piles up a wedge of gravel or snow that helps it stop, so the antilock stop can be longer even though steering still works.
-
20. You are on a four-lane divided highway and a vehicle in your lane is stopped waiting to turn left across the median. What is the normal way past?
Show answer
Answer D: Slow down and go by in the lane to the right when it is clear
On a multilane road the free lane beside you is the lawful place to go past a vehicle waiting to turn, and the median is not part of the roadway.
-
21. You want to move into the right lane just as an entrance ramp joins the highway at that point. What is the better choice?
Show answer
Answer B: Wait until you are past the merge area so you do not squeeze the entering traffic
The merge area is where ramp traffic has to find a gap, so adding a lane change of your own into the same space creates a conflict.
-
22. How should you follow a school bus in traffic?
Show answer
Answer A: Far enough back to see its lights and stop in time
A school bus stops often and with little warning, so a longer following distance gives you time to see the lights come on and stop clear of it.
-
23. Traffic in your lane is backed up and the paved shoulder looks clear. May you drive along it to get past?
Show answer
Answer C: No, the shoulder is not a travel lane
Passing must be done within the roadway; driving on the shoulder to get around traffic is prohibited and surprises anyone entering from the right.
-
24. On a multi-lane street, a yield line is painted well back from an unsignalized crosswalk rather than right at it. Why?
Show answer
Answer D: So drivers in the other lanes can see the pedestrian
Setting the yield line back keeps a stopped vehicle from hiding a crossing pedestrian from drivers in the next lane, which is a common cause of these crashes.
-
25. An entrance ramp joins a highway just before an exit ramp leaves it. What should you expect in that short section?
Show answer
Answer D: Vehicles crossing paths as some enter and others leave
In a weaving section entering traffic moves left while exiting traffic moves right over the same short stretch, so lane changes there need extra room and extra care.
