1. 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.
-
2. A diamond-shaped sign is used to
Show answer
Answer A: warn of a condition on or next to the road that may call for caution
The diamond is the standard shape of the warning series, which alerts drivers to conditions that would otherwise not be obvious in time to react.
-
3. 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.
-
4. Where should a rear-facing infant seat never be placed?
Show answer
Answer C: In a front seat with an active passenger air bag
A deploying front air bag strikes the back of a rear-facing seat with enormous force. Rear-facing seats belong in the back seat.
-
5. A speed limit sign carries a second panel reading TRUCKS 55. What does that panel do?
Show answer
Answer B: It sets a lower legal limit for trucks
A truck speed limit panel is regulatory, so trucks are bound by the lower figure while other traffic keeps to the main limit.
-
6. Why can a motorcycle ahead of you slow down without any warning light showing?
Show answer
Answer B: The rider may slow by downshifting or rolling off
Riders often lose speed by closing the throttle or changing down, which does not switch on the brake light, so watch the machine itself and keep back.
-
7. A train has just cleared a crossing that carries two sets of tracks. What should you do?
Show answer
Answer B: Wait and look both ways for a second train
A passing train hides a second train on the other track, so wait until the signals stop and you can see that both tracks are clear.
-
8. You are approaching a refuse collection truck working along your street. What should you expect?
Show answer
Answer D: Workers stepping into the road around the truck
Collection crews move constantly between the truck and the curb, often from where you cannot see them, so slow right down and pass only when the whole area is clear.
-
9. 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.
-
10. 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.
-
11. A signal on an entrance ramp changes from red to green and lets one vehicle at a time onto the highway. What should you do?
Show answer
Answer A: Stop on the red and go on the green, one vehicle for each green
A ramp meter spaces vehicles out so they join the highway one at a time instead of arriving as a group, and it is a traffic signal like any other.
-
12. Your vehicle has daytime running lights. Why should you still switch on the headlights at dusk?
Show answer
Answer B: Daytime running lights usually do not light the tail lights, so you are hard to see from behind
On many vehicles the daytime running lights illuminate only the front. Without the headlight switch on, the rear of the vehicle stays dark and the dash may still look lit.
-
13. Why are sign shapes and colors standardized across the whole country?
Show answer
Answer D: So a driver knows the kind of message before reading it
Uniform shapes and colors let a driver classify a sign as regulatory, warning or guide from a distance, before the legend can be read.
-
14. Why should heavy objects in the passenger compartment be secured?
Show answer
Answer A: Because loose objects fly forward in a crash and can injure the people
Anything loose keeps traveling at the speed of the vehicle when the vehicle stops, so it strikes the occupants with great force.
-
15. A curb lane is marked BUS ONLY 7 AM TO 9 AM. What may the driver of a car do?
Show answer
Answer A: Use the lane outside those hours
A part-time bus lane is reserved only during the posted period, and outside it the lane serves general traffic like any other.
-
16. A pedestrian is waiting to cross ahead of you and you have slowed down. What helps most?
Show answer
Answer D: Making eye contact, so that you both know you have seen each other
Eye contact confirms that you have seen each other; waving someone across can send them into the path of another vehicle.
-
17. Another driver is behaving aggressively toward you. What should you do?
Show answer
Answer D: Avoid eye contact, give them room to go on their way and do not respond to provocation
Responding to an aggressive driver escalates the conflict, while creating distance and refusing to engage takes you out of the situation. Report serious threats once you can do so safely.
-
18. How does eating a large meal before drinking affect impairment?
Show answer
Answer D: It slows absorption but the alcohol still reaches the blood and impairs you
Food delays how quickly alcohol enters the bloodstream, which can make the peak arrive later, but all of the alcohol is eventually absorbed.
-
19. You are first in the queue at a red light with a marked crosswalk. Where should your vehicle stop?
Show answer
Answer A: Behind the stop line, so that the crosswalk stays clear
Stopping short of the line keeps the crosswalk usable for people on foot and keeps your vehicle out of the path of turning traffic.
-
20. Which family of signs normally uses a rectangle that is wider than it is tall?
Show answer
Answer B: Guide signs, which name routes and destinations
Guide signs are laid out as horizontal rectangles because they have to carry route numbers, place names and distances side by side.
