A driver comes to a roadway covered with flood water and cannot tell how deep it is. What is the safest choice?
- Drive through quickly before it gets deeper
- Follow another vehicle through at the same speed
- Stop in the water and wait for it to recede
- Turn around and find an alternate route
Correct answer: Turn around and find an alternate route. It is often impossible to judge the true depth of a flooded roadway by looking at it, and the water may be hiding a washed-out road or a stalled vehicle. The safest choice is to turn around and take another route rather than guessing.

A driver on an open road with light traffic and good visibility is traveling 25 mph under the posted limit for no clear reason, and several cars are backed up behind. What mistake is this driver making?
- None — driving slowly is always the safest choice.
- It is only a problem on interstate highways.
- Blocking traffic flow without a valid reason.
- Nothing, since they are still under the limit.
Correct answer: Blocking traffic flow without a valid reason.. Driving far below the normal, reasonable speed of traffic without a valid reason can block the flow of traffic and lead to a citation, even though the driver is under the limit.

Why are regulatory signs generally white or red with black or white lettering, instead of yellow like warning signs?
- Because red and white paint is simply cheaper to produce
- Because those specific colors are required by law for headlights
- There is no real reason; it is only a modern styling trend
- So drivers can tell a binding rule apart from a warning
Correct answer: So drivers can tell a binding rule apart from a warning. The color scheme helps drivers instantly separate a rule they must obey from a warning that only alerts them to a hazard.

- 0.20%

While the warning lights are flashing in a marked school zone in New Jersey, what speed limit applies?
- 10 mph
- 35 mph
- 25 mph
- 15 mph
Correct answer: 25 mph. In New Jersey, when the school zone's warning lights are flashing, the speed limit drops to 25 mph to protect children near the school.
If you are driving through a school zone in New Jersey and the warning lights are actively flashing, the speed limit changes to:
- 30 mph
- 25 mph
- 45 mph
- 40 mph
Correct answer: 25 mph. A flashing warning light means the school zone limit is in effect; in New Jersey this limit is 25 mph.
A parent is installing a rear-facing infant car seat. Where should this seat never be placed?
- In the front seat of a vehicle with an active airbag
- In the middle of the back seat
- On the passenger side of the back seat
- Anywhere without a top tether strap
Correct answer: In the front seat of a vehicle with an active airbag. A rear-facing car seat should never be placed in the front seat of a vehicle equipped with an airbag. If the airbag deploys in a crash, it can strike the back of a rear-facing seat with enough force to seriously injure the child.

A driver later realizes they cannot remember the last few miles they just drove. What is a likely explanation?
- The road must not have had anything interesting to look at
- This is completely normal and has nothing to do with fatigue
- The vehicle's cruise control was steering on its own
- A brief microsleep, a few seconds of unintentionally nodding off
Correct answer: A brief microsleep, a few seconds of unintentionally nodding off. Extreme drowsiness can cause a microsleep, a brief lapse of a few seconds where a driver unintentionally nods off without fully realizing it, which can explain not remembering the last stretch of road.

A driver takes two different medications at the same time, in addition to having a drink. Why is this combination especially dangerous?
- Each drug cancels out the effects of the others
- Only the strongest of the drugs will have any effect
- The effects can add up, and alcohol can hide the warning signs
- Combining substances has no more effect than taking one alone
Correct answer: The effects can add up, and alcohol can hide the warning signs. Taking more than one drug at the same time, especially combined with alcohol, can create a cumulative effect that is more dangerous than any single substance alone, and alcohol can mask the warning signs that a drug is impairing the driver.
