17. If you are driving near a large commercial vehicle, you should:

Follow the large vehicle closely to reduce wind drag on your vehicle.

Avoid driving beside it for long stretches of time.

Drive on its right side when on curves and hills.

Because large commercial vehicles have large blind spots on each side, you should avoid driving beside them for long periods of time.

18. In traffic moving at 50 to 55 mph, you are least likely to have an accident if you:

Drive a few miles per hour faster than most other vehicles.

Stay within that speed range.

Drive a few miles per hour slower than most other vehicles.

You should adjust your speed to travel smoothly with the other traffic on a roadway (provided that the other traffic is driving within the posted speed limits). Remember that vehicles moving in the same direction at the same speed cannot hit each other. Crashes involving multiple vehicles often happen when some vehicles are traveling at different speeds than others.

19. Your license can be suspended if you are under 21 and drive with a blood alcohol level of:

0.15 percent or more.

0.08 percent or more.

Any amount.

There is zero tolerance for alcohol use by drivers under age 21. If you are under 21, the detection of any trace of alcohol in your system will result in stiff penalties, including the suspension of your license for two years.

20. You are involved in a minor collision at an intersection. There are no injuries and there is very little vehicle damage. You should:

Leave your vehicle in the traffic lane until law enforcement arrives.

Move your vehicle out of the traffic lane, if possible.

Not move your vehicle for any reason.

After a collision, if no one has been injured or killed and you can safely do so, you should move your vehicle out of the traffic lane.

First come to a complete stop.

Wait until the light changes.

22. It is more dangerous to drive at night than during the day because:

You cannot see as far ahead at night.

The road is always more slippery at night.

Your reaction time is slower at night.

With decreased visibility and the glare of oncoming headlights, you cannot see as far ahead at night as you can during the day. Always use headlights and exercise caution when driving in the dark.

23. Alcohol in any concentration is:

A stimulant.

A depressant.

Neither of the above.

Alcohol, in any concentration, is a depressant. It slows all nerve impulses and bodily functions, resulting in a lessening of inhibitions and negatively affecting a consumer's ability to concentrate and stay alert.

24. Should you always drive more slowly than other traffic?

No, you can block traffic when you drive too slowly.

Yes, it is a good defensive driving technique.

You must drive more slowly than usual when there is heavy traffic or bad weather. However, if you block the normal and reasonable movement of traffic by driving too slowly, you may be cited.

Slippery when wet.

Stop sign ahead.

No U-turn.

All roads are slippery and dangerous when wet. This sign warns of conditions that can cause a driver to lose control of a car. A driver should slow down when coming upon wet pavement because it takes longer to stop.
