1. You are approaching a tow truck stopped on the shoulder with its lights on. What does Nevada require?
Correct answer: Slow below the posted limit, proceed carefully, be ready to stop, and move out of the adjacent lane if you safely can
The duty covers law enforcement, tow trucks, highway department vehicles, garbage trucks and anyone attending to a vehicle repair at the roadside.

2. What does Nevada's Basic Rule require of a driver?
Correct answer: Choose a reasonable and proper speed for traffic, weather, visibility and road conditions
Posted numbers assume good conditions. When rain, ice, heavy traffic or a narrow winding road change things, the lawful speed can be well below the sign.

3. If you double your speed from 30 mph to 60 mph, what happens to braking distance?
Correct answer: It becomes roughly four times as long
Braking distance climbs far faster than speed does. Twice the speed needs about four times the pavement to shed it.
4. The handbook lists 25 mph as the typical limit in which areas?
Correct answer: Business and residential districts
Twenty-five is the figure given for business and residential streets and for school zones, while reduced-speed approaches into towns are shown as forty-five.

5. What speed limits does the handbook list for Nevada school zones?
Correct answer: 15 or 25 mph
School zones post either fifteen or twenty-five miles per hour, and signs or flashing yellow lights show when the reduced limit applies.
6. How does a wet highway change your stopping distance?
Correct answer: It can more than double it
Wet pavement can push the distance past twice what dry road requires, and the first rain of the season is worse still because oil lifts to the surface.
7. Which crash type does the handbook identify as the most common on Nevada roads?
Correct answer: Rear-end collisions
Striking the vehicle in front is the number one crash in the state, which makes judging following distance one of the most valuable driving skills.
8. When is a Nevada school-zone speed limit in force unless signs say otherwise?
Correct answer: From a half hour before classes begin until a half hour after they end on school days
The window opens thirty minutes ahead of the first bell and closes thirty minutes after the last one on days school is in session.
9. In heavy rainfall, at what speeds do most cars begin to hydroplane?
Correct answer: Between 35 and 55 mph
Somewhere between thirty-five and fifty-five miles per hour the tires start riding on water instead of pavement, and steering and braking control disappear.
10. At 40 mph or below, what is the minimum following interval the handbook sets?
Correct answer: Two seconds
Two seconds is the floor, not the target. Many instructors push that up to four, and slick roads or higher speeds demand more still.

11. Roughly how long does the handbook say it takes to stop from 55 mph with good brakes on a good road?
Correct answer: Nearly seven seconds
Even under ideal conditions the stop takes close to seven seconds, which is why following intervals have to grow as speed climbs.

12. On a Nevada road with two or more lanes going your way, what must slower drivers do?
Correct answer: Move right so faster traffic can get by
Holding up a queue is its own hazard, because impatient drivers behind you start attempting passes where it is not safe to make one.
