When two lanes merge and there are 'zipper merge' signs, you should:

Use both lanes to the merge point, then take turns

Stop and wait for all traffic to clear

Let all vehicles in the other lane go first

Merge early - as soon as you see the sign - to be polite

When driving at night, you should:

Slow down and leave more following distance

Use parking lights so you do not dazzle others

Keep your daytime speed and following distance

Look straight at oncoming headlights to judge them

When you reach an intersection with a flashing red light in your direction and a flashing yellow in the cross direction, you must:

Stop, then go when safe - cross traffic won't stop

Stop and wait until your light turns solid green

Stop, then go first - cross traffic must yield

Slow down and go - the cross traffic has to stop

Sample questions from this test, with answers

Want to test yourself first? Take the test above before reading these. Every answer below is checked against the source shown.

1. Nevada's Basic Speed Rule means you must:
- A. Drive at a speed reasonable for conditions (correct)
- B. Always drive at exactly the posted limit
- C. Match the speed of the traffic around you
- D. Never drive faster than 55 mph anywhere
Why: Under Nevada's Basic Rule, the proper speed may be well below the posted limit depending on traffic, weather, and road conditions.

2. A red and white 'WRONG WAY' sign tells you:
- A. A one-way road begins ahead
- B. You are going against traffic (correct)
- C. You must yield to oncoming cars
- D. A detour is ahead - follow it
Why: A 'Wrong Way' sign means you are heading the wrong direction on a one-way road or ramp. Stop, check for traffic, and safely turn around immediately.

3. Worn or bald tires are dangerous primarily because they:
- A. Wear out the brakes faster than normal
- B. Reduce traction and raise the risk of skidding (correct)
- C. Only matter on snow and ice, not on wet pavement
- D. Cause the car to pull hard to one side
Why: Bald or worn tires have little tread to grip the road or channel away water. This dramatically increases stopping distance and the risk of hydroplaning and skidding, especially in wet conditions.

4. When should you use your vehicle's emergency hazard lights?
- A. When parking briefly in a no-parking zone
- B. When your car is disabled on or near the road (correct)
- C. To thank a driver who let you merge
- D. When you plan to change lanes or make a turn
Why: Hazard lights warn others that your vehicle is stopped, disabled or a hazard. Rules for using them while moving (for example in heavy rain) differ between states, so follow your state handbook.

5. In most states, which left turn may you make on a steady red light after a full stop, if no sign forbids it?
- A. From a two-way street onto another two-way street
- B. From any street when no oncoming car is in sight
- C. From a two-way street into a store's driveway
- D. From a one-way street onto another one-way street (correct)
Why: Most states allow a left turn on red from a one-way street onto another one-way street that carries traffic to the left. You must stop fully and yield to pedestrians and traffic first.

6. A warning sign showing a truck on a downgrade indicates:
- A. A truck weigh station ahead
- B. A steep downhill grade ahead (correct)
- C. A runaway truck ramp ahead
- D. A truck crossing ahead
Why: A sign showing a truck on a slope warns of a steep downhill grade. Trucks should use a lower gear; all drivers should check brakes and control speed.
