- B. 180 days

- B. 10 to 25 feet from the nearest rail
- C. 50 to 100 feet from the nearest rail
- D. 15 to 50 feet from the nearest rail (correct)

3. 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.

4. What is the danger zone around a large truck where the truck driver cannot see you?
- A. Only behind the trailer and on its right
- B. In front, behind, and along both sides (correct)
- C. Only beside the cab on the driver's side
- D. Large trucks have no blind spots with modern mirrors
Why: Large trucks have significant blind spots (no-zones): directly in front (20 feet), directly behind (30 feet), to the right (2 lanes wide), and to the left (1 lane). If you cannot see the driver's face in their mirror, they cannot see you.

5. A 'LANE ENDS' warning sign (showing one lane merging into another) means:
- A. Your lane ends - merge over (correct)
- B. A new lane opens on your right
- C. The highway ends ahead
- D. Two-way traffic ahead
Why: A lane-ends sign warns that the number of lanes is being reduced ahead. Merge safely into the continuing lane before your lane disappears.

6. Hydroplaning is most likely to occur when:
- A. Driving slowly through deep, soft snow on a hill
- B. Driving fast on a wet road, mainly with worn tires (correct)
- C. Driving on dry pavement on a very hot day
- D. Braking gently on an icy road in the cold
Why: Hydroplaning happens when a layer of water builds between your tires and the road, usually at higher speeds on wet pavement. Worn tires and standing water increase the risk. Slow down in the rain to keep tire contact with the road.
