To drive safely at night, you should:

  1. Increase your following distance.
  2. Not drive if you are tired.
  3. Make sure your headlights are working properly.
  4. All of the above. ✓

Answer: D. All of the above.

The correct choice is All of the above: increase your following distance, do not drive when tired, and make sure your headlights work properly.

Why this is the answer

The Texas handbook ties safe night driving to several habits, not just one. It says to adjust speed and following distance to road and vision conditions, and when visibility is limited you should be able to stop within the distance you can see ahead. At night, it says to slow down and stay within the area your headlights light up. It also says not to drive if you are tired or unwell. Separately, it says your vehicle should be in good working order, which supports checking that the headlights you must use are working.

Why the other answers are wrong

Remember it

At night, give yourself room, skip the drive if you are tired, and check your lights before you go.
