When driving in fog, you should
- slow down.
- increase your following distance.
- use your low-beam headlight.
- do all of the above. ✓
Answer: D. do all of the above.
When riding in fog, do all of the listed actions: slow down, increase your following distance and use your low-beam headlight.
Why this is the answer
The motorcycle handbook's fog tips tell riders to slow down gradually to a speed that suits the conditions and to use low-beam lights, because high beams reflect off moisture in the fog and make visibility worse. It also says to increase your following distance so you have extra room to brake safely. Since the question asks what you should do in fog and each listed action appears in those tips, the complete answer is to do all of them. The handbook also says avoiding fog altogether is best, but if you are caught in it, these steps apply.
Why the other answers are wrong
- A. slow down. — Slowing down is part of the handbook's fog advice, but it is only one step and leaves out the extra following distance and low-beam lights.
- B. increase your following distance. — Increasing your following distance is also advised, but on its own it misses the need to slow down and use low-beam lights.
- C. use your low-beam headlight. — Using low-beam lights is correct for fog, but choosing only that ignores the handbook's instructions to slow down and leave more braking room.
Remember it
High beam bouncing back in fog is your cue to switch low, ease off and leave room.
