How the exam asks it

Near Bodegraven you are driving without a trailer and without a heavy load, but it is snowing lightly. What following distance do you keep?

  1. 3 seconds, because snow on its own is reason enough
  2. 2 seconds, because 3 is only for a trailer or a heavy load
  3. 4 seconds, because in snow you double the normal distance
Show the answer

Correct answer: 3 seconds, because snow on its own is reason enough

False — you think only load counts. Rain, snow and fog are each on their own a reason for 3 seconds, even without a trailer or heavy load.

Why learners get this wrong: The 3-second rule only applies with a heavily loaded vehicle or a trailer/caravan, not with rain, snow or fog.
