During poor visibility conditions, what minimum following distance should you maintain?

  1. Four to six seconds

  2. Eight to ten seconds

  3. One second

  4. Five car lengths

The correct answer is: Eight to ten seconds

During poor visibility conditions, such as heavy rain or fog, you should maintain a minimum following distance of eight to ten seconds. This extended following distance allows for a larger safety buffer in case of sudden braking or other unexpected situations. Option A is incorrect because four to six seconds is the recommended following distance in ideal weather conditions. Option C of one second is far too short and does not allow for enough reaction time. Option D of five car lengths is not a reliable measure as it varies depending on the size of the cars.
