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

Four to six seconds
Eight to ten seconds
One second
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.
