Which of the following is one of the most common causes of collisions? a. driving on the wrong side of the road b. driving too slowly uphill c. tailgating d. eating while driving

C. Tailgating.

A key part of maintaining your driving space is the four-second following distance rule. This is the minimum legal following distance in Florida. However, many Floridians and communities abroad do not adhere to this law. Because of this, nearly 1/3 of all collisions are due to tailgating -- or the lack of staying (at least) 4 second behind a vehicle in front of you.

Therefore, the answer is Choice C.
