When traveling at 55 mph on a highway, what is the minimum recommended following distance in feet?

The minimum recommended following distance when traveling at 55 mph on a highway is 400 feet. This distance is important for allowing adequate time to react to any sudden stops or emergencies by the vehicle in front of you. Maintaining a safe following distance helps ensure that you have sufficient space to brake safely without risking a collision.

In general, the rule of thumb for determining a safe following distance is to allow one car length for every 10 mph you are traveling, plus additional space based on the road conditions, visibility, and traffic. At 55 mph, this calculation suggests that a distance of around 400 feet is appropriate to ensure safety and reduce the risk of accidents. Keeping a larger distance can also help mitigate the effects of tailgating and allow for better visibility of the road ahead.
