Arkansas Driving Permit Practice Test

At 55 mph, how long does it take for a tractor-trailer to come to a complete stop?

500+ feet 450+ feet 400+ feet 350+ feet

Correct Answer:

400+ feet

Explanation:

A tractor-trailer traveling at 55 mph takes approximately 400 feet to come to a complete stop. This is because at high speeds, it takes much longer for the vehicle to slow down and stop, especially due to their larger size and weight. Option A, 500+ feet, is too high of a distance as modern trucks have improved braking systems and can stop in a shorter distance. Option B, 450+ feet, is also too high. Option D, 350+ feet, is too low and would be the stopping distance for a smaller vehicle traveling at the same speed.
