Which behavior most increases the risk of striking the rear of a vehicle that stops suddenly?
Correct answer: C. – Following the vehicle ahead too closely
Following too closely reduces the distance available to react and stop if the vehicle ahead brakes suddenly. Drivers must maintain a reasonable and prudent space based on speed, traffic, and highway conditions. The driver manual recommends allowing a three- to four-second following interval under ordinary conditions.
