Question 19 of 50
Score: 0/0When driving a 30-foot long vehicle at 55 mph, how much following distance should you leave between you and the vehicle ahead?
ExplanationA general rule is to allow at least one second of following distance for every 10 feet of vehicle length. At 30 feet, that means 3 seconds minimum — but at higher speeds like 55 mph, increasing it to 4 seconds is safer.
