A driver navigates a 70-foot articulated transport vehicle along a dry highway at a cruising speed of 50 mph. Under standard commercial driving safety rules, what is the minimum required following distance, in seconds, that must be maintained behind the lead vehicle?
Answer: 8 seconds
Answer
8 seconds of following distance
According to standard commercial driver guidelines, following distance is calculated as 1 second per 10 feet of vehicle length at lower speeds, plus 1 additional second when traveling at 40 mph or faster. For a 70-foot vehicle traveling at 50 mph, the base requirement is seconds. Adding the 1-second adjustment for driving at 50 mph yields a total of 8 seconds.
