JJ Keller Entry Level Driver Training for CDL (Commercial Driver’s License) Practice Test

The 11-hour limit in driving hours refers to the maximum amount of time a commercial driver is permitted to drive within a single work shift. This regulation is in place to ensure driver safety and to minimize fatigue, which can lead to accidents.

After a driver has accumulated 11 hours of driving time, federal regulations require that they take a mandatory rest period of 10 consecutive hours off duty. This helps to ensure that drivers have adequate rest to perform safely when they resume driving. The requirement is part of the Hours of Service regulations set forth by the Federal Motor Carrier Safety Administration (FMCSA).

While the other options touch on aspects of driving time and breaks, they do not accurately reflect the specific regulation regarding the 11-hour limit. Option A suggests taking breaks before reaching the 11-hour limit, which isn't aligned with the strict requirements of the law, as breaks are not defined by the 11-hour threshold in that context. Option C inaccurately implies that frequent breaks can extend driving hours beyond the limit, which contradicts the established regulation. Option D, while mentioning the maximum driving time, does not specify the necessary rest period that follows driving for 11 hours. Therefore, the requirement after reaching 11 hours makes option B the correct answer.
