What is the 30-minute break rule?
It says you cannot keep driving once more than 8 hours of driving time have passed without a break of at least 30 consecutive minutes (49 CFR 395.3(a)(3)(ii)). The 8 hours count driving time since the last qualifying break, not clock time. After a qualifying break, a new count of 8 hours of driving starts.
What counts as the 30-minute break?
Any consecutive 30 minutes with no driving. It can be off-duty time, sleeper berth time, on-duty not driving time, or a combination. So fueling or a paperwork stop can count if you are not driving.
Does the 30-minute break stop the 14-hour clock?
No. The 14-hour period runs through breaks (49 CFR 395.3(a)(2)). Taking a break is required, but it does not give back any time in the window.
Who does not have to take the 30-minute break?
Drivers who qualify for the short-haul exceptions in 395.1(e)(1) or (2) are exempt. So are drivers who carry commercial bees or livestock, while those are on the vehicle (395.1(u) and (v)). Some waiting can count as the break. A concrete mixer driver who waits 30 minutes or more at a job site with no other work can count it (395.1(t)). Attendance time on an explosives load can count too (395.1(q)). Drivers outside Part 395, such as under the agricultural exemption, have no break rule.
