DOT Hours of Service Regulations 3

Question 1

A passenger-carrying CMV driver has been on duty for 13 hours and has driven 9 hours. Which HOS limit has been violated?

Accepted Answer

The 10-hour driving limit

Answer

Passenger-carrying drivers are limited to 10 hours of driving, and this driver has exceeded that with 9 hours — wait, 9 < 10, but the question states 9 hours driven which is under 10; however re-examining: passenger carriers have a 10-hr drive limit so 9 hrs driving is fine, but on-duty at 13 hrs is fine under the 15-hr rule. Actually the driving limit is 10 hrs; 9 hrs driving is not a violation. Let me restate: only the 10-hour driving limit applies here if driving were 10+. At 9 driving and 13 on-duty, no violation exists yet.

Question 2

Which record of duty status entry is required when a CMV driver is required to wait at a shipper or receiver facility for more than 1 hour?

Accepted Answer

On-duty not driving

Answer

Time spent waiting at a shipper or receiver beyond 1 hour must be recorded as on-duty not driving.

Accepted Answer

Question 4

An ELD malfunctions mid-trip. What must the driver do according to 49 CFR 395.34?

Accepted Answer

Switch to paper logs and carry them for the remainder of the trip, not to exceed 8 days

Answer

Upon ELD malfunction, the driver must reconstruct the current day's log on paper and continue with paper logs for up to 8 days while the carrier arranges repair or replacement.

Question 5

A driver uses the 34-hour restart provision. At minimum, how many periods from 1:00 a.m. to 5:00 a.m. must the restart include?

Accepted Answer

None — the 1–5 a.m. requirement was removed

Answer

The requirement for two 1:00–5:00 a.m. periods was suspended by Congress and is no longer in effect; the restart simply requires 34 consecutive hours off duty.
