How does the 34-hour restart work under 49 CFR 395.3?

Short answer

A driver can restart the 60/70-hour on-duty limit by taking 34 or more consecutive hours off duty. The 34-hour restart rule allows drivers to reset their weekly on-duty limits after taking at least 34 consecutive hours off duty.

The rule says

"Any period of 7 consecutive days may end with the beginning of an off-duty period of 34 or more consecutive hours." (49 CFR 395.3(c)(1))

"Any period of 8 consecutive days may end with the beginning of an off-duty period of 34 or more consecutive hours." (49 CFR 395.3(c)(2))

In plain English

The 34-hour restart is a way for drivers to reset their weekly on-duty limits. By taking at least 34 consecutive hours off duty, drivers can start a new 7- or 8-day period, depending on their carrier's operations. This allows drivers to get a break and restart their workweek.

What to do

• Ensure drivers take at least 34 consecutive hours off duty to restart the 60/70-hour on-duty limit.
• Update driver schedules and records to reflect the restart.
• Verify that drivers understand the restart rule and its requirements.
• Review and comply with all applicable hours-of-service regulations, including the 11-hour driving limit and 14-hour on-duty limit.
