SUMMARY: FMCSA revises the hours of service (HOS) regulations to limit the use of the 34-hour restart provision to once every 168 hours and to require that anyone using the 34-hour restart provision have as part of the restart two periods that include 1 a.m. to 5 a.m. It also includes a provision that allows truckers to drive if they have had a break of at least 30 minutes, at a time of their choosing, sometime within the previous 8 hours. This rule does not include a change to the daily driving limit because the Agency is unable to definitively demonstrate that a 10-hour limit—which it favored in the notice of proposed rulemaking (NPRM)—would have higher net benefits than an 11-hour limit. The current 11-hour limit is therefore unchanged at this time. The 60- and 70-hour limits are also unchanged.
The purpose of the rule is to limit the ability of drivers to work the maximum number of hours currently allowed, or close to the maximum, on a continuing basis to reduce the possibility of driver fatigue. Long daily and weekly hours are associated with an increased risk of crashes and with the chronic health conditions associated with lack of sleep. These changes will affect only the small minority of drivers who regularly work the longer hours. Read Frequently Asked Questions about this complex and confusing set of rules.
