Issue Background

Hours-Of-Service (HOS)

Full use of 34-hour restart reinstated

In 2013, the federal government mandated restrictions on the 34-hour restart by including consecutive 1:00 a.m. to 5:00 a.m. breaks and limiting use of the restart to once per week.

  • OOIDA worked to temporarily suspend the 2013 provisions until a Congressionally mandated DOT study proved the restrictive provisions improved safety.
  • In March 2017, the study found that restrictions made to the 34-hour restart provided "no net safety benefit." Given the FMCSA's findings, the current rules, which allow unlimited use of the restart, will remain in place.

OOIDA supports providing drivers the flexibility in hours-of-service (HOS) regulations necessary to reduce fatigue, provide for efficient operations, and ensure compliance by all stakeholders. The current regulations are overly complex, provide virtually no flexibility, and in no way reflect the physical capabilities or limitations of individual drivers. They effectively force drivers to be on the road during busy travel times such as morning and afternoon rush hours; when they are tired, fatigued or are simply not feeling well and during severe weather and road conditions. Our top concerns regarding HOS regulations are:

14-hour clock provision

  • The 14-hour rule prohibits driving after the 14th consecutive hour after first coming on duty following 10 consecutive hours off duty. Of those 14 hours, up to 11 can be spent driving.
  • OOIDA believes a more flexible option would better promote safety by letting the driver decide when to rest and when to drive.

Split sleeper berth restriction

  • The required rest period in the sleeper berth must be at least 8 consecutive hours (but less than 10 consecutive hours). This rest period does not count against your 14-hour on duty clock. The other, separate rest period must be at least 2 consecutive hours long.
  • OOIDA does not believe the rigid “and/or 2” hour requirement is conducive to safety. Rather, a larger window for driver choice would improve safety.

30 minute mandatory rest break provision

  • The 8 hours are consecutive hours, so they include driving and all other time (including any breaks that are more than 30 minutes). The rules mandate drivers must stop driving CMVs after reaching 8 consecutive hours past the end of your last break of at least 30 consecutive minutes.
  • OOIDA does not believe a mandated 30 minute rest break is needed to promote safety.
  • OOIDA believes driver options should be expanded. More parking and flexible 14 hour rule options would promote safety by allowing a driver to rest when NEEDED rather than when mandated.
