HOS Trip Planning
34-Hour Restart Trip Planning
How to plan a restart around parking, services, and the next dispatch.
By Dale Connors, Founding Editor · Content reviewed quarterly against FMCSA guidance and official state resources. A restart is not only a clock reset. It is also a place decision: parking security, food, showers, repair access, laundry, weather exposure, and whether the truck can legally remain there.
The best restart location supports the next load instead of stranding the driver away from freight, fuel, or repair options.
Under standard FMCSA property-carrier rules, a 34-hour restart resets the 60 or 70-hour weekly on-duty limit after at least 34 consecutive hours off duty. The exact requirements depend on operation type and current FMCSA guidance. The planning implication is straightforward: the restart location needs to support a 34+ hour stay, not just an overnight stop.
Choosing a restart location only based on where the driver currently sits — rather than where the driver needs to be for the next load — is one of the most expensive planning errors in long-haul operations. A driver who restarts at a location far from the next freight area, without adequate services, or without confirmed permission for an extended stay, will pay for that decision in recovery time, additional fuel, and driver fatigue.
A planned restart — one that the driver and dispatcher anticipated days before the weekly limit was reached — is a completely different event from an unplanned restart forced by a surprise clock situation. The planned version allows the driver to be positioned well, the dispatcher to have a load ready, and the truck to be serviced during the downtime. The unplanned version creates all the same downtime with none of the operational benefit.
Restart location criteria
| Factor | Why it matters for a 34-hour stay | Red flag |
|---|---|---|
| Overnight permission and time limits | A 34-hour stay requires confirmed permission, not just overnight tolerance | Property restricts stays to 8–12 hours |
| Services for 1.5+ days | Driver needs food, showers, laundry access for a multi-day stay | No services within walking distance or services close at night |
| Security | Cargo and equipment exposure increases with a longer stay | No lighting, no attendance, high-traffic area near the lot |
| Position for next load | Starting from the wrong location adds hours and fuel to the next trip | Restart location is far from likely next freight areas for this driver |
| Weather exposure | A restart during a weather event needs a safe location to wait | Exposed location in a corridor with active winter or severe weather |
Planning moves that help
- Confirm the location explicitly allows a 34-hour or longer stay without time-limit enforcement.
- Choose a place with adequate services for the full break: food, shower, laundry, and any needed maintenance.
- Plan how the driver will depart on the next dispatch without immediately burning time or fuel on a long recovery drive.
- Keep ELD and log status clear through the restart period — the restart should be recorded correctly from the first hour.
- Consider weather, security, and cargo requirements for a multi-day stay.
- Identify a backup restart location before committing the truck to a position where no alternatives exist.
How to track cumulative hours to anticipate the restart
The 34-hour restart is triggered by the 60 or 70-hour weekly on-duty limit — whichever applies to the operation. A driver on a 7-consecutive-day schedule has a 60-hour cumulative limit. A driver on an 8-consecutive-day schedule has a 70-hour limit. The limit is cumulative across the applicable period, not a daily reset.
Anticipating the restart requires tracking cumulative hours throughout the week, not only when the limit is close. A driver and dispatcher who check cumulative hours at the start of each load-planning conversation can see the restart coming 2-3 days in advance and position the truck accordingly. A driver and dispatcher who check cumulative hours only when the driver is already close to the limit will be choosing a restart location under time pressure at the worst possible moment.
The ELD tracks cumulative hours automatically and shows the driver's remaining weekly time. The planning conversation should include the cumulative hour status — not just the daily clock — when building any multi-day load plan. A load that looks feasible on daily hours alone may not be feasible when the weekly limit is also considered.
Common planning mistake
The common mistake is choosing a restart location based only on where the truck currently sits rather than where the truck needs to be for the next load. A restart that leaves the driver far from freight, repair, or fueling options adds recovery time after the clock resets.
A second common mistake is treating a restart as an unplanned break — stopping wherever is convenient when the weekly limit approaches. A planned restart, positioned correctly relative to the next load, is a competitive advantage. An unplanned restart that strands the driver at a random location is a cost.
Driver / dispatcher / owner-operator angle
- Driver: think through food, sleep quality, laundry, shower, and any service needs before committing to the restart location — you are going to be there for at least 34 hours.
- Dispatcher: where the driver restarts affects the next load acceptance, fuel cost, and departure readiness. Build the restart location into the load planning conversation, not just the hours calculation.
- Owner-operator: a restart at a well-positioned location with good services and security is part of operating cost. An unplanned restart at a poor location adds hidden cost to the week.
What to check before relying on this
- Whether the location explicitly allows a full 34-hour stay without time limits or overnight restrictions.
- Service quality: food, shower, security, and any required maintenance or repair availability.
- Distance to the likely next freight area and the fuel cost and time of the departure drive.
- ELD and log status to ensure the restart is recorded correctly from the beginning.
- Current FMCSA guidance on 34-hour restart requirements and any operation-specific conditions.
Backup plan
Identify two restart options in the area — one preferred, one acceptable — before committing the truck to a position where no alternatives exist.
How does the 34-hour restart work for truck drivers?
Under standard FMCSA property-carrier HOS rules, a driver can reset the 60 or 70-hour cumulative weekly on-duty limit by taking at least 34 consecutive hours off duty. After the 34-hour period, the weekly on-duty clock starts fresh. The exact requirements, including any specific time-of-day conditions that may apply, depend on current FMCSA rules and the driver's operation type. Verify with current FMCSA guidance, the ELD, and carrier policy.
Where should a truck driver plan a 34-hour restart?
The best restart location balances four factors: explicit permission for a multi-day stay, adequate services for 34+ hours (food, shower, security), reasonable position relative to the next likely load area, and weather and cargo security considerations. A location that scores well on all four factors makes the restart productive rather than just a mandatory wait.
Should a 34-hour restart be planned in advance or taken opportunistically?
Planned in advance produces better outcomes. A driver and dispatcher who anticipate when the weekly limit will become the binding constraint can choose a restart location that serves the next load, rather than stopping wherever happens to be convenient when the clock runs out. Proactive tracking of cumulative weekly hours — not just daily limits — is what makes advance restart planning possible.
