The agricultural HOS exemption under 49 CFR 395.1(k) allows qualifying drivers transporting agricultural commodities or farm supplies to operate beyond standard HOS limits during the planting and harvest period. The driver must be operating within 150 air miles of the source of the commodities. The planting and harvest period dates are set by each state. Outside the designated window, standard HOS rules apply. Verify the specific dates and conditions for each state where your drivers operate through FMCSA's published state-by-state listing.
Agricultural haulers get asked about this exemption at inspections and audits more than you would expect. The reason is that it is commonly misunderstood. Carriers assume it is an industry-wide carve-out. It is not. There are specific conditions that have to be met, and carriers that cannot document those conditions do not get the benefit of the exemption at a roadside stop.
- Carriers hauling agricultural commodities or farm supplies within a qualifying radius.
- Owner operators doing seasonal ag work who want to know whether and when standard HOS rules kick back in.
- Fleet managers overseeing drivers who operate in multiple states with different seasonal windows.
- Carriers whose drivers mix ag and non-ag loads on the same day or week.
The three conditions that must all be true
For the 49 CFR 395.1(k) exemption to apply, three things must be true at the same time.
| Condition | What it means | Common misconception |
|---|---|---|
| Agricultural commodity or farm supply | The load must be an agricultural commodity (crops, livestock, bees, horticultural goods, forest products, seafood, or nursery goods) or supplies to be used in agricultural production | Any food or rural product qualifies. It does not. Processed food, manufactured goods, and non-farm materials do not qualify. |
| Within 150 air miles of the source | The driver must be within 150 straight-line miles of the agricultural operation or original source of the commodity | 150 road miles on the odometer. Air miles is straight-line distance. |
| During the planting and harvest period | Must fall within the planting and harvest window designated by the state where the driver is operating | The exemption applies year-round for ag haulers. It applies only during the state-designated window. |
If any one of these three conditions is not met, standard HOS rules apply for that day. A driver who qualifies Monday through Saturday but hauls a non-qualifying load on Sunday is back under standard HOS requirements on Sunday.
What the exemption actually changes
When all three conditions are met, the driver is exempt from the HOS requirements in 49 CFR Part 395 during the operation. This means the standard driving limits, on-duty limits, and rest requirements do not apply during qualifying trips. But the exemption has limits of its own.
The exemption applies during the qualifying trip. It does not erase accumulated hours from earlier non-qualifying work in the same day or week. If a driver spent the morning doing non-ag hauling under standard HOS, that time still counts when reviewing whether the driver was within limits during the non-exempt portion of the day.
What still applies during the exemption
- The driver must still be medically certified and hold a valid CDL if required for the vehicle and load.
- The vehicle must still pass inspection. The ag exemption does not waive vehicle maintenance requirements.
- Drug and alcohol testing requirements still apply.
- The driver cannot be impaired. HOS exemption is not an exemption from impairment rules.
- Non-qualifying work done during the same week still counts toward HOS limits when the driver returns to non-exempt operations.
ELD requirements and the agricultural operation
There is a separate exemption from the ELD mandate for certain agricultural operations. Drivers who qualify under 49 CFR 395.1(k) for the HOS exemption may also qualify for relief from ELD requirements during qualifying trips. However, the two exemptions are not identical in scope. Some agricultural operations that qualify for HOS relief may still require ELD documentation under state-specific rules or the specific scope of the FMCSA exemption.
Verify the current ELD exemption status for your specific agricultural operation against FMCSA's guidance and any state-specific requirements where drivers operate. Do not assume ELD is automatically waived because the load qualifies for HOS relief.
Multi-state operations and state-by-state windows
This is where agricultural carriers frequently run into trouble. Each state sets its own planting and harvest window dates. A driver crossing state lines during a single run may enter a state where the window has not opened yet, or one where it has already closed.
FMCSA publishes a state-by-state listing of agricultural exemption periods. Before assuming the exemption applies in any given state, check that state's designated window. A carrier with drivers covering multiple states needs to know the window dates for each state, not just the home state.
Scenarios: when it applies and when it does not
| Scenario | Exemption applies? | Why |
|---|---|---|
| Hauling grain from a farm within 80 air miles during state harvest window | Yes, if all three conditions are met | Agricultural commodity, within 150 air miles, within designated window |
| Hauling fertilizer to a farm during harvest window within 140 air miles | Yes, if conditions are verified | Farm supply qualifies under the exemption |
| Hauling grain during harvest window but 180 air miles from the farm | No | Outside 150 air-mile radius |
| Hauling grain in a state where the harvest window has not opened yet | No | Outside designated planting and harvest period for that state |
| Hauling processed canned goods from a food distributor | No | Processed food from a distributor is not an agricultural commodity at its source |
| Driver hauled ag load in the morning (exempt), then hauls general freight in the afternoon | Only during qualifying ag trip | Non-qualifying freight is back under standard HOS. Morning hours are not erased. |
What carriers should document
Carriers that operate under this exemption should be able to show, at a roadside inspection or audit, that the operation actually qualified. That means having records of:
- The commodity or farm supply being transported.
- The source of the commodity and the air-mile distance from that source.
- The state of operation and the designated planting and harvest dates for that state.
- The dates the driver operated under the exemption.
If ELD is still required during qualifying operations, ELD records apply. If the ELD exemption also applies, retain documentation of why ELD was not required. Inspectors do ask. "We're an ag carrier" is not documentation.
The free Daily Logbook Audit Checklist covers duty status documentation and what to check in daily records for carriers managing exempt and non-exempt operations on the same fleet.
The ag exemption trips up carriers in two ways. First, they assume it applies to their operation without checking the state window dates or the 150 air-mile condition. Second, they keep no records to show it applies. If a driver gets stopped during what they believe is an exempt trip and cannot document that it qualifies, they have a problem. The exemption is not a safe harbor just because your load is grain. Document it like it would be questioned, because at some point it probably will be.

The agricultural HOS exemption under 49 CFR 395.1(k) allows qualifying drivers transporting agricultural commodities or farm supplies within 150 air miles of the source to operate beyond standard HOS limits during the state-designated planting and harvest period. All three conditions must be met. Carriers must verify the specific dates and conditions for each state where drivers operate.
No. The exemption applies only to qualifying operations: transporting agricultural commodities or farm supplies, within 150 air miles of the source, during the state-designated planting and harvest period. Drivers hauling other freight, operating outside that radius, or working outside the designated seasonal window must follow standard HOS rules.
There is a separate ELD exemption for certain agricultural operations. Drivers who qualify under 49 CFR 395.1(k) may also qualify for the agricultural ELD exemption. But the exemptions are not automatic for all agricultural haulers. Verify your specific operation against current FMCSA rules and state-specific requirements to confirm whether ELD is still required.
Each state designates its own planting and harvest period dates and may impose additional conditions. FMCSA provides a state-by-state listing of agricultural exemption periods. Carriers must check the specific dates for each state where qualifying drivers operate.
Even when the HOS exemption applies, carriers should document that the operation qualifies: the commodity being transported, the radius from the source, the dates of operation relative to the state-designated window, and the state in which the driver operated. If ELD is still required, ELD records must be maintained. If ELD is exempt, retain records showing the basis for that exemption.
