What the Agricultural Exemption Does
The agricultural exemption is one of the broadest reliefs in the hours-of-service rules. Under 49 CFR 395.1(k)(1), the requirements of 49 CFR part 395 do not apply to drivers transporting agricultural commodities within a 150 air-mile radius from the source of the commodities, during the planting and harvesting periods determined by each State. Inside that radius and during those periods, the familiar driving and duty limits simply do not apply — and the driver is not required to use an ELD or keep a paper record of duty status for that operation.
This is genuinely an exemption from the rules, not a different set of rules. It exists because agricultural operations are intensely seasonal and time-sensitive: when a crop is ready or livestock must move, the work cannot wait for a reset period. Congress and FMCSA carved out a window where drivers operating close to the source can run without the standard HOS constraints. But the exemption is bounded on three sides — the commodity, the radius, and the season — and a driver who steps outside any of those boundaries is back under the full rules.
The Three Conditions
1. An agricultural commodity
The load must be an agricultural commodity as defined in 49 CFR 395.2 — agricultural products including horticultural products, livestock, bees, horses, fish used for food, and other commodities meeting the definition. To remain within the exemption when loaded at an intermediate point, the commodity must retain its original form and not be significantly changed by processing or packing.
2. Within a 150 air-mile radius of the source
The exemption covers transportation inside a 150 air-mile radius measured from the source — the point at which the commodity is loaded onto an unladen CMV. The radius is what matters, not the total trip distance: the relief applies to the portion of the trip within 150 air-miles of the source, regardless of how far the final destination is.
3. During a State planting or harvesting period
The exemption applies only during the planting and harvesting periods, which each State determines for its own jurisdiction. The carrier must operate within the dates its State has set. Outside the State-defined period, the exemption is unavailable and the normal HOS rules apply.
How the 150 Air-Mile Radius Works
The radius is the part operators most often misread. The 150 air-miles is measured as a straight-line radius from the source, not as driving miles, and it covers only the initial portion of the trip within that radius. FMCSA guidance is explicit: the exception is available for transportation up to 150 air-miles from the source, regardless of the distance between the source and the final destination or place of delivery. A driver can deliver a load 400 miles away and still have been exempt for the first 150 air-miles of that haul.
The flip side is just as important: once the driver operates beyond the 150 air-mile radius of the source, 49 CFR part 395 applies. The hours-of-service limits and the recordkeeping requirements kick in for the remainder of the trip. A driver who runs exempt to the edge of the radius and then keeps going must comply with HOS — and must account for the driving time on the non-exempt portion. The radius is a line the driver crosses, and the rules change the moment it is crossed.
The source can move with the commodity
The source is the point at which the commodity is loaded onto an unladen CMV — which means it is not always the farm. Under FMCSA guidance, the source can be an intermediate storage or handling location away from the original farm or field, as long as the commodity retains its original form and is not significantly changed by processing or packing. A new 150 air-mile radius is measured from each such loading point. This is why grain elevators and livestock yards can function as sources.
What Stays Within vs. Falls Outside
Within the Exemption
- Hauling a qualifying agricultural commodity loaded at the source
- Operating within 150 air-miles of that source
- Running during the State-defined planting or harvesting period
- Loading at an intermediate elevator or yard where the commodity keeps its original form
Outside the Exemption
- The portion of the trip beyond the 150 air-mile radius of the source
- Operating outside the State-defined planting or harvesting period
- Hauling a commodity significantly processed or changed from its original form
- Any operation that does not involve a qualifying agricultural commodity
The exemption is generous but easy to overrun
Because the relief is so broad inside the radius, drivers can lose track of where the line is — and the consequence of crossing it without switching to compliant operation is an hours-of-service violation. The safe practice is to know the air-mile distance from the source before dispatch, confirm the State planting/harvesting dates, and have a plan for compliant logging the moment the trip extends past 150 air-miles.
The Records That Support the Exemption
An exemption is only useful if the carrier can prove the operation qualified for it. Inside the 150 air-mile radius during a planting or harvesting period, the driver is not required to keep RODS or run an ELD for that operation — but that does not mean there is nothing to document. If an officer or auditor questions whether the exemption applied, the carrier has to be able to show the four things that establish it: the source location, the air-mile distance, the commodity type, and the State planting or harvesting dates that were in effect.
And the moment a trip extends beyond the radius, the recordkeeping obligation returns in full for the non-exempt portion. A carrier running mixed operations — some hauls fully within the radius, others crossing it — needs to keep clean records distinguishing the two, because part 395 applies to the non-exempt miles and the driver must account for that driving time.
Documentation That Supports an Ag-Exemption Claim
- Source records establishing where the commodity was loaded onto the empty CMV
- Trip and load documentation showing the commodity type and that it retained its original form
- The air-mile distance from the source to the point in question (to show the operation stayed within 150)
- The State planting or harvesting period dates in effect for that operation
- Compliant RODS for any portion of a trip that extended beyond the 150 air-mile radius
Where the Records Live: FileFlo
FileFlo is not an ELD and does not log duty status — your ELD or paper logs handle the record of duty status for non-exempt operation. FileFlo is the records and proof layer that holds the documentation supporting an agricultural-exemption claim: the source and load records, the commodity documentation, and the operating records that show a haul stayed within the 150 air-mile radius during a State planting or harvesting period. When the exemption is questioned, the carrier has to produce that proof — and FileFlo keeps it organized and exportable instead of scattered across dispatch notes and paperwork.
Key Takeaways
- HOS is suspended inside the radius. Within 150 air-miles of the source during a State planting/harvesting period, part 395 does not apply and no ELD or RODS is required for that operation (49 CFR 395.1(k)(1)).
- 150 air-miles is a straight-line radius from the source — and it applies regardless of how far away the final destination is.
- The source is the loading point. It can be the farm or an intermediate elevator/yard, as long as the commodity keeps its original form.
- Cross the radius and the rules return. Beyond 150 air-miles, part 395 applies for the rest of the trip.
- Document the qualifying conditions. Source, distance, commodity, and State dates are what prove the exemption if it is challenged.
Agricultural HOS Exemption: FAQ
Answers to common questions about the agricultural commodity hours-of-service exemption under 49 CFR 395.1(k).
Under 49 CFR 395.1(k)(1), the hours-of-service rules in 49 CFR part 395 do not apply to drivers transporting agricultural commodities within a 150 air-mile radius from the source of the commodities, during the planting and harvesting periods determined by each State. Within that radius and those periods, the HOS driving and duty limits do not apply and the driver is not required to use an ELD or keep paper RODS for that operation.
The exemption applies to transportation within a 150 air-mile radius from the source of the agricultural commodity, regardless of the distance between the source and the final destination. The HOS rules are suspended for the portion of the trip inside the 150 air-mile radius of the source. Once the driver crosses beyond that 150 air-mile radius, 49 CFR part 395 applies for the remainder of the trip — including the hours-of-service limits and recordkeeping.
Per FMCSA guidance on 49 CFR 395.1(k)(1), the source is the point at which an agricultural commodity is loaded onto an unladen commercial motor vehicle. The source can be the farm or field, or it can be an intermediate storage or handling location away from the original farm — provided the commodity retains its original form and is not significantly changed by processing or packing. The 150 air-mile radius is measured from that loading point.
No. The agricultural exemption applies only during the planting and harvesting periods, which each State determines for its own jurisdiction. Many States define these periods broadly, but they are set by the State and a carrier must operate within the dates its State has established. Outside the State-defined planting and harvesting period, the exemption is not available and the normal HOS rules apply.
Under the definition in 49 CFR 395.2, an agricultural commodity includes agricultural products such as horticultural products, livestock, bees, horses, fish used for food, and other commodities that meet the regulatory definition. The commodity must retain its original form to remain within the exemption when loaded at an intermediate source. Commodities that have been significantly processed or changed in form may no longer qualify.
Within the 150 air-mile radius of the source during a planting or harvesting period, the driver is not required to keep RODS or use an ELD for that operation. But a carrier still has to be able to show the operation actually qualified — records that establish the source location, the air-mile distance, the commodity type, and the State planting/harvesting dates are what support the exemption if it is questioned. Once the driver operates beyond the 150 air-mile radius, part 395 applies and the driver must keep records for the non-exempt portion.
Prove the Exemption When It Is Questioned
FileFlo is the records and proof layer for FMCSA compliance — it is not an ELD and does not log duty status. It holds the source records, commodity documentation, and operating records that support an agricultural-exemption claim, plus compliant records for any miles beyond the 150 air-mile radius. When an officer or auditor asks you to prove the operation qualified, export the proof in minutes.
