150 Air-Mile Agricultural HOS Exemption
A while back I came across a topic that my common sense simply refused to accept at first.
I read it. Checked the regulations. Read it again.
And my gut kept saying: wait a minute.
We’re talking about the Agricultural Exemption from Hours of Service regulations.
Everything is legal. Everything is in the rulebook.
But does legal automatically mean safe?
Read this and decide for yourself.
What Is the HOS Agricultural Exemption?
FMCSA regulations allow drivers to transport unprocessed agricultural commodities without keeping a logbook — within a 150 air-mile radius from the source of loading.
No drive time recording required. No hour limits to track. The HOS clock simply… doesn’t run.
Legally.
What Qualifies for This Exemption?
The products must be:
- Unprocessed
- Not preserved
- Not packaged
- Not manufactured
Examples:
- Fresh fruits and vegetables
- Watermelons straight from the field
- Flowers
- Live trees and Christmas trees
- Animal feed
- Livestock
- Other agricultural commodities that spoil quickly
Where Is This Written?
Two places to check:
- 49 CFR 395.2 – definition of “agricultural commodity”
- 49 CFR 395.1(k) – Agricultural Operations Exemption
It’s in black and white. Legal. In effect.
How the 150 Air-Mile Radius Works
Picture a driver hauling beets from a field to a processing facility.
Straight-line distance: 80 miles. He drives back and forth. All day long.
No logbook required. Drive time doesn’t count. He can keep going without stopping.
As long as he stays within those 150 miles.
And This Is Where It Gets Concerning
Now picture this.
A driver hauls beets locally for 12 hours. All within the 150-mile radius. All completely legal.
The last load of the day goes across the country.
He crosses the 150-mile boundary.
At that moment — he activates his logbook.
The HOS clock starts from zero.
Technically, he has a full 11 hours of driving ahead of him.
Legal? Yes. But that driver has already been behind the wheel for 12 hours.
And that’s where my common sense said: stop.
Does Time Inside the Exempt Zone Count Toward HOS?
Officially — no.
Time spent transporting agricultural commodities within the 150-mile radius:
- Does not count toward daily driving limits
- Does not count toward weekly on-duty limits
- Does not appear in the logbook
Technically the driver starts the OTR trip with a clean clock.
And that is exactly the part every driver and every carrier should think hard about.
How to Log It in Your ELD
FMCSA points to two methods:
Option 1 – Personal Conveyance with annotation: Select Personal Conveyance and add a note: “Agricultural commodity operations – 150 air-mile radius exemption.”
Option 2 – Log out of ELD: FMCSA also indicates the option of logging out of the ELD and later annotating the unassigned drive time as agricultural exemption.
Personally — I would not recommend the second option.
Remember: the burden of proof is on you to demonstrate that you were authorized to use this exemption. Document everything.
Drivers should check with their ELD provider or Safety Department to see whether their system offers a dedicated Agricultural Exemption option instead of using Personal Conveyance.
Practical Guidance for Drivers and Carriers
A few things worth knowing before you use this exemption:
- You do not need to activate your logbook when loading, for example, a full truck of watermelons directly from the field — as long as you stay within the 150-mile radius
- The exemption also applies when deadheading to the loading location within the same zone
- Always check with your Safety Department whether your ELD system has a dedicated Agricultural Exemption option
- Many modern ELD systems have this feature built in — ask your carrier
My Take – Legal Doesn't Always Mean Safe
I’m not questioning the regulation.
This exemption exists for a real reason — agricultural products spoil, seasonal work operates on its own timeline, and I understand the logic behind this rule.
But as someone who works in road safety — I can’t stay quiet about this:
A driver who spent 12 hours behind the wheel hauling back and forth across fields is a tired driver.
And that tired driver legally has a full 11-hour OTR trip ahead of them.
Every driver and every carrier must use professional judgment when applying this exemption.
The law gives you the option. You decide whether to use it.
