Hazmat and short haul exemption

NO, you don't need to log under the air mile exemption even if hazmat as long as you do not work over 12 hrs.

 

And to specify a bit more...
Hazmat does not come into play when talking about the time card exception.
All that matters is distance (115 miles) and time (12 hours for start to finish) and I believe one other that I can't remember...

 

My daily trip is 125 miles.

We have a dairy that's 160 miles.

Both are slightly under the 100 mile radius.

 

I don't know how anyone can come up with 115 miles for 100 air miles. There are many journeys that are farther then 115 miles and still under the 100 radius.

 

In legal parlance an air mile is the same as a nautical mile. A nautical mile is 1.1508 miles, hence the 115 miles people talk about. And yes, you are correct it is a 115 (land mile) radius. And one can do a lot of driving in that 230 mile wide circle. (Radius being 1/2 the diameter of a circle)

I honestly don't think the regulators meant air mile = nautical mile. I think they were going for 100 miles as the bird flies. But they used well defined legal jargon in a legal regulation so we get a few more miles out of it.

 

There's more to the exemption than just keeping the trip under a 100 air miles. You can find what you need in the FMCSR's 395.1 (e). And a 100 air miles is in nautical miles but the just of the rule is a 100 air miles which is measured in a straight line from point A to point B.

 

That is a 100 air mile radius, stick a pin in your starting location and draw a circle around that point at 114.63 statute miles. As long as you stay in that circle and return to home base within 12 consecutive hours AND have 10 hours of before the next shift you are golden. Your company is required to keep a time record showing that you meet the 12 consecutive hours...

No point a to b you can ping pong around inside that circle all day...
