Just A Question

Driving bobtail in a 2 axle tractor, is the speed limit 65 m ph or do I have to obey the 3 or more axle speed of 55 mph? I've asked several people and get different answers.

If you're below the required axle limit then you can go 65. I don't know why anyone would say otherwise. If you would be a 3 axle then you wouldn't be able to.

I was told by a couple of drivers that the tractor is still a commercial vehicle and therefore I have to keep it at 55

Indeed, but the sign says "axles" doesn't say anything about a commercial vehicle. This is just my opinion and I'm looking forward to more input.

A commercial vehicle is a commercial vehicle, be it 2,3,or 4 axles, be it bobtailing or pulling a trailer. I know what the signs say in some states. but others say TRUCKS..which is to mean commercial, farm, or retail trucks. But I'd like some other opinions on this also !!

What the sign says and what the law says can technically be two different things. They might mention axles on the sign but it may turn out that all commercial vehicles are subject to the speed limits.

For me personally, I was never sure so I never took the chance. I stuck with the truck speed limit regardless of whether I was bobtailing or not.
