What happens if you are overweight?

Depends on the state you are in when caught. Some are fix it states, meaning you must get load legal before leaving the scale others they just fine you and send you down the road.

3k over doesn't seem like much but to some states it can be out of service, others it won't even get any attention.

If I read this correctly, Oklahoma is an unload state at the discretion of the officer.

In fuel it will be cheaper to two trip it than to pay the fine for violating weights plus any potential lets take a exam of you and your truck inspection that follows.

Some states write tickets to company others to the driver. 3000 pounds at even .15 a pound for axle 500 give or take dollars. You will probaby do two trips and get it done without the hassle. The axle rate I gave you dates to the 80's so god only knows what they are now.

 

A quick look at the Texas Code, overweight on axle but not gross ranges from $250-$1000, can be less at a Judges discretion. Oklahoma is similar fine range but appears to be a state that can make you unload on the spot to become legal, which means another company may have to come haul away the extra piece of equipment?

 

Plenty of back roads from OK to TX. Just don't roll aross a scale...

 

In Texas as company owner the overweight can go on your driver license, if just a employee it isn't attached to your license.

For 3k pounds I would just run it, do my best to avoid a scale.

 

No easy scenic route?
