I been driving for 3 yrs OTR. I know about tandem spacing for 53ft trucks, depending on state 40 to 45 inches or less. My question is what if you have a 48Ft trailer and driving across varies states is there DOT laws that govern weight of 80, 000 LBS. trailer and distribution of GWT on trailer when you are hauling 48ft trailer.

OTR:

Over The Road

OTR driving normally means you'll be hauling freight to various customers throughout your company's hauling region. It often entails being gone from home for two to three weeks at a time.

Tandem:

Tandem Axles

A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".

DOT:

Department Of Transportation

A department of the federal executive branch responsible for the national highways and for railroad and airline safety. It also manages Amtrak, the national railroad system, and the Coast Guard.

State and Federal DOT Officers are responsible for commercial vehicle enforcement. "The truck police" you could call them.

Im assuming you meant FEET and not inches, but absolutely there are weight limitations on ANY commercial vehicles trailer's axles regardless of the length. If you've been driving for 3 years OTR , I would certainly hope you know the max axle weights.

Are you asking about split axils or a closed random? Or are you asking about king pin settings?
