DOT rules and regulations apply to all vehicles, and their drivers, used in interstate commerce with a Gross Vehicle Weight Rating (GWVR) of 10,001 pounds or more. The GVWR of a vehicle is a value assigned by the manufacturer. It is how much he thinks the vehicle can safely carry, including the weight of the vehicle. It is not the weight of the vehicle, or the weight at which you register the vehicle. The GVWR is commonly found on a metal plate on the inside of the door.
Power units are not the only vehicles with GVWRâ€™s; trailers have them as well. When determining the GWVR of a combination unit, you must add the GVWR of the truck to that of the trailer. If it is 10,001 pounds or more, and goes across state lines, it is subject to the rules.
It doesnâ€™t take much to come up with a 10,001 pound or more rig. A Â¾ ton pickup probably has a GVWR of around 8,000 pounds. A one ton pickup is close to 10,000 pounds, if not over. If you pull any sort of trailer with these type of pickups, you are very likely over 10,001 pounds for the combination, thus making you subject to the rules.
A vehicle, which has a GVWR of over 10,001 pounds, but not over 26,001 pounds, which is a CDL vehicle, is subject to all of the same rules as a CDL vehicle, except for drug and alcohol testing. This means if you have a one ton pickup, pulling a kiddie ride, going state to state on your route, that driver must fill out logbook. He must have a medical card. The truck and the trailer must have an annual inspection. The truck must have a fire extinguisher and reflectors. The truck must have a USDOT number on it.
Trucks being used for non-commercial purposes are not subject to the rules. For example, you use your one ton truck to pull a trailer loaded with construction equipment for your job: subject to the rules. You use your one ton truck to pull a trailer with some ATVâ€™s on them so you can so four-wheeling on the weekend: not subject.
Undoubtedly, you are thinking, â€œhey, I see those type of hot-shot combinations all the time on the highway, and none of these guys have USDOT numbers on themâ€. Theyâ€™re probably violating the law. Most DOT cops donâ€™t bother with the smaller combinations. However, if a DOT cop wants to write some easy tickets, all he needs to find is a one ton pulling a trailer for a business purpose with out-of-state plates, and no USDOT number on it. It just a question of if the officer wants to spend the time writing all those tickets that day. If you get stopped in one of these smaller rigs, and your driver is not adhering to any of the rules, it can be several hundreds of dollars in tickets. You should review their equipment and determine if they have any of the 10,001 â€“ 26,001 pound GVWR vehicles. These vehicles and their drivers are subject to nearly the same rules as the big trucks!
