What licehse required for 13000 pound trailer?

Answer 1

Can't really tell you without knowing the jurisdiction you're from. In the US, no special licensing would be required to tow that trailer unless the Gross Combined Weight Rating of the tow vehicle and the trailer together exceeded 26,000 lbs. So, if you were towing a trailer with a Gross Vehicle Weight Rating of 13,000 lbs. with a pickup which had a Gross Vehicle Weight Rating of 13,000 lbs, you have a Gross Combined Weight Rating of 26,000 lbs., and wouldn't require any upgraded license. Now if you were towing it with a Class 7 truck with a 33,000 lb. Gross Vehicle Weight Rating, you'd have a Gross Combined Weight Rating of 46,000 lbs, and special licensing would be required. Once it gets to that point, a Class A CDL is required, unless the vehicle falls under the exemptions for recreational vehicles, farm vehicles, emergency/first response vehicles, or military vehicles.
