Big truck, semi, 18 wheeler.
Semi Truck oer 18 Wheeler (Eighteen Wheeler)
The tractor weighs 20,000 pounds, the trailer weighs whatever it weighs, and the maximum weight of a loaded tractor trailer with one trailer is 80,000 pounds.
Start by dropping your trailer. You will notice there are wheels on only one end. A trailer like that is a "semitrailer." A "full trailer" has wheels at both ends. The official name is a "tractor-semitrailer," shortened to "semi."
Any vehicle towing a trailer or other vehicle is, in essence, a tractor. If the dump truck is towing another vehicle (trailer, etc.), then it is a truck tractor. If it isn't, then it's just a straight truck.
$70 for a 5 axle tractor trailer
I would have to say no. I have a tractor that is insured the only thing that is insured is just that the tractor (fire theft etc). Although You can get your trailer insured just as you can an ATV horse trailer car truck if you had a policy for it. your tractor insurance will not help with the trailer.
