Semi Truck Insurance Explained
A semi truck — also called an 18-wheeler or tractor-trailer — is one of the largest vehicles on the road. Insuring one requires specialized knowledge that general auto insurers often lack.

Required by law (FMCSA):
- Primary Liability: Minimum $750,000 for general freight; up to $5,000,000 for hazmat
Highly recommended:
- Physical Damage (collision + comprehensive)
- Motor Truck Cargo Insurance
- General Liability
- Trailer Interchange
