18 Wheeler Insurance Explained – What You Need to Know

18 wheeler trucks, also known as semi-trucks, big rigs, or tractor-trailers are the backbone of the American economy. These large commercial vehicles transport goods and products across the country every day. However, driving an 18 wheeler can be risky, not only for the driver but also for the cargo and other vehicles on the road. That’s why it’s crucial to have the right insurance coverage to protect yourself and your business.

What is 18 Wheeler Insurance?

18 wheeler insurance is a type of commercial truck insurance that protects the owner-operator, a small fleet owner or a large motor carrier from financial loss in case of an accident, theft, or damage to the truck and its cargo. It’s mandatory by law to have a minimum level of insurance coverage for commercial vehicles, including 18 wheelers.

The coverage typically includes:

Insurance Coverage

Cargo Insurance
Covers the goods or products being transported in case of damage, theft or loss.
Bobtail Insurance
Covers the truck and trailer when they’re being driven without the trailer or cargo.
Non-Trucking Liability Insurance
Covers liability when the truck is being operated for non-business purposes such as going to a mechanic or driving home after work.
