The world of commercial driving is one that is complex and constantly evolving. The industry currently employs over 3.5 million drivers, driving 15.5 million trucks, and delivering over $600 billion worth of goods.

That means that there is a colossal amount money, goods, vehicles, and people at risk every day. The importance of commercial truck insurance can, therefore, not be undervalued.

Not to mention, it's an industry almost as highly regulated as the trucking industry itself. Financial responsibility for drivers and motor carriers becomes a safety issue for the general public--at a much higher degree than typical auto insurance as well.

It is important to understand the different types of truck insurance available and the differences between them--you might find that it's easy to carry both too much insurance or not enough. Knowing the right mix of policies can help you save annual costs.

Primary Liability

One of the most basic forms of truck insurance. It covers drivers employed by trucking companies from third party property damage and injury costs. It may cover independent operators working on a contractual basis, as well. This is the least amount of coverage required by law to operate a commercial truck in the United States.

Physical Damage Coverage

This covers damage incurred in an accident whether you are at fault or not. The coverage can extend to cover the cost of repair or replacement for instances such as fires or vandalism, also. It is a good idea to purchase these policies in addition to your primary liability.

Trailer Interchange

Companies and independents who participate in trailer interchange agreements are encouraged to purchase these policies to protect against loss or damages to trailers and cargo that are not their property.

Non-Trucking Liability

This type of coverage is intended for independent owner/operators to keep their trucks insured when not actively under the umbrella of their contracted employer's coverage. There are different types of non-trucking liability, such as bobtail insurance.
