Business Insurance

Commercial Auto Insurance

Commercial auto insurance covers vehicles owned or regularly used by a business, providing liability protection and physical damage coverage that personal auto policies explicitly exclude for business use.

Definition

Commercial auto insurance provides liability coverage for bodily injury and property damage caused by vehicles used in business, as well as collision and comprehensive coverage for the vehicles themselves. A single commercial vehicle for a small contractor might cost $1,200–$3,500/year, while a fleet of 10 delivery trucks could run $30,000–$80,000/year depending on driver records and cargo type. Personal auto policies contain exclusions for vehicles used regularly for business purposes — a photographer using their personal SUV to transport equipment to shoots would have a claim denied under their personal policy. Commercial auto underwriters scrutinize driver MVR (motor vehicle records) heavily; a driver with DUI convictions can make a vehicle uninsurable in standard markets. Businesses that allow employees to use personal vehicles for work errands should add hired and non-owned auto coverage to their commercial auto or general liability policy. Fleet telematics programs that track driver behavior can reduce premiums by 5–15% with participating insurers.
