Things to know before buying auto coverage
- Personal auto insurers can deny a claim the moment they learn the trip was for business.
- Multi-vehicle discounts of 5 to 15 percent are common but not modeled in this estimate.
- Hired and non-owned auto coverage protects you when employees drive their own cars for work.
Why your personal auto policy is not enough
Personal auto policies are written for commuting and personal errands, not business operations. The moment you use a vehicle to haul equipment, visit clients, make deliveries, or transport employees, most personal carriers consider the trip commercial and will deny a claim. That gap is more expensive than the premium you save by skipping a commercial policy.
Commercial auto insurance covers liability for accidents involving your business vehicles, physical damage to the vehicles themselves, and hired or non-owned autos when employees use their own cars for work. Premium drivers include each driver's record, vehicle age and weight class, annual mileage, and state regulations. States like Louisiana, Michigan, and New York carry the highest base rates; rural states in the Great Plains run considerably lower. A fleet of even two vehicles warrants getting at least three competing quotes. For broader protection, consider pairing commercial auto with a general liability policy or bundling into a Business Owner's Policy where available.
