What It Costs
Most California contractors pay $1,200-$3,000 annually per vehicle for commercial auto insurance.
Adding 'Hired & Non-Owned' coverage protects your business if an employee gets into an accident while driving their personal truck to pick up materials for you.
CA Rules You Need to Know
Is commercial auto insurance contractors required in California?
Yes, California law requires all vehicles on the road to carry liability insurance. If the vehicle is owned by the business or used primarily for business, it must be a commercial policy.
What limits do most require?
Most commercial contracts require a $1,000,000 Combined Single Limit (CSL) for commercial auto liability.
What happens if I let it lapse mid-project?
A lapse means your vehicles cannot legally be driven. If an accident occurs, the business is fully liable for damages, which can easily bankrupt a contracting firm.
