What Commercial Auto Covers for Plumbers in Washington

Commercial Auto Insurance for plumbers in Washington covers liability, collision, and physical damage for business-owned or business-used vehicles. This includes company cars, vans, and trucks used to travel to job sites, transport equipment, and conduct business. For example, if you are involved in an accident while driving to a job site in Spokane, Commercial Auto Insurance will cover the damages to your vehicle and any injuries or property damage caused to others. Additionally, it will cover physical damage to your vehicle, such as theft or vandalism, and provide liability coverage in case you are sued. However, Commercial Auto Insurance does not cover tools and equipment, which are typically covered under a separate policy, such as Tools & Equipment Insurance. You should note that General Liability Insurance, which is often required by clients, does not cover vehicles, making Commercial Auto Insurance a necessary addition to your insurance portfolio.
