What Commercial Auto Covers for Plumbers in Missouri

Commercial Auto Insurance covers business-owned vehicles with liability, collision, and physical damage. This means that if you're involved in an accident while driving a company vehicle, your insurance will pay for damages to the other party's vehicle, as well as any medical expenses. It also covers damage to your own vehicle, regardless of who's at fault. However, it does not cover tools or equipment stored in the vehicle, which would be covered under a separate Tools & Equipment policy. For example, if you're driving to a job site in Kansas City and get into an accident, your Commercial Auto Insurance would cover the damages. Additionally, if your vehicle is stolen or vandalized, your insurance would cover the cost of repairs or replacement.

Do Plumbers in Missouri Need Commercial Auto?

Most general contractors, commercial property managers, and municipal clients in Missouri require plumbers to carry Commercial Auto Insurance with at least $1 million in liability coverage. This is because they want to ensure that they're protected in case something goes wrong on the job site. Additionally, having Commercial Auto Insurance can give you a competitive edge when bidding on jobs, as it shows that you're a responsible and professional business owner. While it may not be legally required, it's strongly recommended for any plumber who uses vehicles for work. In fact, many clients and contractors will not hire a plumber who doesn't have Commercial Auto Insurance. For example, a plumber in St. Louis who wants to work with a large commercial property manager may need to provide proof of Commercial Auto Insurance before being hired.

A Real Commercial Auto Claim a Plumber Could Face

Springfield Plumbing was working on a job site in Springfield, Missouri, when one of their employees was involved in an accident while driving a company van. The employee was at fault, and the other party's vehicle was severely damaged. The other party also suffered injuries and had to be taken to the hospital. Commercial Auto Insurance covered the cost of damages to the other party's vehicle, as well as their medical expenses. The insurance also covered the cost of repairs to the company van. In total, the claim was worth $50,000, but the plumber's insurance covered the entire amount, leaving them with no out-of-pocket expenses. The plumber was able to continue working on the job site without interruption, and the client was satisfied with the work.

What Commercial Auto Costs for Plumbers in Missouri

The cost of Commercial Auto Insurance for plumbers in Missouri varies from $100-$310/month, depending on factors like revenue, payroll, and coverage limits. The cost is also affected by the type of vehicles being insured, as well as the driving records of the employees who will be operating them. For example, a plumber with a fleet of vehicles and a high revenue may pay more for Commercial Auto Insurance than a smaller plumbing business with only one or two vehicles. Additionally, the cost of Commercial Auto Insurance in Missouri is also affected by the state's risk environment, including tornado risk and flooding along the Missouri and Mississippi Rivers. To lower your premium, you can consider increasing your deductible, improving your driving record, or bundling your Commercial Auto Insurance with other policies. It's also important to shop around and compare quotes from different insurance providers to find the best rate for your business.

Frequently asked questions

Will my Commercial Auto premium jump after one claim?

Yes, it may increase. The amount of the increase will depend on the severity of the claim and your overall claims history. If you have a history of safe driving and few claims, your premium may not increase as much as it would if you have a history of accidents or claims. Additionally, some insurance providers offer accident forgiveness programs, which can help keep your premium from increasing after a claim.

Can I get a COI same-day for a client?

Yes, it's possible. Many insurance providers offer same-day COI issuance, especially if you're working with an agent who has experience with Commercial Auto Insurance. However, it's always best to plan ahead and request your COI as soon as possible, in case there are any delays or issues with the issuance process. Some insurance providers may also offer online COI issuance, which can make it easier to get the certificate you need quickly.

Does a sole proprietor need Commercial Auto?

Yes, if you use a vehicle for business purposes. Even if you're a sole proprietor, you'll still need Commercial Auto Insurance to protect yourself and your business in the event of an accident or other loss. This is because personal auto insurance policies typically don't cover business use, and you could be left with significant out-of-pocket expenses if you're involved in an accident while driving for work. Additionally, many clients and contractors require sole proprietors to have Commercial Auto Insurance before hiring them for a job.

What's not covered by Commercial Auto Insurance?

Commercial Auto Insurance does not cover tools or equipment stored in the vehicle, which would be covered under a separate Tools & Equipment policy. It also does not cover intentional damage or theft by an employee, which would be covered under a separate Crime policy. Additionally, Commercial Auto Insurance may not cover damage to vehicles that are not owned or leased by the business, such as employee-owned vehicles. It's always best to review your policy carefully to understand what is and isn't covered.

Can I cancel my Commercial Auto policy at any time?

Yes, but you may be subject to a penalty or fee. It's always best to review your policy carefully before canceling, as you may be required to provide notice or pay a cancellation fee. Additionally, canceling your Commercial Auto policy could leave you without coverage, which could put your business at risk in the event of an accident or other loss. It's always best to work with an insurance agent who can help you understand your options and make the best decision for your business.
