What Commercial Auto Covers for Plumbers in Illinois

Commercial Auto Insurance covers vehicles used for business, including liability, collision, and physical damage for company cars, vans, and trucks. This coverage pays for damages and injuries caused by your company vehicles, as well as damages to your vehicles themselves. For example, if one of your plumbers is involved in an accident while driving a company van to a job site in Joliet, Commercial Auto Insurance would cover the costs of repairs, medical expenses, and potential lawsuits. However, it does not cover tools and equipment, which requires a separate policy.

Do Plumbers in Illinois Need Commercial Auto?

While Commercial Auto Insurance is not legally required for plumbers in Illinois, it is often contractually required by clients, landlords, and contractors. Most general contractors, commercial property managers, and municipal clients require plumbers to carry at least $1 million in general liability coverage and list them as an additional insured. Without Commercial Auto Insurance, you risk being unable to secure contracts and facing financial devastation in the event of an accident. In practice, this means that plumbers in Illinois who want to work with major clients in Chicago and Aurora need to have Commercial Auto Insurance to be considered for projects.

A Real Commercial Auto Claim a Plumber Could Face

ABC Plumbing in Chicago was working on a large construction project when one of their company trucks slid on ice and crashed into a pedestrian, causing $200,000 in damages and medical expenses. The pedestrian sued ABC Plumbing, and without Commercial Auto Insurance, the company would have been liable for the entire amount. However, because they had Commercial Auto Insurance, the policy covered the costs, and the company avoided financial ruin.

What Commercial Auto Costs for Plumbers in Illinois

The cost of Commercial Auto Insurance for plumbers in Illinois varies, but estimated premiums range from $110 to $340 per month. Factors that affect the cost include revenue, payroll, coverage limits, deductible, and claims history. For example, a plumber in Aurora with a clean driving record and low revenue may pay less than a plumber in Chicago with a high revenue and multiple claims. Additionally, the severe winters and flooding risks in Illinois can increase premiums. By maintaining a clean driving record, installing safety devices, and bundling policies, plumbers can lower their Commercial Auto Insurance premiums.

Frequently asked questions

Will my Commercial Auto premium jump after one claim?

Yes, it may. However, the increase will depend on the severity of the claim, your claims history, and other factors. Some insurance providers offer accident forgiveness programs, which can help mitigate the impact of a single claim on your premium.

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

Yes, many insurance providers offer same-day certificates of insurance (COIs) for clients. However, this may depend on the complexity of the request and the provider's processing time. It's best to check with your insurance provider in advance to confirm their COI issuance process and timeline, especially if you have a urgent request from a client in a city like Chicago.

Does a sole proprietor need Commercial Auto?

Yes, if you use your vehicle for business purposes, you need Commercial Auto Insurance, even as a sole proprietor. Personal auto insurance policies typically exclude business use, leaving you unprotected in the event of an accident. Commercial Auto Insurance provides the necessary coverage for your business vehicle, ensuring you're protected against financial losses. As a sole proprietor in Illinois, you can still benefit from Commercial Auto Insurance, especially if you work with clients in cities like Aurora or Naperville.

What's not covered by Commercial Auto?

Commercial Auto Insurance does not cover tools and equipment, which requires a separate policy. Additionally, it may not cover certain types of vehicles, such as motorcycles or RVs, or drivers with poor driving records. For example, you may need to purchase a separate policy to cover your plumbing equipment and tools.

Can I cancel my Commercial Auto policy at any time?

Yes, you can cancel your Commercial Auto policy, but you may face penalties or fees, depending on the terms of your policy. Additionally, consider the potential consequences of canceling your policy, such as leaving your business unprotected against vehicle-related accidents and damages. If you're considering canceling your policy, it's best to discuss your options with your insurance provider to determine the best course of action for your business.

Do I need to list all my vehicles on my Commercial Auto policy?

Yes, you should list all your business vehicles on your Commercial Auto policy to ensure they're covered in the event of an accident. Failing to list a vehicle may result in denied claims or gaps in coverage. This will help ensure you have the necessary coverage for all your business vehicles, regardless of whether you're working in Chicago, Aurora, or other cities in Illinois.

Can I get a discount on my Commercial Auto premium?

Yes, you may be eligible for discounts on your Commercial Auto premium, depending on your business and driving history. Common discounts include those for clean driving records, safety devices, and bundling policies. It's best to discuss your options with your insurance provider to determine which discounts you may qualify for and how you can lower your premium. For example, you may be able to reduce your premium by installing GPS tracking devices or participating in a driver safety program.
