What Commercial Auto Covers for Plumbers in South Dakota

Commercial Auto Insurance pays for liability, collision, and physical damage to company cars, vans, and trucks. For example, if a plumber's vehicle is involved in an accident while driving to a job site in Rapid City, Commercial Auto Insurance would cover the damages. However, it does not cover tools and equipment, which is typically covered under a separate policy, such as Tools & Equipment Insurance. Another example is if a plumber's vehicle is damaged in a hailstorm in Aberdeen, Commercial Auto Insurance would cover the repairs.

Do Plumbers in South Dakota Need Commercial Auto?

While Commercial Auto Insurance is not legally required for plumbers in South Dakota, it is often contractually required by clients, landlords, or contractors. Most general contractors, commercial property managers, and municipal clients require plumbers to carry at least $1 million in general liability coverage before they are allowed on a job site. Additionally, many clients require the plumber to be listed as an additional insured on the certificate. Without Commercial Auto Insurance, plumbers in South Dakota risk being unable to work on certain job sites or facing financial losses in case of an accident.

However, plumbers can lower their premium by maintaining a good driving record, installing safety devices in their vehicles, and choosing a higher deductible.

Frequently asked questions

Will my Commercial Auto premium jump after one claim?

Yes. Commercial Auto premiums may increase after a claim, depending on the severity of the accident and the insurance provider. However, some insurance providers offer accident forgiveness or other discounts that can help mitigate the increase in premium. For example, a plumber in South Dakota who has a clean driving record and has been with the same insurance provider for several years may be eligible for accident forgiveness, which can help keep their premium lower after a claim.

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

Yes. Many insurance providers offer same-day certificates of insurance (COI) for clients. Plumbers in South Dakota can request a COI from their insurance provider and receive it on the same day, allowing them to start work on a job site immediately. However, some insurance providers may require additional documentation or information before issuing a COI, so it's best to check with the provider in advance.

Does a sole proprietor need Commercial Auto?

Yes. Sole proprietors in South Dakota who use their personal vehicle for business purposes may still need Commercial Auto Insurance. If the vehicle is used for both personal and business purposes, a personal auto insurance policy may not provide adequate coverage in case of an accident. Commercial Auto Insurance can provide additional protection and help sole proprietors avoid financial losses in case of an accident.

What's not covered by Commercial Auto?

Commercial Auto Insurance does not cover tools and equipment, which is typically covered under a separate policy, such as Tools & Equipment Insurance.

Can I cancel my Commercial Auto policy at any time?

Yes. Plumbers in South Dakota can cancel their Commercial Auto policy at any time, but they may be subject to a penalty or fee. It's best to review the policy and understand the cancellation terms before signing up. Additionally, plumbers should consider the potential risks of canceling their policy, such as being unable to work on certain job sites or facing financial losses in case of an accident.

How do I get a quote for Commercial Auto?

To get a quote for Commercial Auto Insurance, plumbers in South Dakota can contact an insurance provider or broker and provide their business information, including revenue, payroll, and contract limit requirements.
