For Our Customers

We know that accidents are an inconvenience. You should be comforted knowing that your claim will be handled by a professional adjuster who is experienced in commercial automobile claims. If you insure your vehicle for physical damage with us, we will work with you to get your vehicle back on the road safely and in the shortest possible time. In the event of an accident please follow these instructions:

Make sure no one is seriously injured. Make sure that you, your passengers, and others involved are OK. If anyone is injured, call an ambulance or get other qualified help.

Make sure you're safe. Wherever you are, be sure other vehicles on the roadway can see you. Turn on hazard lights to alert other drivers on the road. If you have safety triangles or cones, use them. Be sure you are safe.

Call the police. Even if no one was hurt, you should call the police if other people, cars, or property are involved in the accident. The police may not come to the scene but it is important that they know about the accident. Also, reporting the accident can help protect you if there are any issues with others involved on the scene or after the fact.

Get information from other drivers. Exchange information with other people involved in the accident. Do not admit fault or liability. Be sure to write down basic contact information for everyone involved, including:

  • Name
  • Address
  • Phone number
  • License plate number
  • Driver's license number
  • Insurance company and policy number

Take photos of the scene and any damage to the vehicles involved to help document the crash. Accidents are stressful. Remain calm and professional. Do not argue with the police or any others involved in the accident.

Contact your insurance company. In the event of an accident, call us to report it as soon as possible. No matter who is at fault or how small the accident appears, it's important to let your insurance company know what happened and have your questions answered. We can work with you and possibly the other drivers' insurance companies to help you get any necessary repairs made as quickly as possible.
