When Are you Required To Report A Car Accident?

Wisconsin drivers are required to report motor vehicle accidents that involve:

  • Bodily injury or death;
  • Property damage of at least $1,000 or more; or
  • Damage to a state or government owner property exceeding $200.

Those involved in the accident are required to report the accident to the police department, the sheriff’s department, the traffic department or the Wisconsin State Patrol. If a law enforcement officer responds to the accident, they have 10 days to file a report with the Wisconsin Department of Transportation, or WisDOT.

In some cases, however, law enforcement may not respond to a car accident. In those situations, the individuals involved in the accident are required to report the crash to WisDOT. Drivers may get a letter from WisDOT requesting them to complete a report. If you receive this request from WisDOT, then you are required to complete the report. If you do not file a report or complete a report sent to you by WisDOT, then you may be fined for your failure to comply.

How To Report Your Car Accident

If law enforcement does not respond to your accident, then you will need to submit an accident report to WisDOT. To do this, you will need to complete an online form titled “Wisconsin Driver Report of Crash DT4002.” You can find this form online HERE.

Before you begin filling out the online form, however, you should gather the information that you will need to complete the report. WisDOT will request the following information:

  • Your Driver License Number
  • Your Vehicle Identification Number (VIN)
  • Your Social Security Number
  • Insurance information for the vehicles involved in the accident

WisDOT will also request information about the accident. Specifically, the department will ask you to describe the accident and who was involved. For example, you will need to indicate whether the accident involved a motor vehicle, an animal, a bicyclist, a pedestrian, a parked vehicle or unoccupied vehicle, a fixed object or a non-fixed object.

In addition, you will be asked to discuss any injuries that occurred as a result of the car accident. The report will ask you to indicate whether you have suspected serious injuries (including deep lacerations, broken bones, paralysis, unconsciousness or significant loss of blood), suspected minor injuries (like minor cuts), or possible injuries (such as whiplash, limping or nausea).

Completing the online accident report form should take less than an hour to complete. Not only will reporting the accident help you avoid any potential fines, but you will also be able to use the accident report when seeking damages for your injuries.

Why Is Filing A Car Accident Report Important For My Case?

After an accident, your insurance company will likely request a copy of the accident report. In fact, before an insurance claim can be paid, the driver responsible for causing the accident must be identified. The driver at fault for the accident will then be responsible for compensating the other driver for his or her injuries and property damage.

Often, the accident report will be used to determine who was at fault for a car accident. In the event that there is a dispute regarding who is responsible for causing the accident, the official accident report will serve as the basis for an investigation into how the accident occurred.
