First thing you have to do is call the police, especially if anyone is injured in the accident. The police report is the most important way to document what happened. It will help your insurance company and your lawyer figure out who is responsible for damages.
If a police officer on the scene gives you a ticket, it still doesn't necessarily mean you're responsible for the accident. Don't just send in the fine or plead guilt. That could damage your chance of compensation for damages later. Make sure you consult an attorney who is familiar with auto accident law in Wisconsin, and also your insurance agent before you plead or send in any fines.
Don't admit fault to the police, the other drivers, or anyone. The facts may not be as simple as they may seem. It is always best to use discretion. Tell the truth about facts you know but don't speculate as to what may have happened.
Get the other driver's name, address, telephone number, their license number, their insurance company and policy number. Make sure you find out who owns the other vehicle, the license plate number, the make and model of their car. Collect names, addresses and phone numbers of witnesses and passengers. You should also make notes about the weather and street conditions, road conditions, traffic signals, skid marks and positions of the vehicles before and after the accident.
Let your insurance agent know as soon as possible, as otherwise you might risk being denied coverage.
See a doctor if you think you were injured in the accident. A doctor may notice symptoms you wouldn't. Never settle with the insurance company until the full extent of your injuries are determined. This can take months; so don't be pressured into an early settlement.
If the relevant insurance companies don't settle in cases involving auto accident law in Wisconsin, a jury will be asked to resolve the dispute. Well over 90 percent of auto accident negligence cases in Wisconsin are settled without going to trial, however. Chances are very good that you will be able to settle your case without going before a jury.
