What Should I Do After a Car Accident in Illinois?

If a driver is in a car accident in Illinois, there are steps that should be taken to protect lives and civil rights. After an accident, these are some things individuals should do:

1
Move the Car

The driver should find a safe way to move the car out of traffic and into a secure area. The state allows drivers to move vehicles off the highway to the nearest suitable location that does not obstruct traffic, which could cause more accidents.

2
Stay at the scene

Drivers should stay at the scene of the crash until instructed otherwise by police or other law enforcement. Illinois law states that after an accident, the driver of a car must stay at the scene or face charges.

3
Turn on safety hazards and use traffic control devices

Drivers should turn on their hazard lights. They should also use traffic control devices like safety cones or flares to inform other drivers of the accident ahead. These devices should be placed at a reasonable distance from the crash, ensuring other drivers have ample time to act and respond.

4
Check for injuries

Drivers are encouraged to ensure everyone involved in the crash is checked for injury. Seriously injured individuals should not be moved. Instead, drivers should contact the medical emergency team for assistance.

5
Contact law enforcement

Illinois law states that drivers should report all accidents. However, individuals do not have to call the police immediately after a crash. In addition, when an accident results in injury, death, or property damage worth $1,500 (when all vehicles are insured) or $500 (when any vehicle is uninsured), the driver should report the incident within 10 days.

6
Share information

Drivers must share their name, address, vehicle registration number, and insurance when an accident occurs. Additionally, drivers should provide their driving license if law enforcement or other parties involved request it. If the driver does not own the car, they must provide the owner’s name and address.

7
Take photos for documentation

Drivers are advised to take pictures of the crash. Photos might prove valuable as crucial evidence for legal proceedings and insurance claims. Additionally, investigators can use photos to determine the cause of the accident and the extent of the damage.

8
Notify the insurance company

Drivers should call their insurance company and make a claim within 10 days. The insurer will require information such as the names of those involved, so individuals should have this information at hand.

9
Keep a record

Individuals involved in car collisions in Illinois should always keep records and documentation of the accident. Records like police reports and insurance claims are crucial in case of any legal proceedings.
