What to Do If You’re Involved in an Accident

If you are involved in an accident in Illinois, here is what you should do to ensure your safety and protect your legal claims:

  • Check for Injuries: Ask yourself, “How do I feel?” “Are others in your vehicle hurt?” If you are hurt or anyone else seems injured, call for emergency help right away.
  • Shift Into Park: If possible, turn your vehicle off, shift it into park, and then turn on your hazard warning lights.
  • Move to Safety: If circumstances allow, safely moving your vehicle out of the flow of traffic can help prevent additional collisions.
  • Call the Police: Report the accident to the police and ask for a copy of the police report. You’ll need it for insurance claims and, if applicable, legal claims.
  • Collect Information From Other Drivers: Be sure to get the names, addresses, and insurance information of other drivers involved in the accident.
  • Take Photos: Take pictures of visible injuries, the accident scene, damage to the vehicles, and damage to property. This evidence is useful to your insurance company and possibly later in a claim.
  • See a Doctor: There might be injuries that you cannot feel at all. Even if you feel perfectly okay, you still need to get evaluated by a medical professional.
  • Contact an Attorney: A skilled car accident attorney can defend your right to pursue compensation and handle communications with other parties. This is especially crucial when dealing with insurance companies.
