Call 911 and wait for the Indiana State Police or the Indianapolis Metropolitan Police Department to respond. You need the police to secure the scene and complete an initial investigation. You should also exchange insurance information with the other driver and get contact information for witnesses. Don't talk about the accident at length, though, and stick to the facts. Don't discuss fault with anyone except your attorney.
Get medical attention as soon as possible. Go to the emergency room at a local hospital like IU Health University Hospital, an urgent care center, or your primary care provider. Even if you feel okay, getting checked out by a doctor is the safest option for your health. And just as importantly, call a verified attorney from this directory to protect your legal rights as soon as possible.
