If you are physically able, call the police as soon as possible so they come to the scene of the accident. Law enforcement will arrive, gather information and do a preliminary investigation of the accident. While you are waiting, use your time to exchange contact and insurance information, and also get contact information from any eyewitnesses. It’s also in your best interest to use your cell phone to take pictures of damage and any visible injuries. In severe accidents, emergency response teams typically arrive, and you might be transported to the nearest hospital via ambulance. If you refused medical treatment at the scene, you need to get checked out by a doctor as soon as possible.
Keep in mind that alcohol affects people differently; some become angry and belligerent. You may not immediately notice whether the other driver has been drinking, so you should always proceed with caution. If you are able to move from your vehicle, you should make sure emergency services are on their way if the other driver is trapped in his car. Yet, unless the driver specifically addresses you, don’t strike up a conversation. Wait until law enforcement arrives. If the driver is angry and screaming at you, stay in your car, if it is safe, until others arrive.
