Your first call immediately after your collision should be 911. Then, stay at the scene. Either a police officer from the Portland Police Bureau or a state trooper from the Oregon State Police will respond to your collision. If you can safely do so, start gathering evidence at your crash site. Take photos of your accident. Get contact information from witnesses. As soon as possible, see a doctor as well. Get medical attention at Providence Portland Medical Center, OHSU Hospital or another nearby hospital. Finally, call a lawyer right away. That way, you will better understand your legal rights.
