The first thing you need to do after a Phoenix motorcycle accident is to get out of the danger zone. Do not talk to anyone at the accident scene except the responding police officer. Just saying sorry can be used against you later as an admittance of fault.
Make sure you take as many pictures as possible. You should also get the contact information of witnesses present at the accident scene. Don’t refuse medical treatment even if you don’t feel pain or have any visible injuries. You could have internal damage. Unless you have legal representation, do not sign any documents or accept a settlement from the driver’s insurer.
