If your car is parked and your passenger opens the door right into a truck attempting to go around you who is at fault?

This type of claim can go either way. It could be said that the passenger should have looked before opening the door. It could also be said that the driver of the other vehicle did not have the right of way going around on the passenger's side. It is up to the insurance companies to decide. If you are getting resistance from the other driver to claim responsibility, you should make a claim with your insurance carrier and contact a car accident attorney immediately as the insurance carrier may not want to pay for the damages. Fisher & Associates in Colorado is proficient in these kinds of cases.
