If you were a passenger in an auto accident in Georgia, you have the same rights as drivers do when it comes to seeking compensation for your injuries and losses. You can bring a claim or lawsuit against any negligent party, regardless of whether you were in the car with the at-fault driver or if the at-fault driver was someone else. If multiple parties are responsible for your injuries, then you can file multiple claims. All responsible parties will split liability.
There are situations where the passenger will have contributed to the accident through negligence of their own, such as being distracting or grabbing the wheel. If you were negligent in the accident as well, then this will impact your claim.
