No, any person in the vehicle at the time can make a claim for any injuries that they have sustained. You do not have to be a driver of a car to make a road traffic accident claim. It can also be made by other road users such as pedestrians, passengers, cyclists and bikers as they are all owed a duty of care by other road users.
A claim can also be made on behalf of a Claimant under the age of 18 by their litigation friend. This is normally their parent who takes over conduct of the claim on the minor’s behalf.
