A driver is at-fault and must pay for the damages he or she caused whether you were hit in a car, riding a bike or walking. When it concerns compensation for injuries, the law does not differentiate between drivers, bike riders and pedestrians.
If you were injured by an at-fault driver (regardless of your mode of transportation at the time you were struck), the law entitles you to what is commonly referred to as compensatory damages. This includes property damage (i.e. your bike) as well as bodily injury. Bodily injury damages include the full expense of all medical costs, lost wages incurred from the wrongful act, loss of earning capacity, pain and suffering- physical, mental and emotional, damage to credit, etc.
In other words, the law is designed to compensate victims in a manner that places them in the place they were prior to being injured. If a person that is hurt had a pre-existing physical or mental condition that was aggravated or otherwise made worse by an accident or wrongful act, that too is compensable.
How are your damages paid if you were riding a bike or walking? The at-fault driver’s insurance liability policy will pay for the damages.
If the driver is not insured (uninsured) or there is not enough money in the at-fault’s policy to pay for the full extent of the damages (i.e. the driver is underinsured), then your own automobile policy may compensate you for the full amount of the damages, despite the fact that you were not in a car when you were injured.
This is because uninsured and underinsured motorist coverage (if you do not waive it when you purchase your automobile insurance policy) is “portable,” i.e. it follows the person, not the car. Consequently, as long as you were struck by a vehicle your uninsured or underinsured motorist coverage applies, regardless of whether you were in a vehicle when you were injured.
