It is common to wonder if your auto insurance will cover your injuries and property damages in a bike accident. You could have serious injuries and your bike could be destroyed, so this is not a minor issue. While every insurance policy is somewhat different, it is likely your policy will cover a bicycle accident if the following are true:
The accident should involve a motor vehicle of some kind. It actually does not matter most of the time if you were on a bike, in a car, ATV or something else. At least one of the vehicles involved needs to be a motor vehicle. In that case, your auto insurance should cover your damages.
The accident was the fault of the driver. If the accident was your fault, it is likely your auto insurance provider will deny the claim. If you are 50% at fault for the accident, it is likely the auto insurance policy would cover 50% of your damages. So if you have $1000 in injuries and property damage and were 50% responsible, you could receive $500 from the insurance company.
