In a bicycle accident, determining who is responsible for your medical bills and other expenses will depend on the specific circumstances of the accident. If the accident was caused by the negligence of another driver, then their insurance company may be responsible for paying your medical treatment and other expenses. If the accident was caused by a defective product or poor road conditions, then the responsible party may be a manufacturer, government entity, or other party. An experienced bicycle accident lawyer can help you determine who is responsible and pursue compensation on your behalf.
