When a person is injured in a bicycle accident, the law in Florida is very specific when it comes to responsibility in a car-bike collision. The careless driver of a motor vehicle is legally responsible for any damages, physical, emotional, and economic, caused to the bike rider. In Florida, drivers of cars and trucks have a duty to observe their surroundings at all times. When they fail to do so, and strike a bike rider, they will be liable for any losses, both personal and economic, suffered by that rider.
