What is a common danger for cyclists when riding near parked vehicles?

When cyclists ride near parked vehicles, one significant danger is the risk of drivers opening doors without checking for approaching cyclists. This situation is commonly referred to as "dooring." It presents a serious hazard because if a door swings open unexpectedly, a cyclist may not have enough time to react and could collide with the door, leading to potential injury or loss of control. Cyclists need to maintain a safe distance from parked vehicles to mitigate this risk.

Flat tires can occur but are not specifically linked to the danger posed by parked vehicles. While pedestrian interactions can happen, they are not as prevalent a concern as the sudden opening of vehicle doors in urban settings. Excessive noise from engines does not pose a direct danger to cyclists and is more of an environmental issue than a specific cycling hazard. Thus, the risk of dooring remains the primary concern for cyclists navigating areas with parked cars.
