What should cyclists be cautious of when riding near parked cars?

When riding near parked cars, it is crucial for cyclists to be cautious of potentially opening doors. This is often referred to as the "dooring" hazard. When a driver or passenger is inside a car and decides to exit, they may open the door without checking for oncoming cyclists. If a cyclist is riding too close to the parked vehicle, they may collide with the door, which can lead to serious injury.

The risk is heightened in urban areas where parked cars are common, and cyclists need to maintain a safe distance when passing by to avoid this danger. By being alert and watching for signs that someone might be about to open a door, cyclists can better safeguard themselves against accidents caused by dooring.
