What should be your primary concern when approaching a parked car?

When approaching a parked car, the primary concern should be that the vehicle may pull out or turn across your path unexpectedly. Parked cars often have drivers who may not be fully aware of their surroundings, and if they decide to maneuver their vehicle, they can pose a significant risk to motorcycle riders. This scenario is particularly hazardous because it could happen quickly and without warning, especially if the driver is not using their mirrors effectively or is distracted.

While other concerns like whether the car's engine is running or if the driver is looking in your direction are important, they do not directly indicate the immediate danger posed by the vehicle moving into traffic. The potential for a U-turn or an abrupt pullout is a proactive threat that requires a motorcyclist to stay alert and be prepared to react. Therefore, focusing on the possibility of a parked car engaging in sudden movement is crucial for ensuring safety while riding.
