What is one risk of riding too close to parked cars?

Answer: B — Increased risk of being hit by an opening car door

Riding too close to parked cars significantly increases the risk of encountering an unexpected opening car door, often referred to as "dooring." Drivers and passengers may exit their vehicles without checking for approaching motorcycles or other traffic, leading to sudden and dangerous situations for riders. When a door swings open into the lane, a motorcycle rider may not have enough time or space to avoid a collision, which can result in serious injuries or loss of control over the motorcycle. This is particularly relevant in urban environments, where parked cars line the street and can create hazards for those riding nearby. The other options do not capture the specific hazards associated with being near parked vehicles. For instance, the chance of hitting pedestrians focuses on interaction with people rather than vehicles, and enhanced visibility or reduced need for lane changes do not address the immediate dangers of dooring.
