Delaware Defensive Driving Practice Test

What might indicate that a cyclist is riding really close to parked cars?

1. The width of an open vehicle door

2. The speed of the vehicle passing

3. The type of bike they ride

4. The traffic light colors

The correct answer is: The width of an open vehicle door

When observing a cyclist riding near parked cars, one significant indicator is the width of an open vehicle door. This is an important consideration known as the "door zone." Cyclists often position themselves to avoid the potential hazard of a suddenly opened door, which can occur when an occupant exits a parked car. If the space between the parked cars is narrow or if a door is opened into that area, the cyclist may be riding closer to the cars to navigate safely around that risk. This awareness helps cyclists maintain a safe distance from parked vehicles while also anticipating the potential for dooring incidents. Understanding this aspect reinforces the importance of being cautious and aware of both cyclists' positioning on the road and the risks associated with parked cars. This knowledge is beneficial for both cyclists and drivers to promote road safety for all users.
