What is the minimum clear space required between a parked vehicle and the roadway?

The correct answer is that the minimum clear space required between a parked vehicle and the roadway is 0.5 meters. This regulation is designed to ensure that parked vehicles do not obstruct the flow of traffic or create hazards for other road users. A 0.5-meter clearance allows sufficient space for pedestrians to pass safely by the vehicle, as well as providing room for emergency vehicles to navigate if necessary.

Maintaining this distance is crucial for maintaining safety on the roadway. Vehicles parked too close to the street can pose risks such as obstructing visibility for drivers, leading to potential accidents. Therefore, such guidelines are set to promote safety for everyone on the road.

The other options suggest larger clearances, which, while they may appear to enhance safety, are beyond the minimum requirement. Establishing a minimum that balances safety and practicality is essential for overall traffic management, and 0.5 meters serves that purpose effectively.
