How far must the right-hand wheels of a vehicle be from the curb when parked on a two-way roadway?

When parking on a two-way roadway, there are specific regulations regarding the distance that a vehicle's right-hand wheels must be from the curb to ensure safety and accessibility. The requirement states that vehicles must be parked with the right-hand wheels no more than 18 inches away from the curb. This distance helps maintain smooth traffic flow, allows ample space for pedestrians to walk along the sidewalk, and ensures that vehicles are safely positioned without obstructing the roadway.

Choosing 18 inches as the distance aligns with general guidelines provided in transportation regulations. It strikes a balance between not being too far from the curb, which could create hazards, and not being too close, which might risk damage to the vehicle or hinder pedestrian movement. The other distances listed may not correspond with official parking regulations, thus making them less appropriate choices.
