How far should your vehicle's curb side wheels be from the curb?

The correct answer is that your vehicle's curb side wheels should be within 15 centimeters of the curb. This distance allows for safe and practical parking, ensuring that the vehicle is close enough to the curb to prevent obstruction of traffic lanes and is easily accessible for passengers. Keeping within this distance helps maintain the flow of traffic and ensures that the parked vehicle does not protrude into the street, which could pose a hazard to other drivers and pedestrians.

While the other choices present varying distances, parking too far from the curb can create unnecessary hazards and inconvenience, while parking too close could risk damage to the vehicle or impede pedestrian movement. Thus, the 15-centimeter guideline strikes a balance between safety and accessibility.
