✅ D. 6 to 18 inches from the curb
When parking parallel, most traffic laws require that the curbside wheels be within 6 to 18 inches from the curb. This ensures that the vehicle is safely positioned without obstructing traffic or posing a hazard to pedestrians.
Proper parallel parking ensures safety, compliance with regulations, and smooth traffic flow. Always check local laws, as requirements may vary slightly by region.
