When parallel parking your vehicle, you should park within this distance from the curb:

Answer: A — 6-12 inches

When parallel parking your vehicle, it is important to park within 6-12 inches from the curb. This distance allows for enough space for other vehicles to pass and maintains a safe distance from the flow of traffic. Parking too far from the curb can obstruct traffic and make it difficult for other drivers to navigate around your vehicle. Similarly, parking too close to the curb can make it challenging to safely enter and exit your vehicle. Therefore, parking within 6-12 inches from the curb is the most appropriate and safe distance for parallel parking.
