How far must a vehicle park from the curb when parallel parking on a two-way highway?

Answer: B — Within 12 inches

When parallel parking on a two-way highway, the correct distance a vehicle must park from the curb is within 12 inches. This guideline is in place to ensure that vehicles remain close enough to the curb to avoid obstructing traffic while also allowing enough space for vehicles to maneuver safely in the roadway. Parking too far away from the curb can create hazards for other drivers and can lead to potential collisions, as drivers may need to swerve around the parked car. The 12-inch limit helps maintain a balance between safety and accessibility, making it easier for pedestrians to navigate the sidewalk as well. This regulation is part of ensuring overall traffic flow and safety on public roads.
