What is the reference point for stopping 6 inches from a curb?

The reference point for stopping 6 inches from a curb is positioned over the right headlight. This point helps drivers gauge their distance from the curb while parallel parking or performing similar maneuvers on the right side of the road. By using the right headlight as a reference, drivers can maintain the correct spacing and avoid hitting the curb, which can cause damage to the vehicle or create an unsafe driving situation. This practice encourages safer driving habits, especially in urban areas where curbs are common.

Using different reference points, such as the left headlight or anything in the rear view mirror, would not provide the optimal guidance for determining the appropriate distance to the curb. Each reference point serves its purpose depending on the context of the vehicle's position and movement, but when it comes to stopping near a curb, the right headlight reliably indicates the desired distance.
