What color is the curb if you can only stop long enough to pick up or drop off passengers?

The correct color of the curb that indicates you can only stop long enough to pick up or drop off passengers is white. In many jurisdictions, including Virginia, a white curb designates an area where stopping is limited to short periods for loading or unloading passengers. This allows drivers to assist passengers safely without leaving their vehicle for extended times, ensuring a steady flow of traffic.

The other colors have specific meanings: red often indicates no stopping, standing, or parking at any time, which is meant to ensure safety in high-traffic areas. Yellow typically signifies a loading zone, where commercial vehicles can stop to load or unload goods but might not be appropriate for general passenger loading. Blue curbs are generally designated for disabled parking, allowing those with proper permits exclusive access to these areas. Understanding these curb color codes is essential to comply with parking regulations and ensure safety on the roads.
