What color is the curb if you can't stop, stand, or park?

The color of the curb indicating that you cannot stop, stand, or park is red. This color is universally recognized as a no-parking zone. It is used to signal that any type of vehicle activity, including stopping for temporary purposes, is prohibited in that area. Red curbs are often found in locations where safety and traffic flow need to be prioritized, such as near fire hydrants, intersections, or other critical areas where parked vehicles could obstruct visibility and movement.

Yellow curbs typically indicate that loading and unloading of passengers or freight is allowed, but parking for extended periods is not permitted. White curbs are designated for passenger loading and unloading only, allowing short stops. Blue curbs are reserved for accessible parking for individuals with disabilities. Understanding these color codes is crucial for safe and lawful driving behavior.
