Under what condition can you stop at a yellow curb?

A yellow curb indicates a designated area where stopping is restricted to specific activities. The primary purpose of yellow curb markings is to facilitate loading and unloading of passengers or freight. Stopping in these areas is allowed only when actively engaged in loading or unloading, which helps ensure that the flow of traffic is not impeded and that safety is maintained.

Parking for a short time or waiting for passengers would typically violate the regulation associated with yellow curbs, as these actions could contribute to congestion and hinder the movement of other vehicles. The prohibition against stopping altogether on yellow curbs ensures that they remain clear for their intended purpose of facilitating loading and unloading activities.
