What should drivers be aware of when they see red or yellow painted curbs?

When drivers encounter red or yellow painted curbs, they need to be mindful that these colors typically indicate restrictions on parking. Red curbs usually signify that parking is absolutely prohibited in that area, often implemented for fire lanes or to ensure that emergency vehicles can access certain locations unimpeded. Yellow curbs generally indicate that parking is allowed for brief periods, often designated for loading and unloading or to facilitate pick-up and drop-off activities.

Understanding these color codings helps maintain safety and access, particularly in urban settings where space can be limited. This awareness is crucial for compliance with local regulations and to avoid receiving parking violations. The other options do not accurately represent the meaning of these colored curbs, as they relate to aspects like parking rules rather than speed limits or construction zones.
