About School Bus Yellow Color

National School Bus Glossy Yellow is a vehicle-identification color rather than a casual name for any warm yellow. NHTSA’s pupil-transportation guidance recommends a uniform yellow body with contrasting black identification so motorists can recognize a school bus quickly, especially when children are loading or unloading.

The legal nuance is important: NHTSA explains that federal vehicle safety standards do not themselves require every school bus to be yellow; state and local policy governs operation and identification, informed by federal program guidance. The published recommendation points to a physical federal color standard. A website HEX may evoke the convention but cannot establish compliance for a vehicle, coating, sign, or jurisdiction.

This digital swatch is not a vehicle paint approval, legal opinion, NIST match, state compliance determination, or substitute for current transport regulations.
