What is the minimum spacing requirement between signal warning lamps on school buses?

The minimum spacing requirement between signal warning lamps on school buses is 40 inches. This specification ensures that the warning lamps are adequately spaced to be easily visible to other drivers, allowing for safer conditions when children are getting on or off the bus. Proper visibility of these lamps helps alert motorists to the presence of a stopped school bus and reinforces the necessity for them to slow down and be cautious. This standard contributes to minimizing the risk of accidents in school zones, where children are especially vulnerable. Proper adherence to these spacing requirements is crucial for maintaining safety regulations and enhancing roadway awareness among drivers.
