How many and what color warning lamps should a school bus have?

A school bus is required to have a specific configuration of warning lamps to ensure the safety of students when boarding or disembarking from the bus. The correct configuration for a school bus includes two front and two rear red warning lamps that flash alternately. This red color is crucial because it signals to other drivers that the bus is making a stop, and they must be prepared to either halt their vehicle or slow down significantly as children may be crossing the street.

The flashing red lights alert drivers to the important safety measure of ensuring children are boarding or exiting the bus safely. This is part of the laws governing school buses to prevent accidents and protect young pedestrians. The other options either mention incorrect color combinations or do not meet the legal requirements regarding the number and types of lamps.
