What signage is typically required on a school bus?

Answer: A — "School Bus" lettering on the front, rear, and sides

The presence of "School Bus" lettering on the front, rear, and sides of a school bus is a crucial safety requirement. This lettering is designed to clearly identify the vehicle as a school bus, enhancing visibility and ensuring that other drivers recognize it as a vehicle that picks up and drops off children. This identification helps promote safer driving behavior in areas where school buses operate, particularly during loading and unloading times when students are present. While signage for low clearance, emergency contact numbers, and "Do Not Disturb" signs may serve specific purposes in different contexts, they do not fulfill the primary need for clear identification of the vehicle as a school bus. Most importantly, the unmistakable "School Bus" lettering is essential in alerting motorists about the potential presence of children, thereby helping to reduce the risk of accidents.
