What must you do if you approach a school bus with its stop sign extended?

When you approach a school bus that has its stop sign extended, you must stop your vehicle regardless of your direction of approach. This regulation is in place to ensure the safety of children boarding or exiting the bus. The extended stop sign signals that children may be present in the vicinity, and stopping allows them to cross the road safely without the risk of being hit by a vehicle.

Stopping for a school bus is a critical traffic law, and it is not just applicable to vehicles traveling behind the bus. Vehicles approaching from either direction must adhere to this rule, reinforcing the importance of vigilance when in school zones or areas where children are likely to be present. This safety measure helps to protect some of the most vulnerable road users—children—by ensuring that they can load and unload from the bus without danger.
