What is required of a driver when a school bus has its stop sign extended in Iowa?

When a school bus has its stop sign extended, a driver in Iowa is required to stop and wait until the stop sign is withdrawn. This law is in place to ensure the safety of children getting on or off the bus. The extended stop sign indicates that children may be crossing the street, and stopping allows them to do so safely without the risk of being hit by an oncoming vehicle.

Continuing to drive at the same speed or passing the bus at a reduced speed would put children at risk and violate Iowa law. Honking the horn does not contribute to safety in this situation; it could potentially distract or startle children. Thus, the safest and most responsible action is to stop and remain stationary until the bus signals that it is safe to proceed. This practice is a critical component of ensuring the safety of young passengers and follows the regulations set to protect children in these scenarios.
