When must a driver stop when approaching a stopped school bus unloading children on a two-lane road?

A driver must always stop when approaching a stopped school bus that is unloading children on a two-lane road. This law is in place to ensure the safety of children who are getting on or off the bus, as they may suddenly enter the roadway without warning. The requirement to stop is applicable regardless of the direction the vehicle is traveling, the presence of children crossing the street, or whether the bus's lights are flashing. This comprehensive stopping requirement is designed to minimize the risk of accidents and to safeguard the lives of children in the vicinity of school buses. In South Carolina, adhering to this law is crucial, as it reflects a commitment to protecting the most vulnerable road users.
