What is an exception to the school bus stop law?

Answer: B — When traveling the opposite direction on a multi-lane highway

When traveling the opposite direction on a multi-lane highway, vehicles are not required to stop for a stopped school bus that is unloading or loading passengers if there are at least four lanes of traffic separating them. This exception exists because the design of multi-lane highways typically affords enough space and visibility that it is safe to continue driving without stopping for the bus, as long as the lanes are clearly divided and separated by a physical barrier, such as a median. This consideration prioritizes safety while also allowing for the efficient flow of traffic on larger roadways. It's important for drivers to remain vigilant and aware, as they still need to keep an eye out for children who may unexpectedly cross the road.
