Final answer:
Legally, you must stop and not pass a school bus with flashing lights and extended stop arm. If the bus is stopped without these signals, follow the posted speed limit with caution. Always prioritize safety in school zones.
Step-by-step explanation:
The speed at which you can legally pass a school bus that is stopped at a school's entrance is dependent on traffic laws that can vary by jurisdiction. In most cases, when a school bus is stopped with its lights flashing and stop arm extended, it is illegal to pass the bus at any speed in either direction on an undivided road. However, the specifics can be different based on local traffic laws, and you are typically expected to stop, not pass the bus.
If a school bus is simply stopped at a school’s entrance without flashing lights or an extended stop arm, typical traffic rules apply. You should follow the posted speed limit and exercise caution, being mindful of the possibility of children entering or exiting the bus. You’re reminded to always prioritize safety over haste, especially in school zones.
