Final answer:
The speed limit in a school zone when the yellow signals are flashing is generally 15 to 25 mph, though it can vary by location.
Step-by-step explanation:
The speed limit in a school zone when the yellow signals are flashing during indicated time periods is typically 15 to 25 miles per hour, but this can vary based on your location. Motorists should always pay attention to traffic signs and signals for the correct speed limit, especially when flashing lights indicate a reduced speed limit for a school zone. Flashing school zone signals are there to ensure that drivers slow down to help protect the safety of children and pedestrians during times when they are likely to be present, such as when school is starting or ending.
