A school zone speed limit sign has yellow lights that a time clock controls. When must you obey the lower school speed limit on this sign?
Correct answer: Only while its lights flash and children are present
Why
A town or county may set a school speed limit of 15 mph or more. It applies only when the signs are posted, the warning lights flash and children are present. When the lights are dark, obey the normal posted limit, but stay alert, because children may still be near a school.
