If a school zone sign reads “7 a.m. to 5 p.m. School days,” does that mean Monday through Friday? What if it is a weekday, but I know that there is no school that day?

Samuel, if the sign reads “Speed Limit 20, School Days 7 a.m. to 5 p.m.” and it is not a “school day” for whatever reason, you’re off the hook and can proceed at the nonrestricted, posted speed limit, according to Medford police.

Weekdays during summer, winter and spring beaks are not technically “school days,” said Medford police Lt. Kerry Curtis.

However, if the sign reads “Speed Limit 20 when children are present,” then you need to slow down any time — day or night — there are children walking in a crosswalk or waiting on the curb or shoulder of a highway at a crosswalk, Curtis said.

And, obviously, if the sign reads “Speed Limit 20 when flashing,” then reduce your speed to 20 mph if the light is flashing.
