Here's a pair of school zones flashers that are used here, these are usually mounted near elementary schools that are on a busy road to warn drivers of a school zone ahead and of the reduced speed limit that is in effect.
Hmm haven't seen a solar powered school zone flasher before, this one is a older sign since it reads MAX. SPEED and the newer ones read MAXIMUM on the top.
If you look really closely you can see that there is a older sign under the yellow school zone sign .
