30 Days of Traffic Signs - Day 3
Regulatory Signs
Regulatory signs tell drivers what they must do. Most people think of stop signs, speed limit signs, and no turn signs, but regulatory signs can also be electronic or temporary. If the sign is posted and active, drivers are expected to follow it.
One mistake I see is drivers treating temporary construction signs or electronic signs like suggestions. Just because a sign wasn’t there yesterday doesn’t mean you can ignore it today. If it’s a regulatory sign, it’s creating a rule for drivers.
What’s a regulatory sign you see people ignoring all the time?
