Every school should have school crossing signs. These signs consist of messages that warn drivers of pedestrians using crosswalks near the campus.

Good sign visibility helps attract new patrons to establishments. It's also one of the most important factors that helps reduce traffic accidents.

There are multiple reasons to post MUTCD signs in specific locations, but each sign must ultimately fulfill a need, get attention, and deliver a simple message.

​Construction zones near roadways need plenty of orange or yellow signs to remind drivers to slow down for worker safety.
