Flashing LED W3-5 Reduced Speed Limit Ahead Sign
Trying to improve safety on your roadways but not sure where to start? You’re in the right place! Here at Dornbos Sign & Safety, Inc. we offer a variety of traffic control signage to fit your every need. According to the MUTCD, Reduced Speed Limit Ahead signs should be placed where speeds reduce by 10 mph or more or when engineering judgment indicates the need for advance notice (source). Featuring eight High Intensity synchronized LED lights, this sign extends the range of visibility over standard traffic control signs. Use this LED lighted sign to increase driver awareness of changes in speed limit.

Flashing LED Illuminated Reduced Speed Ahead signs are MUTCD compliant and available in a range of sizes and flashing options to ensure that each sign meets the specific needs for your intersection. Standard size for roadways is typically 36” x 36” but requirements for size vary from state to state—it is the responsibility of the purchaser to ensure signs meet local specifications.
