SpeedAlert Radar Message Signs

SpeedAlert Radar Message Signs

Portable multipurpose radar message signs combine messages with radar feedback.
Web-enabled for data collection and remote management.

SpeedAlert radar message signs combine radar feedback and messaging, so you’ll use it more often in more situations.


  • Multipurpose: Give drivers immediate feedback by displaying messages specific to their speed (“Slow Down”, “Too Fast!”, “Have a Nice Day”); or display dedicated messages (“Flood Warning”, “Amber Alert”) depending on your needs at the time.
  • Simple, Universal Mounting: Mount the SpeedAlert radar message sign on a portable post, pole, ultra-portable trailer or vehicle hitch in just minutes.
  • Durable Construction: The welded aluminum enclosure, concealed mounting hardware, shatterproof Lexan and graffiti-resistant powder-coat make the SpeedAlert radar message sign extremely rugged and durable. Weatherproof, too!
  • Flexible Power Options: Accommodates almost any power source including Lithium battery, Integrated Solar, AC or trailer. A dedicated compartment allows simple battery exchange in any weather.
  • Remote Management: Remotely access and monitor the SpeedAlert radar message sign  from anywhere with an Internet connection and browser using the ATS TraffiCloud Remote Management Service.
  • Eliminate Data File Management: Upload data automatically, generate and share ready-made reports from computer or tablet. Easy-to-use interface with dashboard convenience.  Requires TraffiCloud subscription
  • Alerts: Set email or text alerts for high-speed violators, low batteries and tampering.  Requires TraffiCloud subscription
  • Other features include: Display speed data or speed-dependent messages, ability to program to different modes, easy-to-manage onboard buttons, collect volume and speed data even when sign is in message mode, local setting changes, flashing red and blue violator strobe, and ability to take daytime awareness images.

Watch this SpeedAlert 24
speed trailer in action:

The SpeedAlert 18” trailers were instrumental in monitoring and slowing approaching vehicles to allow for safe pedestrian crossing.  Compared to a 4-week analysis taken in November 2021, a 106% increase in traffic flow was documented by the SpeedAlert 18” trailers in May 2022. The All Traffic Solutions equipment was key in ensuring the safe and efficient flow of over 99,000 vehicles during these events.

The [SpeedAlert] is so versatile and the quality is second to none.

– Chris Hatton, Chief of Police, Sylva Police Department

The energy-efficient signs display real-time vehicle speeds and flash a “slow down” message with red and blue lights to speeding drivers while law abiding drivers get a “Thank you” Message! These signs made such a positive impact on our community.
