Radar Speed Sign

Alert speeding drivers with intelligent radar-activated warning SpeedCheck® displays

Affordable. Reliable. Feature-rich. The SPEEDCHECK-12 radar speed sign is an effective and portable solution for slowing traffic in pedestrian and school zones, residential areas, and arterials and rural roadways with posted speeds less than 45 mph. Also known as driver feedback signs, these traffic calming devices effectively draw the attention of drivers who are exceeding posted speed limits, allowing those targeted drivers to self-correct.

SpeedCheck systems have the added benefit of delivering two-way wireless communication, either onsite or remotely, for setup, diagnostics, upgrades, and more. Optional features include remote monitoring for programming, updating, and status monitoring from afar, additional static sign sizes and colors, extended radar range and others.


  • Mobile app for iOS® and Android™ enables quick and easy setup and programming from up to 50 ft away using on-site Bluetooth® wireless connectivity.
  • Built-in rapid-flashing strobe can be programmed to flash at user-defined speed thresholds.
  • Powered by battery, solar or AC systems.

Carmanah SpeedCheck signs meet the guidance of the Federal Highway Administration’s (FHWA) Manual on Uniform Traffic Control Devices (MUTCD). Many states have SpeedCheck devices on their approved product list. It is also approved by the Transportation Association of Canada (TAC) and other safety bodies around the world.

“We have installed SpeedCheck displays in several new locations throughout the city as well as replaced some of the less reliable signs we had previously purchased from a different manufacturer. SpeedCheck displays have proven to be easy to install, rugged, and reliable.”
– Doran Beauclair, Signal Electrician, City of Bellevue, Washington

Top 3 reasons to choose our SpeedCheck radar speed sign:

  1. High-contrast display for greatest readability at a distance
  2. Every sign includes data collection, calendar/schedule operation and reporting software
  3. Customizable options for static signs, power sources, remote connectivity and more

High-contrast Display

We achieve a high-contrast, ultra-clear display with high-intensity LEDs and our unique safety masking design. The bright LED display uses 12-inch, MUTCD-compliant digits against a black background that prevents “88” ghosting—ensuring readability in all weather and lighting conditions. The protective, polycarbonate window is anti-glare and UV-stabilized for high clarity, and features a unique safety mask that limits the viewing angle to prevent drivers from watching the display as they pass.
