Radar Speed Sign

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

Calming traffic. Saving lives. The SPEEDCHECK-15 radar speed sign effectively slows 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 will help to eliminate unnecessary service calls, set a scheduling function that allows for easy programming and unlimited schedules, or measure the compliance results with ease using the precise traffic data and analysis.


  • 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. Cell modem, Ethernet, and other standard traffic communication options are also available.
  • Flashing digits and optional “Slow Down” message can be programmed to flash at user-defined speed thresholds—the faster the speed, the faster the flash. A high-speed cutoff threshold can also be set to prevent drivers from racing the sign.
  • Powered by AC, battery, or solar 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.

SpeedCheck radar signs can be combined with our crosswalk flashing beacons on a single or separate pole, or with an LED enhanced sign for a complete solution. This product comes with a 3-year warranty for peace of mind.

“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:

The SpeedCheck display makes it literally stand out amongst the competition:

  • Unique safety masking on display ensures the display is only visible from the front (up to 3 lanes across), preventing drivers from rubbernecking to read it as they drive past.
  • 7-segment design improves legibility from a distance.
  • Ultra-clear contrast delivers superior viewability in bright sunlight, with no “88” character ghosting.

Read our Manager spec sheet for more information.

SpeedCheck Scheduler

Ideal for school zone applications and anywhere a set schedule is desirable, the SpeedCheck Scheduler is included with SpeedCheck Manager and allows you to program and manage schedules for multiple signs, from simple on/off functions and data collection times to the operation of external devices like flashing beacons and cameras. This easy-to-use scheduler lets you set up to 16 unique events per day over two years. Read our Scheduler spec sheet for more information.

SpeedCheck Traffic Analyzer

When enabled, the radar on SpeedCheck signs can be used to collect the date, time, and speed of over 200,000 vehicles. You can connect to your SpeedCheck display any time and download this collected traffic data. SpeedCheck Traffic Analyzer lets you plot the data, see the success of your traffic calming programs, and identify areas for improvement. Read our Traffic Analyzer spec sheet for more information.
