Radar Speed Sign
Intelligent radar speed signs alert speeding drivers on highways
Effective. Versatile. Durable. The SPEEDCHECK-18 radar speed sign is a traffic calming tool for highway and expressway applications with posted speeds over 45 mph. Also known as driver feedback signs, these traffic calming devices are proven to show measurable results. The speed detection display sign flashes 18-inch, bright LED digits, making it easy for drivers to understand at a glance if they are exceeding the posted speed limits, and react by slowing down.
This radar speed sign includes two-way wireless communication, either onsite or remotely, for setup, diagnostics, upgrades, and more. Optional features will help to eliminate unnecessary service calls and set a scheduling function that allows for easy programming and unlimited schedules. Measure the compliance results with ease using the precise traffic data and reporting that is available for analysis.
- On-site Bluetooth® wireless connectivity is available on all SPEEDCHECK-18 models—without cellular service fees. 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.
The SpeedCheck-18 is listed in the Federal Highway Administration’s (FHWA) Manual on Uniform Traffic Control Devices (MUTCD), meaning it is approved for use in the United States. 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.
STUDIES SHOW: According to a 2008 report from the Transportation Research Board, radar speed signs had a mean speed reduction of 1.7 mph in high-speed locations.
Top 3 reasons the SPEEDCHECK-18 display is better than the competition:
- Unique safety masking ensures the numbers are 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.

"YOUR SPEED" Sign Size and ColorsThe SpeedCheck-18's static sign comes in a variety of colors for a variety of applications. The standard sign sizes is 48"x36". There are also four sign colors available based on MUTCD guidelines. If you'd like to learn more about MUTCD guidelines for radar speed signs, read our quick guide here.
White (not MUTCD standard)
Yellow (used for most applications)
Fluorescent yellow-green (used for school zones)
Orange (used for work zones)
SpeedCheck SchedulerIdeal for school zone applications, the SpeedCheck Scheduler is included with the SpeedCheck Manager software that allows you to program and manage schedules of multiple SpeedCheck radar 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 AnalyzerSpeedCheck radar signs automatically 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. The SpeedCheck Traffic Analyzer add-on lets you plot the data, see the success of your traffic calming programs, and identify areas for improvement.
