SpeedCheck Advisory
15- and 18-inch radar-enabled advisory speed signs to alert drivers of an advised speed for a potential road hazard or condition
Highlight sharp curves or other road conditions and improve driver safety on rural roads and exit ramps with intelligent warning displays
Advise drivers if they are traveling too fast when they approach dangerous curves, exits, ramps, pedestrian crossings, or other potential road hazards. The versatile SpeedCheck® Advisory Speed Sign allows for several alert options and can pair with existing static warning signs or flashing beacons.
Available in 15- and 18-inch models, these digital advisory speed signs mount below standard yellow warning signs and use the popular and robust SpeedCheck radar display and system enclosure. Our SpeedCheck products are a proven and effective traffic calming tool to reduce driver speeds in school zones, rural roads, highways, and more.
Features
All 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. Features include:
- 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 battery, solar or AC systems.
Three reasons to choose the SpeedCheck Advisory Sign:
- 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
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 18-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.
SpeedCheck’s unique safety masking

This high-contrast design makes the SpeedCheck sign stand out against the competition. The images below were taken during a side-by-side test and show SpeedCheck’s superior visibility.

SpeedCheck Manager


The SpeedCheck Manager software allows you to easily set up, program, update, and perform maintenance on the SpeedCheck radar speed sign. It can be accessed locally with Bluetooth from up to 50 ft away. Two operating modes as described below:
- Standard operation: All settings for 24/7 operation or as a road speed data collector in stealth mode
- Scheduled operation: Program and manage calendar schedules for multiple SpeedCheck signs, including simple on/off functions, data collection times and operation of external devices like flashing beacons and cameras
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.
SpeedCheck Traffic Analyzer

SpeedCheck radar speed signs have built-in data collection capabilities. Users can connect to their SpeedCheck sign and download traffic data to their laptop via Bluetooth®. Traffic Analyzer software is included with every sign, allowing users to plot the data, see the success of their traffic calming programs and identify areas for improvement.
Product Options and Add-Ons
Advisory Alert Options
We offer three advisory alerts options:
- STATIC SPEED + FLASHING DIGITS: The digital sign can display a static and preset advised speed at all times. With the radar-enabled feature, the display flashes the digits when drivers exceed the advised speed—the higher the speed, the faster it flashes.
- STATIC SPEED + SLOW DOWN MESSAGE: The sign continuously displays the advised speed until a driver exceeds the preset limit. The display then alternates flashing the advised speed with a “slow down” message in 6-inch digits.
- BLANK SPEED ADVISORY + SLOW DOWN MESSAGE: When no advisory speed has been established, a “slow down” alert message can boost the effectiveness of standard warning signs. Drivers approaching at a safe speed see only the static warning sign, but those driving too quickly will trigger the “slow down” message, which flashes at a quicker rate the faster they speed.

We put solar to work™
Whether your project application is a crosswalk, school zone, or 24-hour sign marking, we can run a comprehensive site assessment to confirm the best solar-powered flashing beacon for your project. We run a field-proven software simulation to create a Solar Power Report™ to show you how we did it. Best of all? It’s free, and we can have it ready in 24 hours.
