SPEEDCHECK-12
12-inch digit radar speed sign for school zones, neighborhood streets, and arterial and rural roadways less than 45 mph
Alert speeding drivers with intelligent radar-activated warning SpeedCheck® displays
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. 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.
Features
- 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.
Three reasons to choose the SpeedCheck-12:
- High-contrast display for greatest readability at a distance
- Every sign includes data collection, calendar/schedule operation and reporting software
- 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.
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.
