88 Two - Digit Radar Speed Sign: Elevating Road Safety
The 88 Two - Digit Radar Speed Sign is engineered to significantly enhance driver safety awareness during vehicle operation. It serves a dual - purpose: preventing over - speeding and ensuring that drivers slow down when approaching curves. Additionally, as vehicles enter curves, it alerts oncoming traffic in the opposite lane, promoting safer driving conditions all around.
Working Principle
Leveraging millimeter - wave radar as its detection source, this speed sign functions by emitting electromagnetic waves. Once the radar detects a moving vehicle in its vicinity, it instantaneously transmits a signal to the control board. The control board then undertakes precise calculations and operations, ultimately displaying the current speed of the vehicle.
Should the vehicle's speed be within the set limit, the speed is displayed in green, providing a clear indication of compliance. Conversely, when the vehicle exceeds the set speed, the display switches to red, immediately alerting the driver to the over - speed situation and prompting them to slow down. This intuitive and efficient system plays a crucial role in curbing over - speeding and fostering a safer driving environment.

Besides the standard green for speeds within the limit and red for speeds over the limit, our technical team can change the color settings according to your specific needs. This can be helpful for creating a unique look for your traffic management system or for better visibility in certain lighting situations.
3. What kind of maintenance does the radar speed limit sign need?
The radar speed limit sign is made for low - maintenance operation. Regularly, you should visually check the sign for any signs of physical damage, like cracks in the housing or a dirty display. Wipe the display and housing with a clean, dry cloth to keep them clean. It's a good idea to check the power connections and the radar sensor's function once a year using a simple diagnostic tool from the manufacturer. In most cases, the sign can work for years with little interference.
