The 88 Two - Digit Radar Speed Sign is designed to enhance driver safety awareness by preventing over-speeding and promoting slower speeds near curves. It also notifies oncoming traffic to improve overall driving conditions.
Working Principle:
Utilizing millimeter-wave radar, this speed sign emits electromagnetic waves to detect moving vehicles. When a vehicle is detected, a signal is sent to the control board for speed calculation and display.
If the vehicle is within the speed limit, the display shows green for compliance. However, if the vehicle exceeds the speed limit, the display turns red to alert the driver to slow down. This system effectively helps prevent over-speeding and ensures a safer driving environment.

1. Are radar speed limit signs the same as speed cameras?
No. Radar speed limit signs mainly display the vehicle's speed to remind drivers to control their speed. Speed cameras, on the other hand, are used to capture images of vehicles that exceed the speed limit for law enforcement and ticketing purposes.
2. Can radar speed limit signs be installed on any road?
They are usually installed on roads where speeding is a common problem, such as arterial streets, near schools, construction sites, or in residential areas2. Installation must also comply with relevant traffic regulations and safety requirements.
3. How high should a radar speed limit sign be installed?
Generally, it should be installed at least 2.4-4m above the ground to avoid obstructing pedestrians and ensure clear visibility for drivers.
4. What are the common power supply methods for radar speed limit signs?
There are mainly three types: AC power supply, battery power supply, and solar power supply. Solar-powered ones are more environmentally friendly and suitable for locations without easy access to electricity.
