Radar Speed Signs

Road safety education with a smile

Radar Speed Sign GR33CL with smiley face

Reliable. Sustainable. Effective.

Radar Speed Signs reduce the speed and set a clear signal for road safety. In contrast to conventional signs, flashing LEDs reduce the habituation effect to a minimum. It works that simple:

• Warning

Draw attention to the essentials: the current speed, the road traffic and the associated dangers.

• Social control

Every road user can see how fast they are driving. This automatically creates the need to adjust the speed.

• Reward

Drivers who adhere to the speed limit will be rewarded with the smiley. This incentive is often enough to take the foot off the gas.

The speed display can be easily installed by one person - connect the power supply and off you go: ▶️

Extremely effective speed display from Sierzega. The drivers are motivated to stay in the "green zone".

Reduce Speed

The indication of the speed, which is visible to all road users, has an effect on almost all drivers, calms traffic and sends a clear signal for road safety.

Gain Attention

Radar Speed Signs shake drivers out of their daily grind and draw their attention to danger spots such as schools, pedestrian crossings, kindergartens or town entrances.

Deliver facts

"People drive way too fast here!" Have you heard that before? The integrated, anonymous data collection provides facts about the date, time and speed, which can be conveniently presented in diagram form.
