DF 11 Series
Portable compact driver feedback solution, ideal for quick relocation and install on existing infrastructure for temporary driver speed education campaigns on low speed roads.

DF11 driver feedback signs are installed to work in tandem with existing static regulatory and warning signage, and are targeted at specific drivers traveling above a pre-determined safe speed threshold.

DF11 employ microwave Doppler radar to detect vehicle approach speeds and uses 2 no. 11” seven segment LED characters to display driver speed.

Importantly the DF11 is not a replacement for static signage or to be used as a repeater - they are a speed targeted supplementary advisory device.
