The illuminated ice-warning pavement markers:
(a) must be approximately of the same shape and size as standard raised, reflectorised pavement markers;
(b) must illuminate and display a blue light when the road surface temperature reduces to a point that the formation of frost or ice is possible;
(c) may flash on and off at a rate of approximately 2 Hz to indicate the possibility of frost or ice on the road surface;

(e) must be installed on a centreline or no-passing line at intervals no greater than 100 metres at the trial locations;
