I am willing to bet the defendant is confused about the distance between the lines and the repeat distance. He will most likely be comparing the distance between the markings to that quoted for the repeat, the lines are 3-4" wide for that type of marking.
Seems like there has been a mistake in letting this chap go in my estimation.

As the markings are 5' apart not 12" the reading would be closer to 1.5% out not 25%.

How did you get that? 3 inches out of 60 is 5%.

I have no idea, thick fingers on the calculator or thick head on the shoulders perhaps.

Slightly O/T but I’ve asked the question before and no one seemed to know the answer. On the Managed sections of the M42 and now the M6 around Brum, on the road markings at the HADECS gantry locations, there appears to be a groove in the road surface– similar to a loop location – running up the middle of the markings. Any one any ideas ?

They are to automatically calculate the rate of traffic. Contrary to popular belief the speed limits are adjusted via an algorithm with the option of being overridden e.g. Camera monitor spots a crash and shuts a lane out.

My guess would be axle counters as many cameras have them to distinguish between different types of vehicles
