Question on Gatso markings

[hellsbuddha]

Just in case anyone knows it the old M41 between Shepherds Bush and the A40 has a camera northbound.

My question is does the camera work between the speed markings as I may have speeded up a little too early and definately saw two flashes.However I dont know if they were for me or the car behind. I reckon I had about 4 markings to go.

I realise I can wait for the NIP but any comments appreciated

cheers

If you get an NIP then request the pictures because if the second pic shows the car outside the markings then you can argue because there is no verifyable distance you have travelled for the given time between the flashes. you can work out your speed using s=ut.
