The Flame Pit / Re: M5 speed cameras
« on: February 16, 2026, 10:56:28 am »Hi all,From Cribbs Causeway (jn17) to Almondsbury (jn16) is covered by variable speed limits and Hadecs cameras. It doesn't look that far on the map but seems to go on for ages when driving. I've found the gantry signs can be easy to miss due to concentrating on the sheer weight of traffic especially going south. I've seen camera activations along there, not sure of the outcome, it's just a waiting game I'm afraid, 14 days of watching the post ...
First time posting so be gentle.
I was driving back from Weston on the M5 yesterday, staying between 60/70 and I noticed that on 3 separate occasions there was a flash behind me. Im pretty sure the stretch of the M5 is variable and no gantries were lit.
My question is, do speed cameras usually go off for no reason? I don't usually drive on motorways and not sure if it's something to do with calibration or a random trigger to remind people that they are actually there?
Just found it really weird that they went off for no apparent reason.
