Faulty Speed Camera M4-2493B - Jcn 10-8/9 Eastbound

Reported via mobile in the Sign issue (NH) category anonymously at 15:45, Fri 28 October 2022

Sent to National Highways less than a minute later. FixMyStreet ref: 3921604.

I traveled through the variable speed camera at 09:30 on 23/10/2022 and when I passed under the overhead sign it definitely read 60mph, as myself and my passenger had been very carefully monitoring the signs, using speed limiter and were particularly cautious due to the very poor driving conditions. As we came out the other side of the gantry we were both surprised to notice a double flash from a camera as we knew we had not been travelling above the speed shown. The following sign we came to did go down to 50mph and I again adhered to the limit. On my return from London on the afternoon of 25/10/2022 I noticed that virtually every vehicle on the Eastbound carriageway was getting flashed by the same camera as we had been through on 23/10/2022, it is hard to imagine so many people were ignoring the speed sign and can only conclude there must be a some technical problem and a review of variance in numbers flashed compared to normal might highlight the situation? I have today received a fixed notice, which will be impossible to contend without going to court, which I will not be doing. From what I saw there must be an enormous number of other drivers who have also been caught out by what I have to suggest is a fault and I would request this matter is investigated urgently.

  • I've got a notice for M4-2493B as well on 7th of November saying that I've exceeded a variable of 40 MPH speed limit in an area where the speed limit is 60 MPH.

  • Think I got caught on this speed camera coming back from Bracknell last night. Was not doing over 70 mph I did notice the double flashing. Braked and looked at the speed odometer it was under 70 MPH it was 70 on my sat nav system.
