Dartford tunnel red light cameras

Going through the lights at Dartford approaching the tunnel northbound. There are 2 sets of lights. It’s likely I was going over the line as it changed to red on the second set. Panicked and didn’t think I could stop in time. I was only in a van at least so wouldn’t take as long to clear the line. There is a camera by the 1st set of lights for each lane so 4 in total. Do the cameras catch people going through both sets of lights or just the 1st main set. Just trying to work out if Ill deffo be getting a ticket. Thanks

Don’t panic mate, it will just catch first one. Camera always catching first set of traffic light. If there is no camera for second set. Then u are all right.

Hi im more of the opinion that they are more for overheight or haz loads than speeding ( cant be sure of course ) and then diverting the offender to the naughty step area to await a show trial and be hung drawn and quartered in dartford market place as example to others
