No offence.
As long as the front wheels of your vehicle crossed the line ( I.e. Beginning of the Junction ) before the lights turned red . It does not matter even if your path is blocked.
However, if the lights turn red, and your car's front wheels then cross the line, you should stop your vehicle immediately.
If you continue to cross the line into the Junction , you would be deemed to have intentionally tried to beat a red light, when your back wheels cross the line .
This is based upon my actual experience at junctions with red light cameras.
For the first scenario, I did not receive any traffic summons.
For the 2nd Scenario, the lights turned amber just when the front of my car was at the line. I could not stop in time, so the front wheels crossed the line at a red light . But I stopped my vehicle. So the back wheels did not cross the line.
To keep it simple, if you have any doubts, just stop your vehicle.
The TP analysing the photos would be able to read your intentions and understand that you did not intentionally want to beat the red light.
A questions for experienced Drivers...Assume a huge junction. A car enter the junction at green light, halfway in the middle of the junction the light turns amber.About 2 seconds later it turned red and the car was 1.5m from crawling out of the junction (cos traffic jammed up in front).
Is this considered as an offence?
