Description of events and explanation of diagram
I
My vehicle is travelling in the outside lane @ approx. 40mph
In my rear view I can see nothing behind me in my lane and a normal flow of traffic in the middle lane

II
Traffic Signal switches from Green to Amber
My vehicle is travelling I the outside lane @ approx 40mph
In My rear view I can see an ambulance with lights (no siren) moving from behind a Van to the outside lane behind me
Traffic in my forward view continues through amber signal

<1.8 seconds from II
I make the decision not to stop in front of Ambulance blocking his path and halting his progress
I identify blue people carrier slowing for lights in middle lane
I make the decision not to perform an emergency stop and pull in behind people carrier in middle lane as I believed this would be a dangerous manoeuvre that does not warrant the risk involved.
I identify that there are no haazards associated with crossing the junction
I make the decision to continue at my present speed and cross the junction in a safe manner believing that I will begin to cross the junction before the signal turns red; however I still know that even if the light does turn red there will still be no danger associated with crossing the junction.

III
I begin to cross the junction, believing that I have crossed the junction before the light changes to red; however the photographs show that this is not the case.
All other vehicles stop for the red light
The Ambulance turns on his siren and proceeds to cross the junction behind me

Once I am across the junction I move to the middle lane allowing the ambulance to pass on the outside safely and continue my journey as normal.

Key points:
I have paid proper attention to the hazards associated with crossing the junction and concluded that there is no risk.
Any attempt to stop for the light would have ended in either a dangerous stopping manoeuvre, or blocking of an emergency vehicle on call.
I made no attempt to accelerate through the junction in order to “jump the light”
I did not at the time believe it was an offence to cross a red light, it is only after I have researched into this that I have discovered that it is still considered an offense, and according to the law I should have stopped in front of the vehicle blocking it’s path
I full accept that I have committed an offense, however I wish to highlight the reasons for committing this offense to show that it was not due to lack of neither attention nor haste.
