OP, let's just deal with the evidence which, as I understand it, is solely the CCTV.
This shows your car and then cuts away and returns to your car.
While your car is first in view it is moving, albeit slowly. It had not stopped at 8.31.597.
The next shot of your car shows it stationary between 8.32.03 and 8.32.08.
The CCTV does not show the car stopping. It is therefore impossible to know for how long it was stopped other than this could not have been less than 5 seconds.
There seems to be a passenger in both clips.
OP, as you were stationary let's not dance around this. IMO, your reps should focus on the brevity of your stop. For our purposes the why might be helpful.
You seem to be talking to your son and then looking at the school entrance. Does your son attend there normally/is this the entrance you use normally/were you expecting the same this time but couldn't see the entrance gate open/what did you do to 'check directions'?
OP, you posted: I stopped for 2 minutes to check directions.
Having now seen the clip what would you say?
