Hello there, please be all advised that near the pedestrian pass there are sensors underneath the asphalt mant as to detect movement .

If you park on those sensors even if you make a full stop it will trigger the cameras and you will be flashed.

So it could be that.....or the one going in front of you was in such a hurry that activated the cameras and then he/she was flashed.

Just go to moi.gov.qa and check...otherwise be prepared to be fined and for less points on driving license.

Best regards
