The camera always flashes at your back... that's how the sensors
work... only after they sensed that you have beaten the red light
will they flash at you so there's no way they can anticipate that
you will beat the red light and flash from the front....
Anyway, i think i know which red light camera you are talking
about... you are heading towards upper thomson road right? I've
seen that camera activated twice before (on other cars lah... haha
not mine)... The problem with that junction is that it is a super
small junction and the amber-to-red transition time is very very
short... so when you thought it was still amber, it might have been
red to the sensors already....
Wait for the letter lor... are you sure there was no car behind
you? maybe it was that car who got caught? Anyway, if you really
get the letter, i think the fine is about $200 and a 12 points
demerit leh... hope you're not a p-plate driver... My frens also
said that if you want to argue your case, you will have to pay more
to request them to show you the photo...
