mmda and traffic light

[sparks]

This may be a dumb question but.. I was just wondering.. how do the mmda personnel 'know' the traffic light has turned 'yellow' if they're not facing the traffic light, even behind the traffic light?

In case a car was beating the 'yellow' light, is it because when the traffic light turns yellow, the other cars are already stopping? Or is it that they use some other hint?

Good question.

MMDA personnel wouldn't know if its yellow unless they are facing the traffic light.

In case a car was beating a yellow light there wouldn't be a traffic violation because yellow light simply stands for "slow down the light will turn red in the next second."
