The news made a special effort to point out that the 56 year old cement mixer driver was a Singaporean.
They were afraid that if the driver was a foreigner, then it can cause another uproar.
Actually this accident is a systemic failure.
Long ago, the PCR (pedestrian crossing rules) were put in place to allow motor vehicles to turn and drive across a pedestrian crossing at the traffic lights; provided the driver can see that there were no pedestrians - even when the GREEN man was still blinking and in favour of the pedestrians.
The rationale for this rule is to allow motor vehicles to drive on and not hold up traffic.
Before that change, all cars have to stop and can only drive on when the traffic lights change - regardless of whether there were pedestrians crossing or not.
So now, the important phrase is "provided the driver can see that there were no pedestrians". This is a left turn.
If the driver is in a tall and huge cement mixer and is in a rush to deliver cement to the work site, he may not spot the pedestrians.
It could be a blind spot and if he has no assistant sitting on the left hand side, the driver on the right driver's seat may not see.
Instead of slowly inching up at the turning to check whether there were pedestrians; the driver may have assumed that most people would give way to a behemoth even if the pedestrian crossing light was in their favour.
