Try driving to Kuala Selangor then u can see a clearer picture. The roads are small n lorries always hog the roads. What do other drivers do? They overtake of course. But, at the same time, many motorcyclists also use the same road.
Same goes for roads in Malacca... in fact, any small town.
In this case, maybe this Proton Iswara driver overtook a lorry but didn't realise the victims' motorcycle is in front of the lorry n immediate put out an emergency brake n CRASH! BOOM! BANG!
Oh well... life still must go on!
RIP to the victims.
