Two days ago, on the way home saw a bus stopped by JPJ and the bus driver was given summon.

We (me and my sis) didn't have to ask the JPJ also can know what's going on - the heavily smoked bus was the answer.

Yep, very dark at the back of the bus.

And seriously, can those motorcyclist service their motorcycles so that they don't pollute the air?

It's dirty and hot enough in KL.
