guys always pull ur handbreaks whenever ur car is on IDLE..
we normally only rely on gravity, which is very wrong .. keep all ur seat belts (even passengers) on and use hand brake when ur on STOP at chowks or else where otherwise this happens

another tip dont rely just on keeping the BREAKs pressed while ur at a STOP.. cuz even that is NOT enough
one last tip.. take off ur seat belts when you are re-fueling from a petrol station / CNG station ... cuz otherwise one can easily get trapped in seat belts in face of any fire emergency ...
may Allah keep us all safe.. Ameen
