Jika pemandu memandu secara berbahaya, sila hubungi 09-862 XXXX / 09-862 XXXX.

Approximately translated into:

“If the driver drives dangerously, please call 09-862 XXXX / 09-862 XXXX”

I’ll be dead by the time the phone receiver system puts me on hold, the operator answers the call in the order it was received, files in the complaint, and notifies the right correcting authority.

If the driver is really driving dangerously, what I’m going to do is ask the driver to stop the vehicle and let me out.

And by the way, there is no such “merbahaya”. It should be “berbahaya”.
