Hi 
OverLimit between 20 - 30 KM/H is 6pts, correct leh. I kenna in Feb
this year and that's what I got. Was doing 80+ on a 3-lane straight
wide road. Kenna orkong then realised that the speed limit is 60.
Cannot take it. You kena late at night, right? Daytime nobody
follow those ridiculous limits, TP don't even bother to
enforce.
Just checked spf website : Still stated as 6 points also.
Assume you already double-check the prinout that the TP punch in
the offence correctly?
Call and check. If they make mistake, good chancce to KPKB at
them.
Good Luck!
