if u need to move around in KL/Johore (state or JB? there's a
difference) then having ur own transport will be gd.
if its only for a day max. biz trip, then u might want to
re-consider if its worth driving over as u need to fulfill the 3/4
tank rule (+ other petrol expenses) and ERP/toll fee (minimal).
accident rate over in JB and Johore state is rather minimal...just
be more cautious when driving up north.but of course, all these
should be able to recover back as its biz trip.
highway code...same as ours...u need to know what's AWAS and some
other malay language road signs though. otherwise, all the way to
KL is pretty smooth.
as for TP, the rule of thumb is, if u dun speed, u won't kena so
easily. otherwise, if they die die want to makan u, stop, bargain
abit (abeit fishing) and pay up n leave. what my fren did was to
pay the TP n have them lead him all the way up north...highspeed n
non-stop. u PR got to be reasonably ok.
have a safe n gd trip.
