You cannot compare our system with theirs. There, if you are caught (insufficient money in the cash card to deduct toll charge, defective card reader in the car, etc), their land transport authority will send letter to your house to either pay the toll charged plus penalty, or send your vehicle for inspection if the system does not detect your card reader in the car. You cannot ignore the letter because the consequence is severe - can be charged in court.

Here? Who is going to help TnG collect the unpaid toll if drivers do not have to go through toll gate and simply drive off? Issuing summon/letter won't work because people will just ignore it. If JPJ/polis summon can be ignored, what chance does TnG have in recovering the owed money?

You ask me, I don't know who to ask.

Is the lane specially for RFID or shared with smartag? If you took out your smartag, how will you know which system will charge your toll?

I see.
The RFID signboard on shared lane is a bit small though.

It's strange that the installer agreed to fit on your tinted headlamp. Mine die² refused to do so, ended up sticking on outside of windscreen. It's supposed to be SOP to avoid people cutting off the tint film to transfer to another car, according to the installer.
