you can choose not to display it, but you must be able to
produce it if the authorities request for it (ie spot check,
roadblock).
some pple say if dun display will kana $30 fine. however, LTA did
not mention this when someone wrote to the cut waste panel
questioning the rationale of displaying the road tax disc.
This was the reply from LTA:
We feel that it is still useful to issue the road tax disc, as it
is the most convenient way today to remind motorists of their
vehicle?s road tax expiry date. Also, for those driving to
Malaysia, the road tax disc serves as a proxy for the Malaysian
authorities to ascertain that a Singapore-registered vehicle is
properly licensed and has valid insurance coverage when entering
Malaysia.
