 Although the general practice is to use white characters on black, stickers with colour schemes that resemble their original plate colours may also be acceptable; stickers that emulate the layout and colour of the Thai plates have also been known to be used.Malaysia-registered private vehicles are typically permitted to enter Singapore with few restrictions due to minimal license plate conflicts with Singaporean license plates as a result of their common lineage, with some exceptions from vehicles originating in East Malaysia.However, Kuala Lumpur's 2013-2016 extended W series plates (Wx #### x) had notably conflicted with the Singapore's W series for engineering plant vehicles and British-sourced 4×4s, Q series for government vehicles, S series for Singapore private vehicles and as such Malaysian vehicles registered in this W, Q and S series may be required to be further identified by their country of origin.
