 Both the tractor and trailer of Malaysian semi-trucks are fitted with the "Hazardous Cargo" registrations plates upon entry into Singapore.The same characters of the Malaysian number plates are used, with the only visible changes being the standardised fonts which reflect that of Singapore's and the colour code, which features black characters on an orange background.The "Hazardous Cargo" number plates subject Malaysian semi-trailers to the same laws followed by Singaporean ones.
