If they want to have access to operate, all buses and heavy goods vehicles over 3,500kg must install a speed limit control device (SLD) on their vehicles starting July 2026. A notice issued by the Ministry of Transport (MOT) today explained that the requirement is in line with the country's goal to reduce the risk of accidents due to irresponsible actions among a few drivers in this category.
According to information, buses and lorries registered from 2015 onwards must install SLDs approved by the authorities and submit reports every two years, starting October 2025. And this enforcement has been implemented for new vehicles since 2015.
For vehicles registered before January 2015 with SLDs, the device must be activated and also submit a compliance report. These vehicles must comply with the regulations by January 2026.
With this information, it is hoped that all vehicle service operators are aware of this requirement and for the general public's information, MOT also announced that the speed limit for heavy vehicles will be standardized at 90km/h, even though the speed limit on highways is set at 110km/h.
