According to Section 12 in conjunction with Section 60 of the Act, offenders may face a fine of up to B2,000, said a Royal Thai Police notice shared by Patong Police earlier this week.
The regulation aims to ensure road safety and prevent accidents caused by visual distractions or impaired visibility for other drivers.
Pol Lt Gen Sirawat Deepo, Deputy Spokesperson of the Royal Thai Police, emphasised the serious consequences of such modifications.
If alterations result in accidents causing injuries or fatalities, offenders could face charges of negligence under the law, Lt Gen Sirawat announced in the notice.
The severity of penalties will depend on the outcome of the incident, ranging from causing physical or mental harm to severe injuries or even death.
A recent case highlighted the enforcement of this law when the Central Investigation Bureau apprehended an individual identified as Riwat Tee for violating these provisions, Lt Gen Sirawat noted.
Police are urging vehicle owners to adhere to legal regulations and avoid unnecessary modifications that may jeopardize road safety, the notice said.
“Our goal is to promote responsible driving behaviour and reduce the risk of accidents,” the notice added.
