Effective! The speed limit for all roads in BKK to not more than 60 kilometers/hour, except for 13 routes

On December 24, 2024, the Government Gazette website published a notice of regulations appointing the Metropolitan Police Commissioner or the person assigned to act on behalf of the Chief Traffic Officer in Bangkok. Therefore, the regulations are as follows:

This regulation is called the “Bangkok Traffic Chief Regulation on Speed Limits and Noise Prohibition in Bangkok 2024.”
This Regulation shall come into force from the day following the day of promulgation in the Government Gazette onwards.
The speed limit of the car does not exceed 50 kilometers per hour and noise is prohibited around the royal court area, including:

Ratchadamnoen Nai Road

Na Phra Lan Road
Sanam Chai Road
Kanlayanamaitri Road

Limits the speed of cars on all roads in Bangkok to no more than 60 kilometers per hour, except for the 13 main roads that are defined as follows:

This regulation applies to vehicles whose speed limit in the Ministerial Regulations does not exceed 45 kilometers per hour.
Abolish any notice or regulation that contradicts this new regulation, except for the Bangkok Metropolitan Area Traffic Authority regulation on the speed limit 2018 and the Bangkok Metropolitan Area Chief Traffic Officer Regulation on the speed limit and noise prohibition of the area around the royal court (901 land), 2021.

The announcement was signed by Police Major General Thawat Wongsangaล, Deputy Commissioner of the Metropolitan Police, acting on behalf of the Metropolitan Police Commissioner and the Chief Traffic Officer in Bangkok.

Reasons for limiting speed on roads in Bangkok

Police Major General Thawat Wongsanga, deputy commissioner of the Metropolitan Police (traffic supervision), explained that the speed limit in Bangkok was originally set at no more than 50 kilometers per hour in the royal court area, but the new regulations added “Na Phra Lan Road” to this speed limit area.

Other roads in Bangkok that previously had a speed limit of not more than 80 kilometers per hour have now been reduced to not more than 60 kilometers per hour. The main reason is to reduce accidents and improve traffic discipline for road users, as Bangkok is one of the highest accident numbers cities in Asia.

Police Major General Thawat said the new regulation was jointly studied with related agencies before implementing it. The goal is to reduce road accidents, especially during festivals such as New Year’s or Songkran, where the traffic is not jammed, causing accidents to happen easily.

However, this regulation excludes 13 roads connecting the perimeter, which still allow no more than 80 kilometers per hour because they are still safe to operate. Expressways and elevated roads are still subject to regulatory speed limits.

In addition, motorcycles are subject to this new speed limit to ensure the safety of shared roads.
