For safety reasons, the Thailand Transport Ministry has announced plans to limit speed for big bikers, as well as prohibit lane splitting for motorcycles above a certain engine size. This was reported by English language Thai website udona2z where a limit of 80 km/h is proposed for big bikes in built-up areas.

According to Thai authorities, big bikes will be prohibited from lane splitting and will have to wait in lane with other traffic. They will also be limited to a maximum speed of 80 km/h, said the unnamed source.

Additionally, the ministry will require riders of big bikes to obtain licenses specific to the capacity of the motorcycle they are riding. Riders will undergo special field tests and require to adequately handle simulations of dangerous traffic situations.

For foreign riders, it will be compulsory to show motorcycle licenses before being allowed to rent big bikes, which was not previously required. From the report, fatalities involving foreign riders has risen over the past years, mainly involving speed or riding under the influence.
