Deputy Transport Minister Athirat Rattanaseth has instructed the Marine Office in Nonthaburi province to regulate the operations of jet skis on the Chao Phraya river, to improve safety.
Mr Athirat gave the order during an inspection trip to the Marine Office of Nonthaburi on Wednesday morning.
It follows complaints jet ski riders are annoying riverside residents.
People complained jet ski riders were going at high speed and performing stunts on the river, obstructing water traffic and making excessive noise, particularly during holidays.
There are currently 162 jet skis registered with the Marine Office of Nonthaburi.
Mr Athirat ordered the office to strictly enforce the law pertaining to jet skis, regularly check licences and registration, and issue orders regulating their operations.
He also wanted the office to improve the Nonthaburi wharf, to make it a "smart" pier.
