Thanawat Kachaban has confirmed his intention to quit the route, Jittra Srirungruang, deputy managing director of the Bangkok Mass Transit Authority (BMTA), was quoted as saying by Daily News Online on Friday.
Ms Jittra said she could not guarantee that the 25-year-old driver would be behind the wheel on other lines but said he had a licence to operate public transport.
The driver put himself in the spotlight after driving Route 8 bus number 36-115 into the left side of a car in the right lane and pushing it to a standstill on the island in front of Chatuchak Park on Phahon Yothin Road outbound on Thursday.
The incident and pictures were oposted by a Twitter user named @jirasak, who said it caused panic among passengers. The message was quickly followed by responses condemning the driver.
The images were taken from a car behind the vehicles.
The incident was the latest black mark on the already infamous reputation of the bus route that runs from Memorial Bridge to Happy Land.
Operated by the subcontractor Thai Bus Transport Co, the route was declared the most dangerous route by passengers sending complaints to the BMTA last year due to the bad behaviour of drivers and conductors.
Caretaker Transport Minister Chadchart Suttipunt, a regular bus rider, on Thursday ordered Mr Thanawat not to drive until Monday and to be summoned to the BMTA for investigation on Friday. The bus was also ordered not to service passengers for the same period.
