The move was announced after a city bus on Tuesday hit four parked vehicles and a lamppost in Warsaw's north-western Bielany district. A female passenger was taken to hospital with bruises.
Police said the 25-year-old driver tested positive for methamphetamine and was detained.
Meanwhile, in a dramatic accident last month, a bus plunged off an overpass in Warsaw, killing one person and injuring over 20.
The driver of that vehicle had been driving while under the influence of amphetamines, the Warsaw prosecutor’s office said.
The man faces up to 15 years in prison. Forty people had been aboard the bus at the time.
