It was the latest strike to grip Brazilian cities, including two World Cup host cities of Rio and Sao Paulo, where bus drivers also demanded higher salary and reduced working hours.
Unlike Rio and Sao Paulo, Salvador has not developed mature railway or subway networks, which means citizens do not have access to other transportation means.
Salvador, with a population of about three million, is set to host six games in the World Cup, including a round-of-16 match and a quarter-final.
The first match, Spain against the Netherlands, is scheduled for June 13.
With the FIFA World Cup less than three weeks away, the strikes aroused concerns over public transportation which is an essential tool to get spectators to stadiums since private vehicles will be banned from the vicinity of many host city's main stadiums.
