A Joburg firefighter was left fuming after she was unable to reach an accident scene in time because other drivers had block up emergency lane."Hang your heads in shame!" Kim Williams wrote in a Facebook post that has since been widely shared.She believes some of the victims could have been saved if emergency services had arrived at the scene earlier.“I even got out my car to ask a guy to move a bit so I could get through. He told me to ‘f*** off’ then purposely turned his wheel to block me.Six people died in the crash, including a two-year-old boy. The accident occurred when a minibus taxi collided with a barrier near the Buccleuch interchange on the M1 in Johannesburg on Thursday.“What if that was your wife, your mother, your father, your sister, your son , your child lying there.“We might have saved them… if you had not broken the law,” Kim wrote on Facebook.She even urged JMPD to start arresting people who drive in the emergency lanes and in so doing prevent them from saving lives.@CityofJoburgEMS Accident along N1 South before Buccleugh interchange in Midrand with multiple injuries/fatalities @CityofJoburgZA pic.twitter.com/zSOMvpN3cl— Cojems Spokesperson (@RobertMulaudzi) September 28, 2017According to ER24 spokesperson Russel Meiring, five people were killed at the scene and the sixth victim died later of injuries.The number of injured and exact cause of the accident is still unknown.
