Nineteen people died on the R28, near Westonaria, yesterday when a taxi collided with a truck. The taxi rolled and burst into flames, according to ER24 spokesman Chitra Bodasing.Passengers were flung from the vehicle.Five people survived, but four, including a young child, were in critical condition.It is believed the taxi was overloaded and the driver may have lost control of the vehicle.The truck driver suffered minor injuries.Gauteng traffic police spokesman Obed Sibasa said the authorities believed the taxi was carrying more than the legal limit of 16 people.He said a burst tyre was a likely cause of the crash.Bodasing said paramedics were faced with a horrific scene when they arrived as bodies were scattered across the road.The R28 was closed for most of yesterday afternoon as officials investigated the scene.It is not "speed that kills but greed that kills", said Howard Dembovsky, founder of NGO Justice Project.He said usually taxi drivers were not the owners of the vehicles they drove and could make extra money by overloading it."The tyre could have been in perfectly good condition, but tyres are designed for a certain weight and cannot withstand excessive weight," he said."How can a driver be expected to control the vehicle when the vehicle is overloaded? Most crashes occur because of lack of enforcement."Department of Transport spokesman Sam Monareng said: "We are concerned about overloading of any vehicle."President of the SA Taxi National Council Philip Taaibosch said if a taxi driver overloaded his vehicle and an accident resulted, the driver should be arrested for murder...
