Traversing South African roads on a daily basis is already challenging – from avoiding potholes to unruly drivers, it’s an anxiety-inducing experience at the best of times. However, criminal syndicates are adding to the many risks motorists face as so-called highway gangs resort to placing rocks and, more recently, spikes (sometimes disguised in plastic bags, etc.) on the road. With the aim of damaging a vehicle to force the driver to pull over, then attacking the unsuspecting and stranded motorist and robbing them of their valuables, these incidents can easily result in something far more serious than simply a broken window or slashed tyres. It can lead to serious injury and, in some tragic instances, death.
