An often impenetrable logjam of trucks laden with coal at South Africa’s crossing with Mozambique has brought chaos to a sleepy border town. Elephants escaping from the nearby Kruger National Park often caused the biggest commotion in Komatipoort. These days residents check their CCTV cameras on their phones at barbecues on the weekend. The congestion created opportunities for criminals who saw drivers stranded in the queue for days on end as easy targets after nightfall. Robberies, theft and assaults spread from the highway to the town. Road accidents increased.
