South Africa is preparing for a potential vehicular chaos on December 15, 2023, due to a rare combination of events, including the Rugby World Cup victory, the end of the school year, and a drop in fuel prices. The South African National Roads Agency warns that the N1 toll road, N3, and N4 will be the busiest during this time, with potential accidents and delays at toll roads. Travelers are advised to consider alternative routes or driving on Christmas Day and Boxing Day to avoid this historic traffic surge.
