RTMC spokesperson Simon Zwane said a team from the corporation, the transport department's agency responsible for road safety, will be working with other law enforcement authorities to investigate the cause of the crash.
Zwane said a team of RTMC crash investigators rushed to Jozini, in northern KwaZulu-Natal, earlier this month following a horror truck accident. In that incident, on June 10, a driver lost control of the truck and crashed into vehicles and pedestrians. Eight people died and 32 were injured.
Zwane said the many avoidable crashes put a strain on the health-care system, which was already overburdened by Covid-19.
"We urge motorists to drive with caution, especially during the winter season. This is the period associated with a high number of crashes because of poor visibility, caused by mist in some parts of the country and veld fires."
