A devastating collision on Tuesday, April 1, 2025, involved 28 vehicles near Edenvale in Ekurhuleni. Two drivers suffered serious injuries, and the traffic chaos was severe for commuters.

What happened on the N12 Edenvale Highway?
The multiple-vehicle accident occurred on the N12 Westbound just outside Edenvale, completely blocking both lanes. The accident involved over 20 cars, trucks and other vehicles, causing significant damage.
Emergency medical services (EMS), which responded immediately to the scene and treated those who were injured, assisted. Eight other people were treated on-site for minor injuries. Two drivers suffered serious injuries, and were taken to hospitals nearby for immediate treatment. Luckily, there were no fatalities, despite the chaos.


The N12 Westbound was closed for several more hours due to the complete blockage of the road. Emergency services and traffic officials worked to clear and secure the wreckage, which also affected the eastbound lanes. Traffic was backed up for many kilometres, causing significant delays to motorists.
Traffic disruptions and alternative routes
The accident caused massive traffic congestion, especially during morning rush hour. The emergency response teams worked tirelessly to clear up the accident scene and reopen N12 Westbound, but it was hours before the highway could be partially reopened. At midday only a small portion of the N12 Westbound was open, but traffic remained slow while cleanup continued.
The N12 was closed for several more hours. Motorists were advised to seek alternative routes and avoid the area. To avoid any further delays, those heading westbound are advised to take the R21 or alternative routes. The authorities warned that traffic would continue to be disrupted as the cleaning process continues.
Experts Weigh in on the Cause of the Crash
Experts believe that a number of factors may have contributed to this massive pile-up. The exact cause is still under investigation. Dr. Alan Louw is a road safety expert who suggested that the crash may have been caused by driver error combined with wet roads and low visibility.
Simon Zwane (RTMC spokesperson) shared his insights on the investigation. Zwane said that they were gathering footage from SANRAL CCTV cameras in order to better understand the events. The crash was caused by a sudden shift in traffic conditions that drivers could not react to.
The RTMC assured the public they are closely monitoring this situation and working to identify any contributing factor, such as road conditions, driver behavior, or mechanical problems with the involved vehicles.
Public Safety and Response Concerns
Many commuters in the area were stuck for several hours due to traffic. Some people have questioned whether the N12 highway is safe, given the increase in traffic in recent years. Experts are calling for better traffic management strategies in light of Gauteng’s rapid growth.
A local resident, who was impacted by the accident, said: “We must prioritize road safety and educate drivers about the importance to follow traffic rules during peak hours.” Better infrastructure and more clear signage could help reduce accidents such as this.
Official Updates on Recovery Efforts
Ann Makgatho, the Ekurhuleni Police spokesperson confirmed that two seriously injured drivers had been taken to hospitals nearby for emergency treatment. She said that emergency responders were on the scene quickly and they are grateful no one was injured. Eight others suffered minor injuries.
