Two drivers died on a South Korean highway after an 8.5-ton freight truck struck the scene of a previous collision [1].
The incident underscores the extreme danger of secondary accidents, which occur when vehicles collide with existing wreckage or rescuers on the road. These subsequent crashes are significantly more lethal than initial accidents, often occurring when drivers fail to notice hazards due to poor weather conditions.
The sequence began when a frozen-truck collided with an SUV that had stopped on the shoulder [1]. While individuals were attending to the scene, the 8.5-ton freight truck struck the area, killing both drivers on site [1, 2].
Local authorities attributed the tragedy to heavy rain, which severely reduced visibility for motorists on the highway. Han Seung-bong, chief of Gangwon Police District 7, said the driver of the large vehicle likely failed to see the accident vehicles in front of them [1].
According to police data, the fatality rate for secondary accidents is approximately five times higher than that of ordinary crashes [1]. The severity of these incidents is often amplified by the speed of the highway and the lack of visibility during storm events.
Police officials said that drivers should prioritize immediate evacuation from their vehicles over assessing damage after a crash. Because secondary collisions occur so rapidly, moving away from the flow of traffic is the only way to ensure safety during the rainy season [1].
“The fatality rate for secondary accidents is approximately five times higher than that of ordinary crashes.”
This tragedy highlights a critical failure in highway safety during extreme weather. The five-fold increase in fatality rates for secondary accidents suggests that traditional roadside assistance protocols are insufficient when visibility is compromised. It reinforces the necessity for immediate evacuation zones and the use of high-visibility warning systems to protect both victims and first responders from oncoming traffic.
