Two cars crash in succession into self-propelled howitzer on dark highway; driver in their 20s killed

[Financial News]  A crash in which two civilian vehicles following an Army self-propelled howitzer collided with it one after another, killing one driver in their 20s, has come to light belatedly. The howitzer was returning to its base after training on an unlit national highway in Cheorwon, Gangwon Province. With indications that its rear marker lights were not clearly visible at the time, concerns have been raised that the military may have taken inadequate safety measures. 
According to Yonhap News Agency on the 10th, at around 7 p.m. on the 5th, a Kia Sportage passenger car and a Porsche passenger car collided in succession with an Army self-propelled howitzer (K55A1) traveling on National Route 43 in the Cheongnyangni area of Cheorwon County.
The Sportage driver, identified as A, 28, was killed in the crash, while the Porsche driver, identified as B, 57, complained of pain and was taken to a hospital. Some of the seven service members aboard the howitzer suffered minor abrasions.  
Dashboard-camera footage released on social media (SNS) and elsewhere shows that the crash site was dark because there were no streetlights, and that the lights at the rear of the howitzer indicating it was moving were not clearly visible to nearby vehicles.
Police, together with the Military Police (MP), are checking whether there are guidelines on the distance between vehicles and driving speeds when a self-propelled howitzer is on the move, and whether appropriate safety measures were taken. 
To determine the civilian vehicles’ speeds at the time of the crash, police have commissioned the National Forensic Service to examine the event data recorder (EDR) and are securing and analyzing CCTV footage from before the crash. 
Police plan to question those involved, including service members and commanders who were aboard the howitzer.
An Army official said, "Police are currently investigating the exact circumstances and cause of the crash, and the military will actively cooperate with the police investigation."
