Four dead, several injured after semi carrying milk crashes into seven vehicles and catches fire on Loop 202 near Van Buren Street in Phoenix, Arizona
The semitruck traveling east on Loop 202 Red Mountain Freeway around 10 p.m. didn't slow for traffic congestion and collided with passenger vehicles in the area of 52nd and Van Buren streets, according to a Department of Public Safety news release.
Among the issues that NTSB investigators will study is whether the crash could have been prevented if the tanker was equipped with electronic safety devices, said board spokesman Chris O’Neil. “Automatic emergency braking is definitely something we want to take a look at,” he said.
Along with the Arizona Department of Public Safety, the safety board continues to investigate what prevented the semitruck from slowing down. Initial reports dismissed driver impairment.
