The crash occurred in the left lane of Route 31 north just prior to West Main Street (CR 513) in Clinton Township around 6 p.m., Police Administrative Division Commander, Lt. Harry P. Bugal Jr. said in a release.
The driver of the first vehicle rear-ended a vehicle stopped in traffic, which then rear-ended another vehicle that was stopped in traffic, Bugal said.
The driver of the second vehicle that was rear-ended — a 64-year-old man — was airlifted to Morristown Memorial Hospital for treatment, police said.
The other drivers, a 28-year-old and a 39-year-old man, refused medical attention.
All three of the vehicles had to be towed from the crash scene, and the 28-year-old man was issued a summons for careless driving and driving an unregistered vehicle.
