Four people died and a fifth was hospitalized after a truck with five young people in it didn’t stop at a stop sign and was hit by a semitrailer truck Monday morning, police said.

A Ford F150 with five occupants, all under 20, was traveling north on County TT. The driver failed to stop and a stops sign and the pickup was hit by an eastbound semi-truck.

Police said the three of the occupants of the Ford died at the scene, including the 19-year-old driver and two passengers, who were 17 and 16 years old. The 19- and 17-year-old were from Sun Prairie, a suburb of Madison, and the 16-year-old passenger was from Madison.

An 18-year-old woman died at the hospital after the crash and another passenger, an 18-year-old from Madison, was in the hospital with life-threatening injuries, police said.
