A 21-year-old motorist died after crashing into a tree on South Union Road near Peach Avenue in rural South Manteca.
It was one of three mishaps Friday afternoon.
There was a three vehicle rear end collision on Union Road at Wawona Avenue some two miles north of the fatal crash.
Shortly after 4 p.m. a 15-year-old teen collided with a westbound pickup truck near a crosswalk.  The girl received abrasions and bruises from the incident, Manteca Police said. She was transported to Doctors Hospital in Manteca for observation and treatment
Also, a northbound 2006 Toyota SUV crashed off the end of the Highway 99 Frontage Road and rolled over onto the railroad track that parallels French Camp Road. CHP officers said the 24-year-old motorist from Stockton was traveling about 60 miles per hour on the Frontage Road when he reached a curve in the road and ran off the road into weeds where he rolled his vehicle that caused the death of his pet dog while he only complained of neck pain. The rear end of his car landed across railroad tracks that parallel French Camp Road. The railroad dispatcher was called and advised that there was a vehicle partially blocking the rails.  The motorist is being charged with driving under the influence, officers said.  He was transported by ambulance to San Joaquin General Hospital where he remains in the custody of the hospital.  His 2006 Toyota SUV received major damage in the crash. CHP officers took a small jar of marijuana buds from the vehicle during their investigation at the crash scene.  A tow truck driver placed a blanket over the body of the small dog where it was thrown from the car and died.
