Three people were injured, one seriously, in a three-car collision on Tuolumne Road at Cherokee Road on Wednesday night.
The California Highway Patrol said Cheryl Baker, 62, of Tuolumne, caused the 8:42 p.m. wreck when she turned left in a 2003 Honda from the eastbound turn lane of Tuolumne Road directly into the path of a westbound 1988 Mazda pickup driven by Jackson Trent, 16, of Sonora.
Both vehicles ricocheted off the front of a 1988 Toyota pickup stopped at the stop sign of Cherokee Road at Tuolumne Road. The Toyota was driven by Nathan Reese, 21, of Sonora.
Baker sustained major injuries. She was arrested on suspicion of driving under the influence of alcohol or drugs and transported by helicopter to Memorial Medical Center in Modesto.
Trent and a 16-year-old male passenger in his car were taken to Sonora Regional Medical Center for treatment. Reese was not injured.
Officer Marc McWilliams, of the California Highway Patrol Fresno Traffic Management Center, said the roadway was cleared at 10:04 p.m.
