A Temecula teen riding against traffic on Rancho California Road Thursday evening was struck by a vehicle and seriously injured, authorities said.
Lionel McGee was listed in stable condition with major head injuries when struck by a vehicle on Rancho California Road, at Margarita Road shortly after 9 p.m., according to Riverside County sheriff's Sgt. Geoff Green.
The sergeant said that McGee, 18, rode in front of a vehicle making a left turn onto Margarita Road, from Rancho California.
"Last night a teen ... was riding across the street on his bike when he was struck by a car," resident Dustin Vangeison wrote to Patch in an email.
"I didn't see it happen; however I jumped out of the car and started doing first aid.
"Another man pulled up in his car and as it turns out he was EMS. When I got out it was 9:10 p.m. and there were only a few people around. The accident must have happened only minutes before," Vangeison wrote.
McGee suffered serious head injuries, the sergeant said.
