The teen was crossing state Route 1 outside a marked crosswalk or controlled intersection just south of Tamalpais Junction around 2 p.m. Thursday, CHP Officer Chris Rardin said.
He was struck by a 2010 Mercedes GLK 350 that was traveling 25-30 mph on northbound Route 1, Rardin said.
The teen failed to yield to oncoming traffic and ventured directly into the path of the Mercedes, Rardin said.
He was thrown to the ground and landed within the left lane of northbound Route 1, Rardin said.
The boy was taken to Marin General Hospital. The left front quarter panel and hood of the Mercedes were damaged in the collision, Rardin said.
Pedestrians are required to yield the right-of-way to oncoming traffic when they are crossing a street outside a marked crosswalk or controlled intersection, Rardin said.
