Rock legend Peter Frampton was injured in a car accident earlier today … and claims it’s all because some “woman driver” was texting behind the wheel instead of watching the road.

Frampton vented about the situation on his Twitter page a few hours ago … explaining, “Texting woman driver just ran into back of me while I was stationary in traffic 101 freeway.”

He added, “Can u say whiplash? People put the phones down!”

The 62-year-old claims he sustained injuries to his neck and back … and says he plans to go to the hospital later today … after a flight.

FYI — texting and driving is now illegal in California … and violators are subject to some serious fines.
