NERDS star ROBERT CARRADINE nearly totaled in gruesome head-on collision – cops.

Robert, 60, the younger brother of Keith and the late David Carradine, was involved in a terrifying car accident with a semi-truck.

The collision occurred last week on a Colorado highway.

According to the police reports, the “Nerds” star slammed into the truck head-on.

“He was northbound on Highway 145 and drove right into the oncoming lane,” said CSP Sgt. James Saunders told TheCortezJournal.com.

“There were no apparent contributing factors.”

Both lanes were closed for more than two hours after Carradine’s 2003 Mercury Marauder collided with a southbound 2014 semi at 2:17 p.m. on Thursday, March 5, police confirmed.

Luckily, both Robert and his wife, Edith, were both wearing seatbelts. Neither and speed nor alcohol were not a factor in the crash, according to the state patrol. Both were transported to the hospital with serious, but non-life threatening injuries. They were then transferred to Mercy Regional Medical Center in Durango.

“The fact that they were wearing seatbelts is why they are with us today,” CSP Sgt. James Saunders said.

A spokesperson for Mercy Regional Center said today that neither Carradine were currently patients. The driver of the semi was injured, cops said.

After making his acting debut with John Wayne in “The Cowboys”, Robert starred with both his brothers in the western “The Long Riders” before achieving notoriety in the popular “Nerds’ films in the 1980s. He is the son of the legendary character actor John Carradine.
