Ruck, 67, was stopped behind another car at the intersection of Hollywood Boulevard and La Brea Avenue on Halloween night when his Rivian R1T suddenly lunged forward and hit the car in front of him.
His truck then careened across lanes of traffic, hitting another vehicle before slamming into the wall of Raffalo’s Pizza.
No one inside the restaurant was hurt and no one was seriously hurt in any of the vehicles.
Ruck cooperated with police who quickly ruled out the possibility that the actor was intoxicated or had committed a crime, a spokesperson for the Los Angeles Police Department told KTLA.
He told witnesses at the scene that he had no idea what happened and expressed concern for those he hit.
According to TMZ, law enforcement sources believe the crash could be related to “the fact that Alan’s truck … is brand-spanking new and super high-tech,” the entertainment news site reported.
What exactly caused the truck to accelerate is still unknown.
KTLA reached out to Rivian for a statement on Tuesday.
“Our internal examination found no indication of malfunction and that the vehicle performed as designed,” a spokesperson said. “We are fully cooperating with local law enforcement’s ongoing investigation of the incident.”
