An enraged motorist brawled with a truck driver in the middle of the Staten Island Expressway — and bashed the trucker’s big rig with a baseball bat in a wild road-rage attack caught on camera.

Dashcam footage from the 4:30 a.m. Oct. 11 incident obtained by CBS New York shows the man behind the wheel of a Honda Accord driving erratically before stopping short in front of the tractor-trailer.

The bat-wielding Honda driver gets out of his car on the expressway near Clove Road in the Manor Heights section of the borough and approaches the truck driver, 42, who can be heard saying, “You just put your hands on me? You just put your hands on me?” as he jumps out of the truck, according to the footage taken from the truck.

The Honda driver comes at the truck driver with the bat, prompting the trucker to tackle the man on the road and fight amid passing cars, the video shows.

“You better not! You better not!” the trucker shouts at the man as he zones in on him with the bat.

Passing motorists eventually break up the fight — but the violence isn’t over yet, as the Honda driver then goes after the truck, bashing it, the footage shows.

The NYPD said the Honda driver smashed the truck’s headlight, driver’s window and driver’s side mirror with the bat.

The Honda driver remains at large and no arrests have been made, according to cops.
