A Queens motorist and a truck driver were busted after a road- rage incident Saturday on the Brooklyn-Queens Expressway.

Ice fell from a truck and cracked the windshield of Artur Kieliszek’s Mercedes in Brooklyn, cops said.

Kieliszek, 35, of Ridgewood, sped up and passed the truck.

Then he pulled his car in front of the truck and hit his brakes.

That led the truck driver to slam on his brakes.

A livery cab slammed into the truck from behind.

Then a tractor-trailer slammed into the livery cab.

The cabby was treated at a nearby hospital for minor injuries.

Police arrested Kieliszek on reckless-driving charges and the tractor-trailer’s driver, Celso Gonzalez, 26, of College Point, Queens, for possession of drugs.
