The bus matron whose vehicle was hit by a rental truck allegedly driven by West Side terrorist Sayfullo Saipov in last Halloween’s bike-path attack is suing the city for $5 million over her extensive injuries.

Marierose Charles was riding on the special-needs school bus with two students and the driver when Saipov allegedly barreled into them at West and Chambers streets on Oct. 31, 2017.

The impact flung Charles on top of one of the students.

“I heard a loud crash sound and the bus matron landed right on me,” the student, Noah Salz, told WABC in an interview last year.

Charles underwent surgery for fractured right ribs, lumbar spine injuries, a collapsed lung and damage to her right shoulder, her attorney Lawrence Krasin told The Post.

Her new Manhattan Supreme Court suit faults the city for failing to install barricades that would have prevented vehicles from entering the bike lane.

It wasn’t until the day after the deadly Halloween horror that city transportation workers finally installed concrete barriers at over four dozen intersections along the highway.

Saipov allegedly drove his rented Home Depot truck south along the West Side Highway bike path for nearly a mile before hitting the bus at the intersection that crosses the path.

The ISIS-loving Uzbek native has pleaded not guilty to murder, attempted murder and other charges. His trial is scheduled for October.

Other victims — including families of seven of the eight people killed — have already sued, making similar claims.

A city Law Department spokesman said, “We will review the complaint.”
