Five people were killed in a two-vehicle smash-up that caused their ride to flip over on the Cross Island Parkway in Queens early New Year’s Day, authorities said. 

A Mazda sedan was heading north on the expressway “at a high rate of speed” when it rammed into a curb and overturned around 6 a.m., police sources said. 

Then, a man driving a Honda in the same direction slammed into the Mazda near Exit 36S, cops and sources said. 

Four adults inside the Mazda were thrown from the vehicle and pronounced dead at the scene, according to authorities and sources. 

Later, a fifth occupant was discovered and also declared dead, police said. 

The Honda driver was taken to New York-Presbyterian Queens Hospital in stable condition, cops said. 

No arrests have been made, and the NYPD’s Collision Investigation Squad is probing the crash, authorities said.
