A drunk driver caused a chain reaction crash on the Long Island Expressway that involved five vehicles and seriously hurt two people, police said Saturday.
Charles Healy, 56, of West Islip, was charged with driving while ability impaired by the combination of drugs and alcohol, Suffolk County police said.
He's accused of hitting a Mazda rental car just before midnight Friday on the Long Island Expressway between exits 56 and 57 in Hauppauge.
The Mazda then hit a Subaru, which struck a Jeep, which crashed into another Subaru.
Two passengers in the Mazda -- a husband and wife from Ontario, Canada -- were taken to Stony Brook University Hospital for serious, but not life-threatening, injuries.
Another driver and Healy were both treated for minor injuries.
It wasn't clear whether Healy had an attorney.
The Long Island Expressway was closed for hours overnight due to the crash.
