New York tour bus crash on interstate highway killed 5 passengers, authorities say.

"Avoid the NYS Thruway eastbound at all costs as a tour bus has rolled over near the Erie and Genesee County lines," Erie County executive Mark Poloncarz said on X. "This is a potential mass casualty incident," he said, adding that the county's emergency and security services are assisting.

On Jan. 5, 2024, a tour bus traveling through upstate New York from Montreal, Canada rolled over on Interstate 87 southbound in Lake George, resulting in the death of one passenger, a passenger with serious injuries and 10 passengers with non-life threatening injuries.
