Suffolk County police say cars began getting stuck on Friday afternoon because weather conditions have been so bad. Authorities say vehicles are backed up and can't pass one another, and mounds of snow from plows have made it difficult for them to exit the highway.
Police say disabled motorists remain on the road early Saturday, and officers are working to get them off the road and make sure they're safe.
The Long Island Expressway and Sunrise Highway are both shut down in Suffolk County except for emergency vehicles.
Authorities say no injuries have been reported.
