Long Island officials warned drivers ahead of what is known as one of the biggest bar nights of the year.

Thanksgiving Eve is one of the worst nights for drunk driving.

Nassau and Suffolk's DAs say anyone who drives under the influence of alcohol and drugs will face consequences.

"If you drink and drive, you will be arrested and you will be prosecuted," said Nassau District Attorney Anne Donnelly

Police say anyone heading out should plan a safe way of getting home ahead of time.

Nassau Police Commissioner Patrick Ryder says people should discuss a plan with friends, call an Uber, have a designated driver or walk home.

"But don't be one of those without a plan - because you will then meet our plan," Ryder said.

Nassau and Suffolk law enforcement officials say their departments will be out in full force to protect people on the highways.

Police are asking anyone on the roadway to call 911 if they see someone driving recklessly.
