Nassau County police are urging drivers to slow down and use caution on Halloween.

Children chasing candy on Halloween face a high risk of being hit by vehicles, police said Monday in a news release.

Drivers should realize Halloween means increased pedestrian traffic and operate their vehicles accordingly, police said.

Motorists should be alert, slow down, come to a complete stop at all stop signs and proceed with extreme caution, police said.

According to the National Highway Traffic Safety Administration, the number of deaths among young pedestrians nationwide increases 4.5 times on Halloween night compared with the same time period all other nights of the year, police said.

Police also said children out on Halloween need to be careful. Crossing at corners, walking in groups and staying on sidewalks help reduce risks, police said.

Avoid dashing across the street in the middle of a block or cutting across yards or driveways.

Carrying a flashlight and wearing brightly colored costumes also help drivers more easily see pedestrians.

Also, trick-or-treaters should not wear masks that obstruct vision, and should avoid strangers and animals they don’t know.

Younger children should be accompanied by an adult, and older children not being escorted by an adult should carry a cellphone and some form of identification, police said.

Police said parents should have a detailed description of their children’s costumes and know where they will be on Halloween. Give children a specific time to be home and make sure they can reach you, police said.

Homeowners are urged to keep their yards clear, their dogs on leashes and provide well-lit walkways.

Nassau police said they will be intensifying patrols for Halloween, including using marked and unmarked vehicles to deter malicious property damage and other unlawful acts.
