OLD BROOKVILLE - Many traffic lights are still without power after Tropical Storm Irene, and drivers say it is making some local roads very dangerous.

Nassau police say they have officers directing traffic at large intersections, but they are asking drivers to be courteous and use caution when maneuvering through roads that have disabled traffic lights.

"Pretend there's a stop sign at every intersection," says Detective Lt. Kevin Smith, of the Nassau County Police Department.

News 12 Long Island did find Old Brookville police officers directing traffic at the busy intersection of Route 107 and Wheatley Road, but there were no cops at a traffic light near Jericho High School.

The Long Island Power Authority says it's working with all of the towns to identify critical spots where traffic lights have no power and send crews to bring them back online.
