A Department of Sanitation garbage truck struck and killed a woman Wednesday evening as she was crossing Bay Parkway in Brooklyn, according to the NYPD.

Siobhan Lynch, 30, of Brooklyn, was crossing the parkway at Cropsey Avenue around 6:35 p.m., 40 minutes after sunset, when the truck, heading east, turned right onto the parkway and hit her, police said.

Emergency services took Lynch to NYU Langone Hospital, where she was pronounced dead. The truck’s 41-year-old driver stayed at the scene and has not been arrested, police said. The NYPD’s Highway District Collision Investigation Squad is investigating.

“This is a terrible tragedy, and our thoughts are with the family of the victim,” Department of Sanitation spokesperson Joshua Goodman said in an email. “DSNY is assisting NYPD with their ongoing investigation.”

The crash comes just days before daylight saving time ends, meaning clocks will fall back and the sun will set an hour earlier.

The Mamdani administration launched its Dusk and Darkness campaign Thursday, a combination of education and traffic enforcement to help protect pedestrians and cyclists during fall and winter evenings. The city says traffic deaths rise to their highest levels during this time of year.

”As the sun sets earlier and daylight savings time ends, there's reduced visibility for drivers, pedestrians, cyclists, and everyone who shares our streets,” Transportation Commissioner Mike Flynn said at a news conference. “My message to all New Yorkers is simple: slow down, look for pedestrians and cyclists, and use caution when turning at intersections.”

As part of the campaign, the NYPD plans to target speeding, failure to yield and distracted driving during the evening commute.

Flynn said traffic deaths through September were at their second-lowest level since the city began tracking them more than a century ago, and pedestrian deaths were at a record low.
