BERGENFIELD, N.J. — Just in time for Yom Tov, Bergenfield police are putting undercover officers into the crosswalks.

The department announced Thursday that officers will pose as pedestrians at several locations throughout the borough over the next several weeks, watching for drivers who fail to stop.

The timing comes as the Jewish holidays begin, when pedestrian traffic can increase in parts of Bergenfield as families walk to and from shuls, homes and holiday gatherings.

The Pedestrian Crosswalk Decoy operations are being conducted in cooperation with the New Jersey Division of Highway Traffic Safety.

Here’s how it works: Officers in civilian clothes will pose as pedestrians crossing the street while other officers watch nearby. Drivers who fail to stop for pedestrians or violate other laws can be stopped by police.

Under New Jersey law, drivers must stop and remain stopped for a pedestrian crossing within a marked crosswalk.

That makes the crackdown especially relevant during a stretch of the year when many Bergenfield residents may be out walking for the holidays.

Police say the operation is aimed at both enforcement and education, with reducing pedestrian injuries and fatalities among the department’s goals.

The department is also reminding drivers that yielding to pedestrians when turning at intersections is required by law.

“Remember, stopping for people in marked crosswalks and yielding when turning at intersections is the law!” the department said.

The operations will continue at several locations throughout Bergenfield during the coming weeks.

With Yom Tov bringing more people onto the streets, the message for drivers is simple: If someone is crossing, stop.
