FORT LEE - Drivers who don't stop for pedestrians in crosswalks should consider themselves warned.

Fort Lee police are going undercover to see if drivers along Hudson Terrace stop for a pedestrian crossing the street.

Officers say the operation is part of an effort to educate drivers about New Jersey's pedestrian crossing law.

The law says once a pedestrian steps into a crosswalk, traffic in both directions must stop. Drivers must remain stopped until the pedestrian reaches the other side of the road.

Det. Vincent Buda says the violations are a big problem in Fort Lee. More than a dozen people have been struck by cars, and one victim was killed.

During the two-day crackdown, police handed out more than 100 tickets. The fine for failing to stop for a pedestrian in a crosswalk is $230 and two points on your license.
