The Methuen Police Department is cracking down on crosswalk violators. Using a $5,000 grant from the Massachusetts Executive Office of Public Safety and Security, officials have produced informational cards explaining crosswalk law and responsibilities when encountering bicyclists. The cards are being distributed throughout the city. Sting operations have also been run, in which police officers pose as pedestrians in a crosswalk; drivers who disregard them are then ticketed. During a recent one-day operation, dozens of drivers were cited at various intersections. Police Chief Joseph Solomon said the program aims to highlight pedestrian safety and the dangers of distracted driving.
