What New Jersey's rule actually requires.
Abigail's Law established a front-and-rear detection requirement for covered New Jersey school buses. The current Department of Education rule defines a sensor system broadly enough to include radar, video, sound, infrared or other qualifying technology.
Covered manufacture dateThe current rule applies to school buses manufactured after April 16, 2018.
Front and rear detectionThe required detection area varies based on whether the bus is at or below 10,000 pounds GVWR or over 10,000 pounds GVWR.
Driver notificationThe system must provide the specified driver alert signals or a video monitor relaying the designated detection area.
Correct activationThe rear system operates with reverse gear; the front system activates under the passenger-door conditions described by the rule.
Important: “Abigail's Law camera” is common industry shorthand, but the legal requirement concerns the complete sensor system. Compatibility, detection coverage, alerts, activation behavior and installation all matter.
