Commercial Carrier Safety Inspection Unit personnel are responsible for implementation and enforcement of the federal safety regulations governing commercial vehicle drivers and the related equipment which they operate. CCSIU is also responsible for the enforcement of commercial vehicle state size and weight laws at both five fixed scale installations, strategically-placed throughout New Jersey, as well as two roving weight teams. Having adopted the Federal Motor Carrier Safety Regulations, the Division has assigned troopers with specialized training and certifications to this unit to conduct roadside safety inspections and post-crash investigations on a myriad of commercial vehicle types traversing the State’s highways and byways.
