Gov. Chris Christie says all of the cameras have been certified.
Christie made the announcement Tuesday night on New Jersey 101.5's "Ask The Governor" program after receiving a text message from Transportation Commissioner Jim Simpson.
The state suspended the pilot program last month in all but four municipalities after saying yellow lights might not be timed according to standards.
Tickets were not issued at the intersections while officials reviewed the timing.
Motorists who paid fines from tickets at those intersections can seek to reopen their cases.
