A state study finds intersections with red-light cameras in New Jersey are seeing fewer serious right-angle crashes, but more drivers rear-ending other cars.
The Transportation Department study also shows that with time, drivers get used to cameras and the number of tickets drops significantly.
In the two Newark intersections that had cameras for two years, citations went down by 85 percent.
The study looked at data from two dozen intersections statewide where cameras had been in place at least one year by May 1.
The total number of crashes at intersections with the cameras was up slightly in the first year. The number of rear-end collisions increased 20 percent. The costs associated with the crashes rose by more than $1.1 million.
The state says more study is needed.
