A study in Ontario, Canada is the fourth major study to conclude that, far from reducing accidents, red-light cameras are actually harmful.
The 2003 study, covering Toronto, Hamilton, Ottawa, Halton, Peel and Waterloo, found that overall property damage accidents increased 18.9%, rear-end property damage accidents increased by 49%, and fatal and injury rear-end collisions increased by 5%, after red-light cameras were deployed. Other studies have previously found adverse results in Virginia, North Carolina, and Australia.
