This FHWA study has been criticized on grounds that one of its co-directors has performed research for the Insurance Institute for Highway Safety ( IIHS ), a private corporation representing the auto insurance industry that profits significantly from insurance surcharges on drivers ticketed by red light cameras.

The FHWA study has also been criticized as containing critical methodological and analytical flaws and failing to explain an increase in fatalities associated with red light camera use :(…) the authors spotlight the statistical difficulties of including the cost of fatalities, while ignoring the practical implications of such events (…) assuming that each angle injury crash had a societal cost of $ 64, 468, when in fact the cost was $ 82, 816 before camera use and $ 100, 176 after camera use (…)

Nevertheless, the FHWA has concluded that the cameras yielded a positive overall cost benefit due to the reduction in more expensive right-angle injury collisions.
