Red Light Cameras By Stephen Bainbridge

News that Virginia has banned the use of red light cameras reminded me of the minor stir kicked up a couple of years ago when my friend and colleague Eugene Volokh surprised his fellow libertarians by defending their use (see his op-ed and blog post). In contrast, I hate the [email protected] things, but I figured they at least save lives and property. According to the report on Virginia’s action, however, they don’t:

Virginia’s decision was prompted in large measure by a state Department of Transporation study study showing an overall increase in injury accidents where red light cameras were used. Similar findings have appeared in studies from North Carolina; Ontario, Canada and Australia.

This seems counter-intuitive doesn’t it? After all, shouldn’t red light cameras reduce accidents by discouraging red light bandits? According to the linked studies, however, it turns out that any such effect is more than off-set by a dramatic increase in rear-end collisions. Apparently people approaching a camera-enforced intersection as the light changes tend to slam on their brakes to the surprise of the driver behind them.

The law of unintended consequences once again rears it ugly head and bites safety regulators in the @ss. (So to speak.)
