Robert Poole evaluates a Texas Transportation Institute before-and-after analysis of accident rates on Texas freeways with HOV lanes.
"About 90% of all high-occupancy vehicle (HOV) lanes are separated from adjacent travel lanes only by what is called a "buffer"double white lines on the pavement. As a result, unless there is stringent enforcement (high fines and aggressive police monitoring), non-carpool drivers tend to dart in and out of the HOV lanes to bypass congestion in the regular lanes. And that leads to accidents."
