It seems common sense that digital billboards are distracting, after all, that’s their job. But while the billboard industry tells advertisers “drivers won’t be able to avoid them,” they tell regulators that the signs don’t pose a safety hazard.
A recent study involving digital billboards and driver safety was conducted by the Swedish National Road and Transport Research Institute and funded by the Swedish Transport Administration, found that drivers looked at digital billboards significantly longer than they did at other signs on the same stretch of road, with the digital signs often taking a driver’s eyes off the road for more than two seconds.

July 2007 saw the release of two industry-sponsored studies which concluded that digital billboards are no more likely to case traffic accidents than conventional billboards. The billboard industry has since cited the studies numerous times as evidence that the proliferation of digital billboards poses no safety threat to the motoring public.
An objective, expert analysis of the studies has been prepared for the Maryland State Highway Administration by Jerry Wachtel, a highly regarded traffic safety expert. His report is extremely critical of the conclusions and methodology of both studies and effectively debunks them. Click here to download the report as a PDF document.
A study on the safety of digital billboards has been completed by the Federal Highway Administration, but its results have not been made public and we don’t know when or if we can expect them to be. But the following documents contain information that is important to the current debate. The titles of the documents below are links to their PDF versions.
April 2006, National Highway Traffic Safety Administration, U.S. Department of Transportation
A major study of driver inattention, primarily involving distractions inside the car, but finding that any distraction of over two seconds is a potential cause of crashes and near crashes.
