Cellphone bans don’t reduce accidents, research finds

165238909

Common sense says that talking on a cellphone while driving is not a particularly safe thing to do. But recent studies have found banning cellphone use while behind the wheel is not leading to a decrease in accidents.

The results are somewhat surprising and have left researchers and regulators scratching their heads, especially given that 13 states, the District of Columbia and several US territories have hand-held cellphone bans. Additionally, 44 states specifically outlaw texting while driving, according to the Governors Highway Safety Association.

The most recent study, published this summer in the journal Transportation Research Part A: Policy and Practice, analyzed California’s cellphone ban for drivers in 2008. Researchers found the number of accidents only dropped from 66.7 per day to 65.2 per day statewide, a statistically minor decline. The results were mirrored in many of the state’s major cities, including San Francisco, though Los Angeles did experience a slight decrease in accidents. Researchers looked at the six-month periods before and after the ban went into place on July 1, 2008.

“We went in there expecting to see something,” Daniel Kaffine, one of the study’s authors, told Autoblog. “[But] it was pretty clear to us that there was no compelling evidence of a decrease in accidents.”

Though offsetting for safety advocates, Kaffine’s research is in line with other findings. The Highway Loss Data Institute, the research arm of the Insurance Institute for Highway Safety, studied insurance claims rates in 2009 and 2010 studies, and found no link that bans helped decrease crashes.
