After California banned the use of cell phones while driving in 2008, one might expect that the rate of accidents in the state would go down.
New research, however, shows that the laws did little to reduce accidents in the state.
The study, published in Transportation Research Part A: Policy and Practice analyzed the number of accidents in the six months before and after California's law went into effect.
Researchers found that the number of accidents in the state only dropped to 65.2 per day compared to 66.7 per day, a statistically slight decline.
"If [cell phone use is] really that dangerous, and if even just a fraction of people stopped using their phones, we would expect to find some decrease in accidents," study author Daniel Kaffine said. "But we didn't find any statistical evidence of a reduction."
Â The researchÂ mirrors other results -- the Highway Loss Data Institute studied insurance claims in 2009 and 2010 and found no link between cell phone bans and a decrease in accidents.
Thirteen states have hand-held cell phone bans, and 44 states outlaw texting while driving.
