Study: Texting Bans Don’t Reduce Crashes; May Actually Increase Them

From the Highway Loss Data Institute, Sept. 29, 2010:

ARLINGTON, VA — It’s illegal to text while driving in most US states. Yet a new study by researchers at the Highway Loss Data Institute (HLDI) finds no reductions in crashes after laws take effect that ban texting by all drivers. In fact, such bans are associated with a slight increase in the frequency of insurance claims filed under collision coverage for damage to vehicles in crashes. This finding is based on comparisons of claims in 4 states before and after texting ban, compared with patterns of claims in nearby states.

The new findings, released today at the annual meeting of the Governors Highway Safety Association, are consistent with those of a previous HLDI study, which found that banning hand-held phone use while driving doesn’t cut crashes. HLDI is an affiliate of the Insurance Institute for Highway Safety.

HLDI researchers calculated rates of collision claims for vehicles up to 9 years old during the months immediately before and after driver texting was banned in California (January 2009), Louisiana (July 2008), Minnesota (August 2008), and Washington (January 2008). Comparable data were collected in nearby states where texting laws weren’t substantially changed during the time span of the study. This controlled for possible changes in collision claim rates unrelated to the bans — changes in the number of miles driven due to the economy, seasonal changes in driving patterns, etc.

“Texting bans haven’t reduced crashes at all. In a perverse twist, crashes increased in 3 of the 4 states we studied after bans were enacted. It’s an indication that texting bans might even increase the risk of texting for drivers who continue to do so despite the laws,” says Adrian Lund, president of both HLDI and the Insurance Institute for Highway Safety.

HLDI’s new findings about texting, together with the organization’s previous finding that hand-held phone bans didn’t reduce crashes, “call into question the way policymakers are trying to address the problem of distracted driving crashes,” Lund adds.

“They’re focusing on a single manifestation of distracted driving and banning it. This ignores the endless sources of distraction and relies on banning one source or another to solve the whole problem.”
