From the United States, more context regarding drunk driving.
A 2014 study from the National Highway Traffic Safety Administration updated statistics on the level of drunk driving recidivism by investigating data from 12 states and calculating the chance of being a repeat drunk driving offender depending on the type of charge: arrests, convictions and license suspensions.
In 1995, researchers found that one-third of all drivers convicted of DWI were repeat offenders. This study looked to re-explore and update repeat offender tallies.
In the United States, the amount of DWI arrests has dropped 25 percent since 1995, but drunk driving remains more common than other offenses, such as property crime, drug abuse violations, larceny-theft and assaults.
The researchers found, “although DWI arrests have decreased, DWI repeat offenders are still believed to make up a sizeable proportion of DWI arrests.”
Looking at data from 12 states, researchers calculated the amount of repeat offenders and compared them against other states. Each group was weighted against the type of drunk driving charges.
