Alcohol and drugs

Note: Alcohol/drugs as a contributing factor

From 2016, alcohol information from crash reports is not comparable with earlier years. Prior to 2016, alcohol/drugs is listed as a factor when a driver’s blood or breath alcohol level is above the legal limit, if drugs are proved to be in the driver’s blood, or when the attending officer suspects that alcohol/drug consumption contributed to the crash. From 2016 officer suspicion is not included.
