Smartphone Breathalyzer Survey Ends; Here’s What CDOT Discovered

By October 17, 2016Thomas Law Firm

Not long ago, we blogged about a study conducted by the Colorado Department of Transportation (CDOT) and BACtrack, a company that makes breathalyzers for smartphones. The study involved giving free breathalyzers to random participants throughout Denver and asking the recipients to report their experiences with the breathalyzers to CDOT. Reducing drunk driving was the goal of the study, which recently concluded. Here’s what CDOT has to say about the results.

  • More than 80 percent of participants said that they thought having a personal breathalyzer made them much less likely to be arrested for DUI.
  • A whopping 82 percent of participants believed that people who drink regularly would benefit from a personal breathalyzer.
  • From 4,823 blood alcohol concentration readings received by CDOT, the average BAC was 0.87 – just over the legal limit of 0.08 percent.
  • While the vast majority of the participants were aware of Colorado’s 0.08 BAC limit (92 percent), just under half were aware that the limit for the lesser charge of driving while ability impaired (DWAI) is 0.05.
  • Over 90 percent of participants believed they had ridden in a car with a driver who was too drunk to legally drive.
  • As one might expect, most of the readings came in on Friday and Saturday nights. While Sundays received around half as many readings as Fridays and Saturdays, Sundays had the highest average BAC rating of any day of the week at 0.101 percent.

While smartphone breathalyzers have proven a powerful awareness and deterrent tool for drunk driving, CDOT still recommends that drinkers plan ahead for safe rides home, instead of relying on the breathalyzer to prevent DUI.
