The first data from breathalyzer selfies – measurements of blood-alcohol content by a new smartphone app – show that users drank the most on the weekend of the summer solstice, the longest day of the year.
San Francisco-based breathalyzer manufacturer BACtrack reported on Wednesday that the highest average blood-alcohol content (BAC) from April 2013 to April 2014 was registered on Saturday, June 22, at 0.115 percent. The legal definition for drunk driving is 0.08 percent.
The data shed light on drinking patterns, which can guide highway patrols and others determining when to focus drunk-driving enforcement.
But the primary purpose of the $149.99 BACtrack Mobile, which consists of a breathalyzer that sends readings via Bluetooth to a smartphone and was introduced in 2013, is to raise people’s awareness of how drinking affects their BAC and therefore causes impairment, said BACtrack founder and Chief Executive Officer Keith Nothacker.
