Apps aimed at keeping drunken drivers off the road

'Appy holidays for drivers

'Tis the season for festive gatherings—and probably indulging in a second glass of wine.

First, and most emphatically, no one should drink and drive—not during the holiday season, not ever. According to the Centers for Disease Control, alcohol-related car accidents kill about 10,000 people a year, or one death about every 48 minutes.

If you decide to ignore those statistics and try to get behind the wheel of a car, you might consider downloading these apps.

BreathalEyes, Intoxicheck and DrinkTracker are a few that can help show people they've had too much cheer.

Intoxicheck, a self-administered blood alcohol content (BAC) test with challenges, helps users get a clearer idea of their impairment level. It takes about 10 to 15 minutes to complete, however.

DrinkTracker, a personal breathalyzer simulator and BAC calculator, doesn't require much time. Just enter a few details about yourself—including weight, sex and how much you've imbibed—and it will let you know your ability (or inability) to drive.

More of a party trick more than anything else, BreathalEyes videotapes a user's eyeball movement to determine alcohol intake.

Partiers should also be aware of Uber and Lyft. The former connects a user to a driver at a tap of a button, while the latter facilitates on-demand, peer-to-peer ride-sharing.

In addition, StearClear can get an on-demand designated driver for those who have had too much to drink but want to get their vehicle home. StearClear charges a $20 flat-rate pickup fee, plus $2 per mile.
