Don't drink and drive - PERIOD. I believe most people don't, but there are those situations where you go out for a drink or two, maybe have something with dinner, feel completely fine and then drive home. If your judgement has already been impaired by alcohol, of any limit, then why do you trust it to decide if you should get behind the wheel? Stay on the safe side, for everyone's sake, and get a second opinion by blowing into one of these cool new BACtrack SingleShot - Disposable Breath Alcohol Testers.
Unlike those large and pricey electronic breathalyzers, these inexpensive, single-use breath alcohol testers don't require batteries, maintenance, recalibration or training. Just squeeze the center of the tube to activate the test, blow through it for 12 seconds and if the crystals change color from yellow to blue-green, then your blood alcohol level is at or above the limit. The testers are clinically proven to be over 99% accurate with rapid results, have been cleared by the U.S. Food & Drug Administration and Department of Transportation as an Alcohol Screening Device and are available in 0.02% (zero-tolerance), 0.05%, and 0.08% (legal driving limit) BAC thresholds. It's simple to use, easy to read the results and small enough to fit in any purse or pocket. Although these are great to have, please remember to just drink responsibly in the first place.
