For those headed out of town for spring break, whether it be to a sunny beach or a snowy ski slope, your vacation can create a lifetime of fond memories or, with one mistake, a lifetime of regret. Here are a couple of spring break apps to help you avoid that lifetime of regret.

A lot of students on spring break give in to the urge to drink and the lack of judgment that comes with alcohol use can lead to trouble. Police in spring break locales are beefing up their DUI patrols and are on the lookout for any driver that might show signs of being under the influence of alcohol. It’s such a big problem in spring break cities that the local police have no tolerance for driving under the influence and are very unforgiving.

One way to stay out of trouble is to decide on a plan before you go out to drink. If you decide beforehand that you’ll use a designated driver or call a cab to get home, chances are that you’ll stick with that decision but, if you wait until after you’ve been drinking and your judgment is affected, you may not make such smart choices. If you feel you must drink, here are a couple of spring break apps that, hopefully, will keep you out of trouble.

ENDUI (as in End DUI) is an app that warns you if you’ve had too much to drink. The user plugs in their sex, height, and weight and then, by telling it how many drinks have been consumed, it calculates your approximate Blood Alcohol Content (BAC). The app also has games that can test your reaction time. If you decide, before you go out, to limit your drinking, this can be a good tool to warn you when you’ve reached your limit. However, the app only gives an approximate BAC and can’t be used to determine your actual BAC. One drink, such as certain cocktails can have several shots and have up to four times the alcohol content of a typical drink. Only a breathalyzer or blood test can give an accurate BAC reading.

Another app called “SaferRide”, created by the National Highway Transportation Safety Administration (NHTSA), doesn’t try to determine your BAC but, instead, can locate and call a local taxi service for anyone who needs a ride home. It can also hold a list of designated drivers that the user pre-programs into the app. This app is ideal for those on vacation in an unfamiliar city.

Both of these handy spring break apps are free and available for download:

ENDUI –  Apple iOS or Android.

SaferRide – Android, or Apple iOS.

Remember that buzzed driving is impaired driving. Make your spring break a fond memory and not a regret.
