GREENSBORO, N.C. - More than half of Americans carry around a smartphone. While you're out celebrating the New Year tonight, you might notice some people using smartphones to estimate their blood alcohol content.
Many of the apps ask you to enter your weight, the amount of time you have been drinking and how much beer, wine or liquor you drank. Then, the apps estimate whether you're going to have a blood alcohol content that makes it dangerous to drive.
Yes, they can give people a general idea about how much alcohol is dangerous. However, police and bartenders have serious concerns.
"A device on the phone, an app on the phone, I would not trust it to keep me out of jail, keep me from getting in a wreck and killing somebody. I just wouldn't trust that to keep me out of trouble," Greensboro Police Officer Douglas Campbell said.
Ham's Bartender Stephanie Bullins added, "There are apps literally for everything. But, I don' t think someone should rely on an app or their telephone to tell them if they are intoxicated or not. If you are drinking, I believe you should always have a safe way home."
Here's what affects your BAC (blood alcohol content):
* How much food is in your stomach
* How many drinks you have
* How fast you drink
Medications you're taking won't affect your BAC level, but they could make you feel more impaired and affect your ability to drive. Again, many of these apps don't take that into account.
Bartenders and police told WFMY News 2 if you're questioning whether you're ok to drive, you should not get behind the wheel. The safest and best app might just be one that finds you the nearest cab service.
