DELRAY BEACH, Fla. - The tragic, but realistic side of New Year's Eve is the increased danger of drunk drivers on our roadways. Several mobile phone apps claims to be able to help you decide if you should get behind the wheel.
Former Boca Raton Police Chief Andrew Scott says they can't be trusted.
"It's a gimmick, a gimmick that people but and think they're safe when indeed they're not," said Scott.
We tested one app which scans your eyes for impairment. It was hard to hold still to get it to work.
It then reported Scott had a blood alcohol content of .16 and then .02.
"I think we've just proven this is useless," said Scott.
"Word to the wise, for entertainment purposes only," said Diego Asencio, a volunteer with Mothers Against Drunk Driving.
He urges drivers to stay sober, there's no reason to put your trust in a mobile app.
"Anyone that's been drinking how do we know they'll administer the test correctly? And can you rely on the test? There are disclaimers all over these," said Asencio.
"If anyone thinks they're immune to this and they drink tonight, they could be on the news tomorrow morning as a result of drinking and driving and getting into a crash," said Scott.
