Got an email from Len, who wanted to chime in on the breathalyzer issue. - Tom.
If a person has consumed alcohol away from home, and he or she is concerned about being over the legal blood alcohol limit
, a personal breath testing device (PBT) might control their decision about driving home. Such a device can help avoid an accident, injuries, a night in jail or all three of them. PBTs are used by many police departments across the country for purposes of establishing probable cause to take a driver down to the station for certified breath testing. They're also available to the general public to help keep that from happening. For a charge, some bars even have their own stationary breath testing machines for use by their customers.
You Get What You Pay For
Any person who frequently consumes alcoholic beverages and drives might want to have a portable breath testing device. PBTs are hand-held devices that a person can use to measure their blood alcohol concentration anywhere that they might be. Some models even plug into smartphones with an app that performs all of the computations. They might be told right away if it's safe to get behind the wheel of a motor vehicle to drive home, or whether they should call Uber, Lyft
or a taxi service. What comes to issue is the consistency and reliability of these devices. There can be a differential of plus or minus 20 percent from one blow to another from the same person, especially on the least expensive models. That's a big variable when a determination must be made as to whether a person should even be thinking about driving.
PBT Reliability Issues
There's a reason why PBT testing isn't admissible for purposes of proving guilt or innocence in a DUI trial. Their results simply aren't reliable. Some units need to be periodically returned to the manufacturer for recalibration. Others simply deteriorate over time. Even the most expensive PBTs carry a disclaimer on the back of their packaging. Others are marked as being for personal or home use only. Remember the reason for that: PBT results are generally unreliable.

Trust Your Gut
It's more likely than not that if you have any amount of an alcoholic beverage on your breath, and you're the subject of a traffic stop, you're going to end up at the police station with a blow or no blow dilemma. Your PBT results are irrelevant. The decision on whether to blow is up to you, but remember, if you refuse that breath testing, and you're found guilty of DUI, the penalties are going to be even more severe.
