Our DWI defense lawyers in Shelby are used to answering questions about the legal limit in NC.
There’s a fair amount of incorrect information out there, especially when it comes to what is impaired driving and whether that’s the same thing as “drunk driving.”
Chances are you’ve seen public safety advertisements and campaigns with catchy phrases like “Drive High Get DUI” and “Drive Sober or Get Pulled Over.”
“While well-meaning, telling someone to drive ‘sober’ doesn’t really help people understand the NC DWI laws and what is and is not legal – David Teddy, DWI Defense Lawyer Shelby NC
What is the Legal Limit in North Carolina?
Clearly, part of the confusion is that we haven’t always focused on educating people on the impaired driving laws.
Not that long ago, .10 was the legal standard applied to Driving Under the Influence or “DUI” charges in North Carolina.
If you’ve taken an NCDMV written test in the recent past, chances are you studied-up on the “legal limit.”
You may remember something about .08 or higher.
Then again, you may also recall some types of licenses are subject to a 0.04 limit or restriction.
Other types of drivers, most notably younger, new drivers who may be referred to as “provisional drivers” or “provisional licensees” by defense lawyers, aren’t allowed to have any amount of alcohol in their system.
It’s all a bit discombobulating in that it’s quite common for people to refer to impaired driving as “drunk driving” and the “legal limit” as .08.
The “legal limit” in North Carolina is technically a number below .08.
For example, .079 is below .08 and therefore may technically be referred to as the “legal limit.”
Breath tests or blood tests indicating a .001 higher reading, making it .08 would be enough for a finder of fact (judge or jury as the case may be) to find the person accused of DWI guilty of driving while impaired.
What does BAC mean?
One of the more common terms DWI defense lawyers use, in explaining DWI charges to clients, is “BAC.”
That stands for Blood Alcohol Content.
It generally refers to the amount of alcohol in your bloodstream.
“We make sure clients understand the technical differences between results from say a ‘Breathalyzer’ and those obtained pursuant to a blood draw and possible Search Warrant – David Teddy, DWI Defense Lawyer Shelby NC
That in-and-of-itself is subject to some level of confusion, in that we (North Carolina) no longer use the Breathalyzer machine as an accepted type of scientific evidence in DWI trials.
Breath Alcohol test results would most accurately be referred to as BrAC.
Breath tests estimate the amount of ethyl alcohol (ethanol) in your bloodstream.
The resulting number from the “blow” is an extrapolated value that takes into consideration and assumes certain factors such as a standard breath-blood partition ratio, available TVA or Tidal Volume of Air, and correct alveolar sampling.
As such, BrAC is converted to BAC by the machine in calculating the reading after you blow.
Blood Alcohol Content, which is sometimes also referred to as Blood Alcohol Concentration, is the true BAC.
Is the Breathalyzer Admissible?
The Breathalyzer was a type of breath testing machine that hasn’t been used for decades.
Even so, people still regularly refer to all types of breath testing devices as “the breathalyzer.”
It was replaced by a breath sampling machine called an Intoxilyzer 5000.
That too has been updated under the NC DWI laws (the NC Administrative Code).
The most common machine used to test for impaired driving and BAC in North Carolina is referred to as the EC/IR II and it is manufactured by the Intoximeters Corporation.
People also regularly refer to the handheld PBT – Portable Breath Test as a “breathalyzer.”
As such, DWI defense lawyers are careful to explain the different types of devices and readings.
“We think it’s a good idea to properly describe the devices and readings to clients. It can be very easy to confuse – David Teddy, DWI Defense Attorney
