DUI and DWI: What Is the Difference?

In Texas, you will likely see the terms DWI (driving while intoxicated) and DUI (driving under the influence) used interchangeably. However, it's important to understand that these are two distinct violations. The primary difference is the age of the accused.

DWI applies to adults who either have a blood alcohol content of 0.08% or greater, or whose use of alcohol is determined to be affecting their driving. You don't necessarily have to have a BAC higher than 0.08% to be charged with DWI.

DUI—or, as it is officially noted, DUIA (driving under the influence of alcohol)—pertains to people under the age of 21, who are prohibited in Texas from having any amount of alcohol in their systems when driving. Penalties for a DUIA conviction can include a 60-day license suspension, $500 in fines, and an alcohol education course. However, if the accused underage driver has a BAC of more than 0.08%, they can be charged with DWI. 

If you or a loved one face charges of DWI or DUI in or near Round Rock, TX, Jason Trumpler is a lawyer who can provide the compassionate legal counsel and aggressive DWI defense necessary to keep both adults and minors from being subjected to harsh legal penalties they don't deserve.

DUI and DWI Defense Strategies

Being charged with DWI or DUI does not mean a conviction is inevitable. Law enforcement personnel are trained to identify drivers who may possibly be operating their vehicles under the influence, but the truth is that this protocol is not perfect. Any missteps on the part of law enforcement can result in wrongful charges and violated civil rights. Jason Trumpler is a DWI lawyer serving Round Rock, TX, who excels at identifying misconduct in these cases in order to help clients avoid unjust penalties. Let's take a look at examples of misconduct that could lead to dropped or reduced DUI or DWI charges:

Lack of Probable Cause

Law enforcement personnel must have reasonable suspicion (such as erratic driving) to perform a traffic stop. Before they can make an arrest, they must have probable cause, or evidence that could reasonably indicate a crime has been committed. This could be the smell of alcohol on the driver's breath, open alcohol containers in the vehicle, or having red, glassy eyes. As your lawyer, Jason Trumpler will analyze your case to determine whether there truly was probable cause for your arrest.

Faulty Testing 

Breathalyzer tests are not foolproof—incorrect calibration is just one reason why these devices can return a false positive. Field sobriety tests are known to fall significantly short of 100% accuracy; people can fail them simply because they feel anxious. Blood tests can be mishandled, mislabeled, or contaminated, producing inaccurate results. An attorney like Jason Trumpler, who has handled many DWI cases, can identify circumstances that could call the accuracy of these tests into question.

Your best bet for an apt defense is to enlist the help of a lawyer. Call now to arrange to speak to an attorney with a track record of success on behalf of DWI clients.
