Most people commonly use the terms interchangeably, assuming a drunk driving charge is a drunk driving charge no matter what specific label it gets called by police or prosecutors. Maryland law disagrees entirely, treating these as two genuinely separate offenses with different thresholds, different penalties, and different defense strategies depending on which one actually applies.
Two Separate Offenses Under One Statute
Maryland law creates two distinct impaired driving charges under Transportation Article Section 21-902, and which one actually applies depends heavily on the specific evidence gathered during the traffic stop.
Why the Charge Involved Changes the Defense
A Maryland DWI attorney has to identify early exactly which charge, or charges, a client is actually facing, since the strategy for defending each one looks meaningfully different from the outset.
Where the Line Between the Two Actually Sits
The more serious charge applies once blood alcohol concentration reaches 0.08 percent, at which point the law establishes what is called a per se presumption of impairment. That means prosecutors do not need additional evidence beyond the chemical test result to move forward with the higher charge and secure a conviction. The lesser offense covers blood alcohol readings between 0.07 and just under 0.08 percent, or situations where an officer observed genuine impairment without the reading alone establishing it automatically under the statute, meaning the arresting officer’s own testimony and field notes take on far greater importance in these particular cases than they otherwise would.
Why This Distinction Actually Matters
The two charges carry meaningfully different, real consequences for anyone ultimately convicted at the end of a case. A first offense at the higher level can bring up to a year in jail, a larger fine, and more points against a license, while the lesser charge carries a shorter potential jail term, a smaller fine, and fewer points assessed against the driving record. Prosecutors can sometimes bring both charges from a single traffic stop, but a defendant can only ultimately be convicted of one of the two, with the lesser charge folding into the more serious one if that particular conviction results from the case at trial.
What Factors Determine Which Charge Applies
Several pieces of evidence typically shape which specific charge a prosecutor ultimately decides to pursue in a given case. Common factors include:
- The exact blood alcohol concentration shown on the chemical test result itself
- Field sobriety test performance observed and documented by the arresting officer
- Whether a breath test was refused, which carries its own separate legal consequences
- Any additional evidence of impaired driving behavior noted by police before the stop
A skilled, experienced defense often focuses on whichever of these factors is weakest in the state’s overall case, since undermining one single piece of evidence can shift how the entire charge gets evaluated by a judge or jury at trial.
Why Reducing the Higher Charge Matters
One of the more common defense strategies in Maryland involves negotiating a higher charge down to the lesser one, given how significantly the penalties differ between the two options. A Maryland DWI attorney evaluates whether the evidence supporting the more serious charge is actually as strong as it initially appears, since chemical test procedures and field sobriety evaluations are not always conducted correctly by the arresting officer in the first place.
Getting the Right Defense for Your Charge
Understanding which specific charge you are actually facing, and why, shapes every single decision that follows in a case. The Law Firm of Frederick J. Brynn, P.C. has defended clients against impaired driving charges throughout Maryland for years, building strong defenses around the specific evidence each individual case actually involves rather than relying on a generic strategy. If you are facing either one of these two charges, reach out so your case can be evaluated carefully based on the facts that actually apply to your specific situation.
