In Maryland, particularly in Maryland, breath tests are commonly administered during DWI stops to determine a driver’s level of intoxication. These tests include preliminary breath tests (PBTs) at the roadside and more sophisticated breathalyzer tests at police stations. While PBTs provide initial estimates and are not typically admissible in court, breathalyzer results are considered more reliable and can significantly influence the outcome of a DWI case. However, both types of tests have specific legal and procedural requirements that must be met to ensure their reliability and admissibility.
At Ryan Law LLC, we focus on the intricacies of both PBT and breathalyzer tests, ensuring that any test administered to our clients complies with the required standards. We scrutinize the conditions under which these tests were conducted, from the calibration of the devices to the training of the officers involved, to identify any potential grounds for challenging the results.
