During a traffic stop, officers who suspect a driver may be driving under the influence of alcohol often administer a preliminary breath test (PBT), also known as a ‘breathalyzer.’ Although the test is well-known publicly, it is less known that, according to Maryland law, drivers may refuse the roadside breath test. While drivers may refuse the PBT, they will subsequently be taken to the police station to submit an official breath test, which is admissible as evidence in court. Drivers may believe that complying with every request made by an officer, such as the PBT and other field sobriety tests, will help their situation, however, submitting to unrequired roadside sobriety tests may actually do the opposite for their defense.
