One reason for challenging a DUI breath test in Rochester is the improper administration of the test. For example, the police officer administering the test must first observe the driver suspected of driving under the influence for a full 15 minutes before administering the breath test.

The results of a DUI breath test could also be challenged if the machine used to administer the test was not properly calibrated at the time. Additionally, the law requires that breath test machines be tested once per week and additionally once per quarter. If the machine’s calibration is not tested, as necessary and adjusted as needed, or if the machine has not been otherwise maintained according to schedule, the results of any breath test could potentially be incorrect.

After stopping a driver for allegedly rolling through a stop sign, an officer determines that the driver appears to be impaired and administers a DUI breath test. If the driver fails the breath test, they could be charged with driving under the influence of alcohol.

A Rochester lawyer who understands how to challenge a DUI test based on a lack of probable cause could fight to disqualify improperly obtained evidence to help dismiss charges.
