BAC Test

Worcester Attorneys for BAC Test Challenges
Serving Worcester, Middlesex and Hampden Counties

If you were pulled over for OUI, a breathalyzer test was likely one of the tools police used to build their case. A BAC test lawyer at Rudolf, Griffis, Ruggieri & Murray can investigate whether that test followed the specific legal procedures Massachusetts requires. Blowing above the legal limit of .08% does not automatically mean a conviction, since flaws in how the test was given or maintained can undermine the result entirely.


Common Issues Affecting Breathalyzer Accuracy

Several factors can call a breathalyzer result into question:

  • Was the test given properly by a trained officer? Officers must be certified to administer the test correctly.
  • Was the device properly maintained and calibrated? Devices require regular maintenance and calibration to stay accurate.
  • Is there other evidence of intoxication? A high BAC reading alone isn’t always enough for a conviction if other evidence contradicts it.

Yes. Improper calibration, operator error, certain medical conditions, and even some diets can produce inaccurate readings. Challenging the reliability of the specific device and how it was administered is a common and often effective defense strategy.
