Breathalyzer Test

Lawyer

Gregory Chancy

Synopsis

Breathalyzer Testing Under Georgia Law

  • A Breathalyzer test measures the concentration of alcohol in a driver’s breath to estimate blood alcohol content (BAC).

  • Georgia law enforces an “implied consent” rule, by driving, you agree to chemical testing if lawfully arrested for DUI.

  • Refusal to take the test can lead to license suspension and be used as evidence of impairment in court.

  • Breath tests are commonly administered using Intoxilyzer 9000 devices approved by the Georgia Bureau of Investigation.

Legal Limits and Test Procedure

  • For drivers 21 and older, the legal BAC limit is 0.08%.

  • For commercial drivers, it’s 0.04%, and for underage drivers, it’s 0.02%.

  • Police must read the Implied Consent Notice before administering the test.

  • Drivers have the right to request an independent chemical test after taking the state-administered test.

Challenging Breathalyzer Results

  • Improper calibration or machine malfunction can lead to false readings.

  • Operator error, if the officer wasn’t properly certified, results may be excluded.

  • Medical conditions (e.g., GERD, diabetes) or residual mouth alcohol can distort readings.

  • Violation of procedure, like failing to observe a 20-minute waiting period before testing, can justify suppression of results.

  • Defense attorneys often file motions to suppress to challenge the validity of the Breathalyzer evidence.

Refusal and License Consequences

  • Refusing the Breathalyzer test triggers an automatic one-year license suspension under the Administrative License Suspension (ALS) process.

  • A refusal can also be used as circumstantial evidence of impairment in a DUI trial.

  • However, the defense can argue that the refusal was based on confusion or unlawful arrest procedures.

Why This Matters

  • Breathalyzer results are often the core evidence in Georgia DUI cases.

  • Challenging the accuracy or legality of the test can lead to reduced charges or case dismissal.

  • Understanding your rights during a DUI stop helps protect your license, record, and freedom.

  • Experienced DUI defense attorneys know how to question every step, from arrest to equipment maintenance.
