DUI Breathalyzer Tests

Posted by Sean Quinlan | Dec 11, 2023 | 0 Comments

A DUI breathalyzer test is a chemical test used to measure the blood alcohol content (BAC) of a driver. Breathalyzer tests are commonly used by law enforcement officers to determine if a driver is under the influence of alcohol.

If you are pulled over and suspected of driving under the influence, you may be asked to take a breathalyzer test. You are not legally required to take a breathalyzer test, but if you refuse, you may still be arrested and charged with a DUI.

If you take a breathalyzer test and your BAC is above the legal limit, you will likely be arrested for DUI. The legal BAC limit for drivers over the age of 21 in Pennsylvania is 0.08%. However, the BAC limits for drivers under the age of 21 is lower that .08.

If you are convicted of a DUI, you could face serious penalties, including fines, jail time, and a suspended license.

How does a breathalyzer test work?

A breathalyzer test works by measuring the amount of alcohol in a person's breath. When a person drinks alcohol, some of the alcohol is absorbed into the bloodstream. The alcohol then travels to the lungs, where it is released into the breath.

A breathalyzer test measures the amount of alcohol in the breath and converts that amount into a BAC. The BAC is a measure of the percentage of alcohol in the blood.

What are the different types of breathalyzer tests?

There are two main types of breathalyzer tests: roadside breathalyzer tests and evidential breathalyzer tests.

Roadside breathalyzer tests are handheld devices that are used by law enforcement officers to quickly screen drivers for alcohol intoxication. Roadside breathalyzer tests are not as accurate as evidential breathalyzer tests, but they can give police officers a reason to arrest a driver for DUI.

Evidential breathalyzer tests are more accurate than roadside breathalyzer tests. Evidential breathalyzer tests are typically used at police stations and are used to obtain evidence for DUI prosecution.

How accurate are breathalyzer tests?

Breathalyzer tests are generally accurate, but there are some factors that can affect the accuracy of the test, such as:

  • The type of breathalyzer test used
  • The calibration of the breathalyzer test
  • The operator of the breathalyzer test
  • The subject's breath temperature
  • The subject's use of medications

What are some common DUI breathalyzer test defenses?

There are a number of common DUI breathalyzer test defenses, such as:

  • The breathalyzer test was not properly calibrated
  • The breathalyzer test was not properly operated
  • The subject's breath temperature was too high or too low
  • The subject was using medications that can interfere with the accuracy of the breathalyzer test
  • The subject had recently eaten or drunk something that can interfere with the accuracy of the breathalyzer test

If you have been arrested for a DUI and you believe that the breathalyzer test results are inaccurate, you should contact a DUI attorney to discuss your case.

What are the consequences of a DUI conviction?

The consequences of a DUI conviction can be severe, depending on the state in which you are convicted. Common DUI penalties include:

  • Fines
  • Jail time
  • A suspended license
  • Ignition interlock device requirement
  • Increased insurance rates
  • Difficulty finding employment

If you have been arrested for a DUI, it is important to contact a DUI attorney to discuss your case and your legal options. A DUI attorney can help you build a strong defense and fight for the best possible outcome in your case.

How can I avoid a DUI?

The best way to avoid a DUI is to not drink and drive. If you are going to be drinking, make sure to have a designated driver or take a taxi or ride-sharing service home.

If you are pulled over for suspicion of DUI, be polite and cooperative with the police officer. Do not argue with the officer or refuse to take a breathalyzer test. If you are arrested for DUI, contact a DUI attorney immediately.

Conclusion

A DUI breathalyzer test is a serious matter. If you are arrested for a DUI, you could face serious penalties. If you believe that the breathalyzer test results are inaccurate, you should contact a DUI attorney to discuss your case.
