Defend Your Rights as a Driver When Alcohol or Controlled Substances Are Involved in an Arrest, the Oregon Prosecutors Will Take Your Criminal Matters Seriously

Breath Test Refusal

Medford DUII Defense Attorney with Trial Experience

While the majority of driving under the influence of intoxicants (DUII) offenses involve alcohol use, an increasing number of DUII cases involve drug crime related offenses, such as possession and illegal use of controlled substances. Use of controlled substances behind the wheel or driving under the influence of drug impairment is illegal in Oregon.

Law enforcement officials who assume that an individual is driving under the influence of an intoxicant will typically conduct field sobriety tests such as a breath test to determine the blood alcohol content (BAC) level of someone who is suspected to be driving under the influence.

While BAC can be used for individuals who are under the influence of alcohol, it is more challenging to determine - let alone prove - the amount of drugs or controlled substances in a person's system. If a law enforcement official cannot prove the amount of drugs that are present in your system, then it becomes increasingly challenging to determine the degree of impairment that the drug has on your ability to operate a motor vehicle.

If you were charged with a DUII even though your BAC was below 0.08%, or your DUII charge was based on alleged drug intoxication, you need to speak with a Medford DUII defense lawyer immediately.
