In Indiana, it is illegal to drive with a blood alcohol concentration (BAC) level that is .08 percent or higher. Commercial vehicle drivers may not operate a commercial vehicle with a BAC of .04 or over. If you are under 21, you may not operate a vehicle with a BAC of .02 percent or higher.
A police officer may pull you over and then administer a breathalyzer test, or the officer may arrest you and then administers a blood or urine test. If the tests find you to have a BAC of at least .08 percent, or .02 percent if you’re under 21, you may face a charge of “per se” DUI.
If you are under the influence of drugs, you may also face an OWI charge; however, Indiana does not specify blood limits for these substances. An officer may use evidence of your intoxication, such as swerving while driving, as probable cause to arrest you and test your blood or urine for intoxicants.
There are ways to fight a blood alcohol concentration level test. A Lafayette IN DUI lawyer can challenge your BAC test and seek to have your charges reduced or dropped entirely. BAC chemical tests are notoriously inaccurate. It is worth having our Lafayette IN DUI lawyer review your case and determine if you can challenge your test results.
