In Ohio, you can be charged with an additional offense of operating a vehicle with a prohibited concentration of alcohol and/or drugs in your system. Typically the substances which may be tested include blood, breath or urine. Ohio further distinguishes between a high concentration (or Tier) offense and a low concentration (Tier) offense. A low tier offense is defined as any blood or breath test with the result of .08% or higher but less than .17%. A low tier urine test as is defined as a result of at least .11 grams but less than .238 g. A high tier test is anything above a .17% for a breath or blood test, and in a urine test, a high test is defined as anything .238 g or above.
REFUSAL OF A CHEMICAL TEST

Two-year suspension with optional limited driving privileges after 90 days.
