You can be arrested if a police officer had probable cause to believe you were under the influence of alcohol, chemical or controls substances to the extent your normal faculties were impaired. If the only information the officer had was your low breath result, you should not have been arrested unless the officer can point to other evidence of impairment by controlled substances or chemical substances. There are very few police officers who can do that, they are called Drug Recognition Experts or “DRE”. Unless you exhibited serious signs of impairment or urine test positive for drugs, a breath result that low will rarely if ever result in a conviction for DUI.
