Maryland DUI Laws

In the state of Maryland, there are four different types of impaired driving-related offenses:

  • Driving while under the influence of alcohol. Section 21-902(a).
  • Driving while impaired by alcohol. Section 21-902(b).
  • Driving while impaired by drugs or drugs and alcohol. Section 21-902(c).
  • Driving while impaired by controlled dangerous substance. Section 21-902(d).

Standards, Presumptions, Definitions: Generally

Furthermore, the term “drugs” and “controlled dangerous substances” are distinct, with the latter referring to Schedule I through Schedule V controlled substances. Section 5-101(f). Thus, “drugs” refers to substances that are not included in the federal DEA and FDA’s controlled substance Schedules I through V.

  • In the state of Maryland, it is considered to be a Per Se violation of driving under the influence of alcohol if the driver has a Blood Alcohol Content (BAC) of 0.08 or higher. Section 2-501.
  • If a driver’s BAC is 0.05 or less, then the presumption will be that the driver is neither under the influence of alcohol nor impaired by alcohol. Section 10-307(3)(b).
  • If a driver’s BAC is higher than 0.05 but less than 0.07, then there will be no presumption based on the driver’s BAC (although the BAC may be used along with other competent evidence to come to a conclusion as to the driver’s state of impairment or lack thereof). Section 10-307(3)(c).
  • If a driver’s BAC is 0.07 or higher but less than 0.08, then it will be presumed that the driver was impaired by alcohol. Section 10-307(3)(d).
  • If a driver’s BAC is 0.02 or higher, then the BAC will be prima facie evidence that the driver was operating a motor vehicle with alcohol in his or her system. Section 10-307(e). This is significant because for drivers with an alcohol restriction, (see Section 16-113(b)(2)) such as drivers under the age of 21, having a BAC means violating that restriction. Section 10-307(f).

A refusal to submit to testing has a penalty of an automatic 180-day driver’s license suspension the first time a person refuses.
