1. Maryland treats a BAC of .08 or higher as driving under the influence. What does the manual say about impairment below that threshold?
Why: Although .08 is the legal DUI threshold, the manual is explicit that even one drink can impair judgment, physical coordination, and reaction time at a much lower BAC, increasing crash risk.
2. What happens if a Maryland driver under 21 is stopped by law enforcement and found to have been drinking any amount of alcohol?
Why: It's illegal for anyone under 21 to drink any alcohol at all in Maryland; if stopped after drinking, their license is suspended or revoked and they could face an added alcohol-restriction violation charge.
3. Maryland bans open containers of alcohol in a vehicle's passenger area. Which example does the manual give of something that counts as an open container?
Why: The manual specifically notes that a six-pack of alcohol with an open, empty, or missing bottle or can can be treated as an open container under Maryland law.
4. What can happen if a Maryland driver is convicted of drunk or drugged driving while a child was in the vehicle?
Why: If a driver is convicted of a drunk or drugged driving offense with a child in the vehicle, the judge can double both the fine and the jail time for that offense.
5. Under Maryland's implied consent rules, what can happen if an officer suspects a driver is impaired by drugs?
Why: If an officer has reason to believe a driver is impaired by drugs, alcohol, or a controlled substance, they may have a drug recognition expert request a blood test as part of Maryland's implied consent law.
6. What device must a Maryland driver install in their vehicle after being convicted of drinking and driving?
Why: A driver convicted of drinking and driving must install a breathalyzer-style ignition interlock device that prevents the vehicle from starting if it detects alcohol on the driver's breath.
