Maryland driving laws
The rules your permit test asks about, in plain English. Each one is quoted from Maryland’s statutes or an official MVA page. Handbooks are often years out of date, so where the law has changed we follow the law.

- Alcohol and drugs (DUI)
- In Maryland a BAC of 0.08 or more is driving under the influence per se.

- When a school vehicle stops with its red lights flashing, traffic in both directions must stop at least 20 feet from it and wait until it moves or the red lights go off.
