In Maryland, a lack of knowledge of the driving laws is considered no excuse for any violation. This principle is based on the idea that every driver is responsible for understanding and adhering to the laws governing road use. It underscores the expectation that individuals should familiarize themselves with traffic regulations before operating a vehicle.

Legal accountability in driving situations requires that all drivers possess a fundamental understanding of applicable laws, regardless of whether they claim ignorance. Courts uphold this standard to ensure safety and order on the roads, implying that just because a driver doesn’t know the laws does not absolve them from consequences if they violate them. This doctrine reflects the broader legal principle that ignorance of the law is not a defense in any legal matter, including traffic violations.
