Which item is NOT typically checked during a Maryland safety inspection?

During a Maryland safety inspection, the focus is primarily on the vehicle's safety features and the overall condition of components that directly impact its ability to operate safely on the road. Items such as brake efficiency, exterior lights, and tire tread depth are fundamental checks because they are crucial for ensuring the vehicle can stop properly, be visible to other drivers, and maintain adequate traction on the road.

Engine performance indicators, while important for the overall operation of the vehicle, are not typically included in the basic safety inspection checklist. The inspection is more concerned with the physical safety equipment rather than the performance metrics of the engine itself. This allows inspectors to focus their attention on aspects that directly affect the safety of the passing vehicle without getting into performance-related issues that do not compromise safety at the moment.
