What is required before taking a driving test in Maryland?

Before taking a driving test in Maryland, it is essential that the vehicle is in safe operating condition. This requirement ensures that the vehicle can be driven safely and that the examiner can evaluate your driving skills effectively without any mechanical issues that could compromise safety. Having a vehicle that meets safety standards is crucial not just for passing the test, but also for the overall safety of the driver and others on the road.

While the other options mention important vehicle conditions and regulations, they do not encompass the broader requirement of ensuring the vehicle's general safe operational state. For instance, even if headlights are functioning or passengers are buckled, these alone do not guarantee that the vehicle meets comprehensive safety criteria needed for the driving test.
