Are aftermarket modifications allowed under the Maryland State Inspection regulations?

Aftermarket modifications are indeed permitted under Maryland State Inspection regulations, provided they comply with state safety and emissions standards. This means that while vehicle owners have the flexibility to customize their vehicles, any changes made must not compromise the safety features or violate emissions regulations established by the state.

For instance, if an aftermarket exhaust system is installed, it must meet specific noise levels and emissions criteria. Similarly, modifications that affect the vehicle's lighting, brakes, or suspension systems must ensure that the vehicle remains safe to operate on public roads.

In contrast, the other options suggest complete prohibitions or overly restrictive guidelines that do not align with Maryland’s approach to vehicle modification, which allows for customization as long as compliance with safety and emissions regulations is maintained.
