What are the required hours of operation for an inspection station?

The correct answer specifies that inspection stations must operate during regular daytime business hours from at least 8 AM to 4 PM to comply with Maryland regulations. This timeframe ensures that the public has adequate access to vehicle inspection services during hours that are typical for consumer needs. Setting up an operation window of this nature allows for maximum convenience as it aligns with typical working hours, accommodating individuals who may need to have their vehicles inspected before or after traditional work schedules.

The other options either restrict the hours too much or specify weekend operations that do not align with the typical weekday accessibility required by most customers seeking vehicle inspections.
