Even if cars are waiting in line, make sure the facility isn't closed due to a federal or state holiday. Times and dates are posted on the main office door, so if no one is there by the "open" time, then they are most likely closed for a Holiday. You can leave your car in line and walk to the office, which is usually at the drive in entrance area of the facility. It would be unusual for any MVA office or emissions facility to open late, without posting a notice or having a person notify the people in line. You can check for times and holiday close dates at all Federal or State facility websites. Gov employees work like clockwork. If they aren't there at open time, then the facility is closed. Go home and check their calendar for the next day you can go. And if you are late with your emissions test, then talk to the manager prior to testing. They are reasonable people and will help you with your situation.
Be patient.
MVAis closed on Columbus Day. FYI the state follows the US Government holiday schedule
As far the MVA Holiday Schedule indicates, MVA should be closed today. Check mva.maryland.gov/location/holiday.htm for more information.
Today is Columbus Day... Some local "Government" such a the MVA and emissions testing Locations might not be open
Keep waiting.
I'd say wait until it opens.
