Use the online wait times to gauge your arrival to this or any of the locations. In the past, I always follow my advice and find myself here in the late afternoon but had a conflict so I took a chance and came when they first open in the morning... BIG MISTAKE!!! Once you enter the gate, you have a slim to none chance of exiting with ease... So if you are on a time crunch, use the online wait times. There is an exit prior to getting your vehicle inspected but its in the far left lane and if you make it over to that point (without ticking people off) then you might as well just stay put.
I arrive just after 8am (when they opened) and 2 lanes were open attending to about 10+ cars. When I've come before, the wait has been no more than 10 mins, so I'm spoiled. It took just over an hour before I managed to be one of the next vehicles. My car only took just over 5 mins to inspect and came back clean so I was able to register online once I got back on my computer.
Depending on your vehicle, you are looking at getting the inspection done once every 2 years but if you're like me and have multiple cars with various due dates, then you see this place a bit more often.
The overall experience isn't so bad... or at least I've seen it a lot worse in other states. The MVD is located right next door so look at this location as your one stop shop for your vehicle and be sure to look online before coming as the system is really accurate.
