Everyday 24 hours
It should its 24h this thing works 7 days a week 24h you wanna go in the very early mornings if you dont want to wait more than 30 min and be patient sometimes the machine breaks down but after a few minutes it works again I took my car like a week ago and after waiting for almost an hour when it was my turn the machine didnt work so I decided to wait and then it started working so I got in line again for another hour and finally got my car tested...make sure before you leave your house to locate the obd port in your car because if you dont you will have a hard time when you are there trying to locate it ...good look
