Here in PA, like the other PA drivers/owners, I pay for the car registration each year or I can make a 2-year payment, but no discount, if I chose to do so and then every 4 years, I have to get a new driver's license, or I can chose to get just a 2-year license because of my age.
Then, I have to have my cars inspected annually for both mechanical and omissions. Each require their separate w/s sticker. We no longer get a new plate sticker each year to show that we have paid our registration fees. Instead, police cars have scanners mounted on them that scans the tag for the officer to find out if the registration is current.
As a cop, I preferred the sticker. When computers go down, their useless. Mobile computers work a bit different than the computers we are used to using at home.
