The Pennsylvania Department of Transportation will stop issuing the stickers at the end of December , producing more than $3 million in annual savings of production and mail costs.
Motorists must still have their vehicles inspected and have to produce a valid registration card when asked by police.
Also in the new year, PennDOT will let motorists who renew online print out those registration cards.
The stickers were eliminated under a law passed in 2013.
Motorists are not required to scrape off or cover up the old stickers that are already on their license plate.
