Philadelphia drivers must get their cars inspected for emissions again

The US environmental regulators are approving Pennsylvania's plan to restart mandatory vehicle emissions inspections in five counties around Philadelphia. This means drivers in those counties will need to get their cars checked regularly to prove they meet air quality standards.

The US environmental regulators have been pushing states to enforce vehicle emissions rules for years. This approval means Pennsylvania is now legally bound to run these inspections, which directly affects car owners in the Philadelphia area. It also shows that the US environmental regulators are serious about making states meet air quality targets, even if it means restarting programs that were previously scaled back.
