More than 550,000 recalled vehicles remain on Baltimore's roads, many of them because owners don't know where to find recall information, according to MotorSafety.org.
The website, which aggregates news articles about vehicle recalls, has launched a tool that allows owners to check their vehicle recall status by vehicle identification number, or VIN.
If the vehicle in question is in recall, the website directs the owner to a certified dealer to address the problem.
"In many cases, people aren't even aware that their car is in recall," the site said in a statement. "This is a mass public concern that is dangerous not only for car owners, but for anyone else on the road."
The site is partnered with Recall Masters, which has its own listing of recalls by vehicle brand.
