If you’ve spotted a blue line painted on the street, here’s what it signifies.

Any driver knows how important it is to pay attention to road markings. Not following these markings is incredibly dangerous and could even lead to your de ath. Those who live in some areas of the U.S. may notice a new road marking appearing in the coming weeks: a thin blue line in the middle of the two yellow center lines in the road.

It turns out that this blue line is being painted on roads throughout Maryland to honor the heroic police officers who serve their communities! This is also a safety measure, as the line leads directly to the police station. However, it is also a nice gesture to let police officers who put their lives on the line every day are having their sacrifices be appreciated.
