Authorizes Commissioner of Transportation to allow painting of blue line between double yellow centerline marking on public roads.

This bill authorizes New Jersey's Commissioner of Transportation to allow the painting of a blue line in the space between double yellow centerlines on public roads. It directly affects the Commissioner, who gains discretionary authority to approve this specific marking on roads under the Department of Transportation's, county's, or municipality's jurisdiction. The key provision amends existing law to permit this blue line marking, overriding previous restrictions on traffic markings, while maintaining other requirements for uniform traffic control devices. The change applies immediately to all public highways within the state.
