Here’s a new government rule I can get behind. A new rule from the Federal Highway Administration has set the first minimum standard for the reflectivity of pavement markings on roadways. Given that a quarter of all driving is at night but half of all deaths are, the ruling is designed to make sure the markings on the road are visible in all kinds of conditions. Roadways with speed limits over 35 miles per hour need markings with a reflectivity of 50 millicandelas per square meter per lux, and highways with speeds of 70 miles per hour or over need 100 millicandelas per square meter per lux. Pavement markings are a combination of paint and glass beads that bounce light back off of headlights.
