In Massachusetts, the dooring law makes it illegal to open your car door into a passing cyclist or pedestrian, with a fine of up to $100.
What Is the Massachusetts Dooring Law?
It’s called “dooring,” and state law takes it seriously. Under Chapter 90, Section 14, no person may open a car door unless it’s reasonably safe to do so without getting in the way of other traffic, and the statute specifically names bicyclists and pedestrians.
Notice the words “no person.” The rule isn’t just for drivers. A passenger who swings a door open into the bike lane can be on the hook too.
Why does it matter? A suddenly opened door can stop a cyclist cold or send them into traffic, and these crashes can cause serious injuries. An easy habit helps: the “Dutch reach.” Open your door with the hand farthest from it, which naturally turns your body so you look back before you open.
Knowing the Massachusetts dooring law before you open your door protects cyclists and pedestrians, and it protects you from a fine. If a door crash has already hurt you, a Boston bicycle accident lawyer at Larson Law can explain your options.
