Northampton is a community that supports and encourages bicycling, both for recreational purposes and as a means of transportation. The city is home to miles of bike paths that take riders all over the city. We are also nestled in the five-college area and attract cyclists who are connected to one of the local campuses. With the high volume of vehicle, bicycle and foot traffic, it is essential that everyone works together to reduce the risk of accidents. In an effort to prevent and reduce bicycle-related accidents, this section of our website highlights some of the most important laws related to bicycling and operating a motor vehicle around cyclists.
Motor Vehicle Operators
- Motorists cannot “door” cyclists. This means that before opening the doors to a vehicle, motorists must make sure that this doesn’t interfere with the flow of traffic, whether it be vehicles, pedestrians or cyclists. (MGL C.90§14)
- Motorists cannot “right-hook” cyclists after passing them. After passing a cyclist travelling in the same direction, motorists cannot make a right turn unless they are a safe distance away from that cyclist. (MGL C.90§14)
- Motorists cannot “squeeze out” a cyclist. If a motorist cannot overtake and pass a cyclist at a safe distance in the same lane, the driver must either use the adjacent lane if it can be done safely, or wait for a safe opportunity to pass. (MGL C.90§14)
- After overtaking and passing a cyclist, a motorist cannot return to the right lane until it is safe to do so. (MGL C.89§2)
These laws are punishable by a $50 fine.
