- You must obey all traffic laws and regulations of the Commonwealth

- You must give pedestrians the right of way
- You must give pedestrians an audible signal before overtaking or passing them
- You may ride two abreast, but must facilitate passing traffic. This means riding single file when faster traffic wants to pass, or staying in the right-most lane on a multi-lane road

- Motorists are prohibited from making abrupt right turns (“right hooks”) at intersections and driveways after passing a cyclist
- Motorists must yield to oncoming bicyclists when making left turns. The law expressly includes yielding to bicyclists riding to the right of other traffic (e.g., on the shoulder), where they are legally permitted but may be more difficult for motorists to see.
- Motorists may not use the fact that bicyclists were riding to the right of traffic as a legal defense for causing a crash with a bicyclist.
- Motorists may not stand or park in an on-street bike path or lane designated by official signs or marking for the exclusive use of bicycles, except in a case of emergency For the exact requirements, use the link below to read the complete text of the laws pertaining to bicyclists and bicycling in Massachusetts.
