Riding a Bike in the City
1. What are the traffic laws and regulations governing bicycling in Cambridge?
In general, bicyclists have the same rights and responsibilities as motorists when traveling on the public ways in Massachusetts. There are a few differences, such as those surrounding bicycling on sidewalks; using lights at night; and wearing helmets (see below for links). Bicyclists have the right to travel on all public ways except limited access highways.

2. Am I allowed to bicycle on the sidewalk?
State law permits bicyclists to travel on sidewalks in the interest of safety except as directed by local ordinance. In general, it is more appropriate and prudent to bicycle in the street, and Cambridge is making every effort to making the city streets safe and comfortable for bicycling. However, it is recognized that there are times when sidewalk riding will be used, for example, with young children. Cambridge traffic regulations require that bicyclists on sidewalks travel at a walking speed and yield to pedestrians.
Sidewalk riding is not permitted in the business districts of Harvard Square, Central Square, Porter Square, Inman Square, Huron Ave., and sections of Mass. Ave. north of Harvard Square.

3. What types of lights do I need on my bike and when do I need to use them?
Massachusetts law requires bicyclists to use a white front light from 30 minutes after sunset to 30 minutes before sunrise. Visibility is a critical matter for bicyclists. Nearly half of all cycling deaths nationally involve cyclists riding at night without lights, although only 3% of biking occurs after dark. It is important for cyclists to understand that front lights are important primarily so that other travelers can see them. Reflectors alone do not make a bicycle visible at night. Light from a reflector bounces directly back to where it came from, so reflectors are of no use when car headlights are not pointed directly at the bike. Only a front light makes the bicycle visible to pedestrians, to drivers about to open a car door into the street, and to drivers who are backing up.
The law also requires a red rear light or reflector and reflectors on the pedals or reflective material on the rider’s ankles. .Lights are strongly encouraged on the back of the bicycle, as these provide stronger visibility.

4. What are the laws about wearing helmets?
Massachusetts law requires any person 16 years old or younger riding a bicycle to wear a helmet. Helmets are a good idea for everyone. Wearing a bicycle helmet is the single most effective way to lower your risk of traumatic brain injury and death when you or your children ride a bike. A helmet protects your head by absorbing the force of an impact that otherwise would hurt you. Thick plastic foam inside the hard outer shell of the helmet provides padding so the helmet takes the force of the blow, instead of your head.

5. How can I register my bike?
Bicycle registration is free and is done through the Cambridge Police Department. It is very important to register your bike; should it ever be taken, it is through the registration that the bicycle can be returned to you.

on How to Register a Bike
6. How can I get a “Watch for Bikes” sticker?
The City of Cambridge distributes “Watch for Bikes” decals to put on the side and/or rear view mirrors of cars, to remind drivers to Watch for Bikes when turning and opening car doors. You can get one by sending an email to cseiderman@cambridgema.gov or calling 617/349-4604.
Bicycle Parking
7. Where am I allowed to park my bicycle?
Bicycles are permitted to park on a bicycle rack or street sign pole, against a building, or on another facility specifically intended for that purpose. Under no circumstances shall a bicycle obstruct the pedestrian path of travel or handicap access ramps. A parked bicycle must leave at least a 36-inch obstruction-free path of travel. Bicycles are not permitted to be parked to: fire hydrants, hand railings, benches, trees, trash receptacles and parking meters.
8. Is there a limit to how long a bicycle is permitted to be parked on the sidewalk/public way?
Time limits for bicycle parking apply in the city’s designated business district:; Harvard and Central Squares. See maps of the districts for exact streets that are included.
Bicycles are permitted to be parked for 72 hours (3 days), after which they may be tagged. Once a bicycle is tagged, an owner will have 72 hours (3 days) to remove it, or it may be taken by DPW and stored for a minimum of 30 days prior to disposal.
9. How can I report an abandoned bike?
If you see a bicycle on public property that appears to be abandoned – not used, in dysfunctional condition – you can report it to the DPW. In order to be removed, the bicycle must meet the legal definition of being abandoned. DPW will tag it and remove it, after which it will be held at DPW for a minimum of 30 days prior to disposal.
10. My bicycle is gone from where I parked it. What do I do?
You can call two places: the Department of Public Works (DPW), 617/349-4800 or the Police Department, 617/349-3204. If you think your bicycle may have been taken by DPW because you left it parked illegally (e. g., attached to a bench or tree) or because it was left in a business district for a long time, try DPW first. If you think it more likely that it was stolen, and that none of the above apply, contact the Police Department. Retrieving your bicycle in either case will be much easier if registered.
