Mobility & Curb Rules in Somerville, MA

Every city handles mobility & curb rules a little differently. In Somerville, Massachusetts, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Bike Lane Rules

In Somerville, bicycles and other non-motorized conveyances have exclusive right-of-way in designated bicycle lanes, and motor vehicles are banned from driving or parking in them. Police and Parking Control Officers enforce the ban under Traffic Code Article XIII.

Key details: Governing section: Traffic Code Art. XIII, Sec. 13-6. Motor vehicles in bike lanes: Prohibited outright. Pedestrians in bike lanes: Barred except to cross. Parking in bike lane: Listed tow violation, Sec. 5-1(x). Enforcement: Police Dept. and Parking Control Officers.

Blocking or parking in a marked bicycle lane violates Sections 5-1(x) and 10-5(x) and exposes the vehicle to towing under Article X procedures, with the registered owner held prima facie liable. Motorists who drive or stand in a bike lane violate Section 13-6 directly; the Police Department enforces moving violations and Parking Control Officers enforce the parking components under Section 13-9.

Red-Light Cameras

Somerville's ordinance lets the Police Department mail civil-penalty notices to vehicle owners caught by photographic monitoring systems running red lights or speeding through camera zones, with contested cases going before an administrative hearing officer.

Key details: Governing article: Traffic Code Art. XVIII, Sec. 18-2/18-3. Liability basis: Registered owner, civil not criminal. Notice deadline: Mailed within 40 days. Contest deadline: 21 days after notice. Repeat-offense increase: +$100 for 3rd violation/12 mo..

A civil penalty tied to G.L. c. 89, Section 9 (red light) or G.L. c. 90, Section 17 (speed) applies per violation, rising $100 for a third offense within 12 months; a $50 late-payment penalty and $50 hearing costs can be added under Section 18-4. Appeals of a liability finding go to Somerville District Court within 31 days.

This is one of the stricter rules in Somerville's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Shared E-Scooter Rules

Somerville bars anyone under 16 from operating a motorized scooter and caps speed at 25 mph on any city way. Riders must wear bicycle-standard helmets, use bike lanes when available, and never ride on sidewalks or after dark.

Key details: Governing section: Traffic Code Art. XVII, Sec. 17-3. Minimum age: 16, with license/permit. Speed cap: 25 m.p.h.. Sidewalk riding: Prohibited. First-offense fine: $25.00.

Riding a motorized scooter on a sidewalk, after dark, above 25 mph, or without a helmet violates Section 17-3 and is enforced by the Somerville Police Department. Fines run $25 for a first offense, $25-$50 for a second, and $50-$100 for a third or later offense within the same enforcement period, per Section 17-3(o).

This is one of the stricter rules in Somerville's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
