Pedestrians and bicyclists are the road users most likely to be killed in a collision. The Manual spells out their duties as well as drivers' duties toward them. Instructors must know both sides, because students are often pedestrians and cyclists themselves.

Rules for Pedestrians

  • Use a crosswalk when one is available; state law requires it. At signals, press the button and wait for WALK. Intersections without buttons give WALK automatically.
  • Don't cross on DON'T WALK.
  • Before crossing, stop at the curb and look left, right and left again, even on a one-way street. Be especially alert where cars may turn right on red.
  • If you must step out between parked cars, stop and look first.
  • Use the sidewalk where there is one. Where there isn't, walk on the shoulder facing traffic.
  • Never walk along or across expressways, interstates or turnpikes.
  • Wear bright colors or reflective strips, especially at night.

Bicycle Laws: Riders' Rights and Duties

Bicyclists may use all public ways except limited-access or express state highways posted against bicycles, and must obey the same basic traffic laws as motorists. The Manual lists the rules from M.G.L. c. 85, s. 11B as amended by Chapter 525 of the Acts of 2008.

Rights

  • Use the full lane anywhere, anytime, on any street (except posted limited-access highways), even if there is a bike lane.
  • Keep to the right when passing a motor vehicle moving in the travel lane.
  • Ride on sidewalks outside business districts, unless banned locally.
  • Park on a way or sidewalk if it doesn't block vehicles or pedestrians.

Duties

TopicRule
DirectionRide with traffic unless signs or markings say otherwise
Signals and stopsStop at red lights and stop signs. Signal with either hand to stop or turn, but the signal need not be continuous, or made at all, if both hands are needed to control the bicycle
Sidewalks and pathsYield to pedestrians and give an audible signal before passing (no sirens or whistles)
Side by sideNo more than two abreast. On a road with more than one lane in your direction, stay in one lane and don't unnecessarily block passing traffic
SpacingKeep a safe distance from other cyclists, especially near intersections; slow down near crosswalks
SeatRide on or astride a permanent seat; passengers too, or in a trailer
Child passengersNo passenger aged 1 to 4, or weighing 40 lb or less, except in a "baby seat" with a harness, upright, with hands and feet protected from the spokes. No child under 1 may be carried. A tandem rider must reach the pedals and handlebars
HelmetsOperators and passengers under 16 must wear a helmet approved by the U.S. Consumer Product Safety Commission, secured on the head on any public way or bike path, unless the passenger rides in an enclosed trailer that protects the head
WarningsGive an audible warning (not a siren or whistle) when needed
TowingDon't let another vehicle pull the bicycle; tow only a bicycle trailer
CarryingDon't carry anything that interferes with control; keep one hand on the handlebars
BrakesMust be able to stop from 15 mph within 30 feet
Night lightsFrom ½ hour after sunset to ½ hour before sunrise: a white front lamp visible for 500 feet and a red rear light or reflector visible for 600 feet
Night reflectorsAlso pedal or ankle reflectors, or reflective material, visible for 600 feet from all sides
Handlebars and forkHandlebars no higher than the shoulders while gripped; no extending the fork beyond its original design
Crash reportsReport any crash with personal injury, or with property damage over $100, to the police where it happened

The Manual's safe-cycling advice

Ride in a straight line; ride at appropriate speeds and at walking speed on legal sidewalks; don't text and bike; yield to pedestrians; ride outside the "door zone," at least three feet from parked cars; pass other cyclists on the left; at intersections assume drivers can't see you; avoid riding beside or passing large vehicles, and never pass a moving tractor-trailer on the right; don't pass buses on the right; and don't wear headphones or earbuds in both ears. A proper helmet greatly reduces the risk of death and disabling injury.

Motorists' Duties Around Bicycles

DutyRule and source
Don't cut off after passingWhen passing a cyclist on your right, don't move back right until you have safely passed (c. 89, s. 2)
No abrupt turn after passingDon't turn right across a cyclist you just passed unless you are a safe distance ahead and can turn at a reasonable speed (c. 90, s. 14)
Don't squeeze in a narrow laneIf the lane is too narrow, be patient until you can use an adjacent lane or it is safe to pass. Stay at least four feet away (c. 89, s. 2)
Yield when turning leftYield to oncoming traffic, including bicycles, in the intersection or close enough to be a hazard (c. 90, s. 14)
Watch to your rightCyclists may legally ride to the right of traffic. It is no defense in a crash that the cyclist was on your right (c. 85, s. 11B)
Look before opening a doorDrivers and passengers can be fined up to $100 for opening a door into an oncoming bicycle (c. 90, s. 14)
Expect pairsCyclists may ride two abreast, but in one lane on multilane roads (c. 85, s. 11B)
Don't expect signalsCyclists don't always have to signal if both hands are needed (c. 85, s. 11B)

Bicyclists can be cited for traffic violations, though the citation doesn't affect their driving record, and motorists can be cited for these behaviors (section 6.2).

Bicycle Safety Habits to Build

  • Right hooks. Teach students to check the right mirror and blind spot for cyclists before every right turn, especially after passing one.
  • Left crosses. Before a left turn, look for oncoming cyclists, who are easy to miss beside cars.
  • Dooring. Make the Dutch Reach part of every parking stop (section 13.3).
