Cyclists fare best when they act and are treated as drivers of vehicles. Knowing what a bicyclist must do helps you predict their moves, and sharrows tell you when they're expected to use the full lane.

Bicycle drivers sharing the road must:

  • Obey all traffic signals, laws and signs, just as if driving a car
  • At night, use a bright headlight and a good rear reflector
  • Travel in the same direction as traffic, turning left and right the way cars do
  • Use hand signals to show turning and stopping
Handbook p. 29 ↗
Bicycle hand signals
Bicycle hand signals: left turn, stop, right turn

Special considerations for bicycling in traffic:

  • Bicycles can be hard for motorists to see: wear bright colors, use proper lighting, be predictable
  • The safest way to ride is as part of traffic, with the flow of the normal traffic pattern
  • Adults should, and minors must, wear a well-fitting helmet
Handbook p. 29 ↗

Know the rule

Minors must wear a well-fitting helmet when bicycling; adults should.

Handbook p. 29 ↗

Sharrows

Shared lane pavement markings, painted where a road is too narrow for side-by-side sharing. Bicyclists are encouraged to take the whole lane and motorists shall yield as needed.

Handbook p. 29 ↗
Bicycles may use full lane
Sharrow: bicycle symbol with double chevrons

As a motorist, with sharrows:

  • Slow down and yield to bicyclists in the roadway
  • Pass only when the road is wide enough for bicyclists to move right
  • Try to give at least five feet of clearance when passing
Handbook p. 29 ↗

As a bicyclist, with sharrows:

  • You may ride on the center of the sharrow
  • Keep a safe distance from the "door zone" of parked cars
  • Move right to let vehicles pass when it is safe
Handbook p. 29 ↗

Put it into practice

You're driving on a narrow street painted with sharrows and a cyclist is riding right on the markings. Slow down and yield; pass only when there's room for the cyclist to move right and for you to give five feet.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

Who is required to wear a bicycle helmet under New Mexico law?
  1. Minors
  2. No one, it's always optional
  3. All riders, of any age
  4. Only riders on highways

Answer: Minors

Adults should, and minors must, wear a well-fitting helmet.

Handbook p. 29 ↗
What are 'sharrows'?
  1. A reserved bicycle parking area
  2. Shared-lane pavement markings
  3. A special bike-only traffic signal
  4. Arrows marking a bike-only lane

Answer: Shared-lane pavement markings

'Sharrows' are 'shared lane pavement markings' painted when a road is too narrow to share side by side.

Handbook p. 29 ↗
What should a motorist do when they see sharrows painted on the road?
  1. Slow down and yield to bicyclists
  2. Assume bicyclists will always move right
  3. Pass in the same lane without slowing
  4. Ignore them, since they are only for bicyclists

Answer: Slow down and yield to bicyclists

As a motorist, slow down and yield to bicyclists in the roadway where you see sharrows.

Handbook p. 29 ↗
New Mexico law requires only adult cyclists, not minors, to wear a helmet.
  1. True
  2. False

Answer: False

Minors must wear a helmet; it's only recommended (not required) for adults.
