People on bicycles are harder to see than cars and easy to miss in your blind spot. Potholes, glass, litter, storm grates, railroad tracks and opened car doors can make a rider swerve or slow suddenly. Give them room and be ready to slow — you can't always predict what they'll do.

Sharing the road with bicycles

  • Never drive or park in a bike lane; you may cross it when turning or using an alley, driveway or private road
  • Don't move into or travel in a bike lane to prepare for a turn
  • Yield to bicyclists in a bike lane or on a sidewalk before turning across it
  • Yield to bicyclists at intersections just as you would to other vehicles
Handbook p. 58 ↗

Know the rule

At speeds greater than 35 mph, you may pass a person on a bicycle in your lane only if you leave enough distance to avoid contact if they were to fall.

Handbook p. 58 ↗

Know the rule

The same rules for passing vehicles apply to passing bicycles. If you can't pass safely, slow down and stay behind the bicycle until it's safe.

Handbook p. 59 ↗

Know the rule

Motorized wheelchairs, scooters and personal assistive mobility devices may use bike lanes and paths. Yield to them as you would to a bicyclist.

Handbook p. 59 ↗

Bike box

Usually a green painted box with a white bicycle symbol at an intersection, where bicyclists wait in front of cars at a red signal. Bike lanes leading to and from it may also be green.

Handbook p. 59 ↗

At a bike box

  • Stop for a traffic signal behind the bike box — not in it
  • No right turns are allowed at these intersections when the signal is red
  • Turning right on green? Signal and yield to people riding bicycles on your right

Sharrow

Two chevrons above a bicycle symbol painted on the road. It means the lane is shared and people riding bicycles may be in the road.

Put it into practice

You're doing 45 mph on a road with a broken yellow center line, and a bicyclist is riding in your lane. You may pass on the left when it's safe to pass, leaving enough distance that you wouldn't hit the rider if they fell.

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.

When may you cross a bike lane?
  1. Anytime there is no cyclist present
  2. Whenever traffic in your lane is slow
  3. Only to pass a left-turning vehicle or to park
  4. Only to turn, or to enter/exit an alley, driveway or private road

Answer: Only to turn, or to enter/exit an alley, driveway or private road

You may not drive or park in a bike lane, but you may cross one when turning or when entering or leaving an alley, driveway or private road.

Handbook p. 58 ↗
Before turning across a bike lane or sidewalk, you must:
  1. Yield to people riding bicycles
  2. Only yield if they are directly in front of you
  3. Speed up to turn ahead of them
  4. Yield only if a sign requires it

Answer: Yield to people riding bicycles

You must yield to cyclists before turning across their path.

Handbook p. 58 ↗
At speeds greater than 35 mph, when passing a person riding a bicycle in your lane, you must:
  1. Maintain your normal lane position
  2. Leave room so you won't hit them if they fall
  3. Slow to a complete stop first
  4. Leave at least 3 feet, the same as at lower speeds

Answer: Leave room so you won't hit them if they fall

Extra clearance is required at higher passing speeds.

Handbook p. 58 ↗
At a bike box, when the signal is red, a driver must:
  1. Stop inside the box, ahead of the bike lane
  2. Proceed slowly through the box
  3. Turn right if the way looks clear
  4. Stop behind the bike box, not in it

Answer: Stop behind the bike box, not in it

Stop behind the bike box, never inside it.

Handbook p. 59 ↗
At an intersection with a bike box, are right turns on red allowed?
  1. No, right on red is not allowed
  2. Yes, always allowed if cyclists are not present
  3. Yes, but only after a full stop
  4. Yes, if you yield to bikes first

Answer: No, right on red is not allowed

Right turns on red are prohibited at bike box intersections.

Handbook p. 59 ↗
A sharrow pavement marking indicates:
  1. A bike lane exclusively for bicycles
  2. A shared lane where cyclists may be present
  3. A pedestrian crossing only
  4. A lane where bikes must use the shoulder

Answer: A shared lane where cyclists may be present

Sharrows mark a shared travel lane for bikes and cars.
