Pavement lines tell you who is beside you and when you may cross. Yellow lines separate opposite directions and white lines separate lanes going your way. Passing is where these rules matter most.

Two-lane roads: solid yellow, and broken yellow with a one-direction no-passing zone
Multi-lane road markings (broken white lines)

Know the rule

Most roads with more than two lanes use broken white lines to separate the lanes.

Handbook p. 42 ↗

Know the rule

Change only one lane at a time and signal before turning or changing lanes. Don't weave between lanes. On highways, slower vehicles use the right lane; the left lane is for faster or passing vehicles.

Handbook p. 42 ↗

Changing lanes, step by step:

  • Make sure there is no traffic ahead of you in the lane you want
  • Check your mirrors for vehicles preparing to pass you
  • Briefly turn your head to check your blind spot and room in the next lane
  • Use your turn signal
  • Move smoothly into the new lane
Handbook p. 42 ↗

Passing, step by step:

  • Make sure the passing lane is clear of traffic
  • Check behind and to your left that no one is trying to pass you
  • Signal your intention to change lanes
  • Move over, accelerate, and keep going until you see the passed vehicle in your rearview mirror
  • Signal before returning to your original lane

100 feet

When passing, you must be back on the right side no less than this far before any oncoming vehicle

Handbook p. 43 ↗

Passing is illegal when:

  • A solid yellow line is on your side of the center line
  • A yellow pennant No Passing Zone sign (left side) or white rectangular Do Not Pass sign (right side) is posted
  • You're on or approaching a curve
  • You're approaching the crest of a hill or grade
  • You're within 100 feet of an intersection, railroad crossing, bridge, viaduct, or tunnel
Handbook p. 43 ↗

Know the rule

When another vehicle passes you on the left, let it pass safely and don't increase your speed.

Handbook p. 43 ↗

Put it into practice

You're behind a slow truck on a two-lane road with a broken yellow line on your side, but a bridge is 80 feet ahead. Don't pass. Passing is illegal within 100 feet of a bridge.
