Road Lines

Road lines are used to help drivers maintain their lane, aid them in turning, or prevent them from entering a wrong lane/hazardous area.

There are yellow and white lines: yellow lines separate traffic flowing in opposing direction, white lines separate traffic flowing in the same direction. Yellow lines can also be used to separate an HOV lane and they can also be used to indicate the left side of the road on an on/off ramp.


  • 'Passing' is the act of moving over a road line.
  • 'Overtaking' is the act of passing another vehicle.

Note: Yellow and white lines used in parking lots or other areas to mark parking spaces and other similar areas do not follow the same restrictions and do not permit/prohibit the actions listed below.

Violating the road line regulations listed below can result in a citation of $25 to $125. You cannot be cited the charge mentioned on the infractions Trello alongside this if it is more specific.

List of Lines

Yellow and white lines have the exact same restrictions put onto them; the only difference is that they separate bi- and unidirectional traffic.

  • Quadruple lines (either broken or continuous) prohibit:
    • Passing.
    • Overtaking.
    • U-turns.

This shall not apply if it is a broken line setup which allows for a reversible lane, allowing vehicles to drive between the two lines depending on time or sign/signal indication.

  • Double continuous lines prohibit:
    • Passing UNLESS YOU ARE TURNING LEFT.
    • Overtaking.

(these may be used to separate HOV lanes and may be white)

  • Double lines with one side continuous and one side broken permit the following if the vehicle is on the side of the broken lines:
    • Overtaking.
    • Passing.
  • They permit the following regardless of which side you're on:
    • Passing ONLY WHEN TURNING LEFT.
    • U-turns.
  • A single continuous line must:
    • Not be passed if it may endanger other traffic.
    • Not be passed if it is in correlation with the line setup above (double lines with one side broken and one continuous).
  • The line should:
    • Not be passed at all.
  • The following are, however, legally permitted:
    • Passing.
    • Overtaking.
    • U-turns.

If the passing of a single continuous line causes a hindrance or endangers other traffic, you may be cited for up to $150 + any other charges.

Passing a single continuous line may be necessary to safely enter a turn lane.

  • Broken single lines permit:
    • Passing.
    • Overtaking.
    • U-turns.

(care must be taken to not hinder or endanger opposing traffic)

  • Short broken single lines indicate either:
    • A merging/splitting lane, or
    • Act as a guide line in intersections

Intersection guide lines have legal effect and must be followed.

The arrows in red show the path vehicles must take when turning.
