Some lanes have special jobs: the passing lane, carpool lanes, center left turn lanes and turnouts. Each has rules on who may use it and for how long.

Know the rule

On a multilane road, the passing lane is the far-left lane, closest to the center divider.

Handbook p. 21 ↗

HOV (carpool) lane

A lane reserved for carpools, buses, motorcycles, or low-emission vehicles with decals. Marked with a diamond symbol and the words Carpool Lane.

Handbook p. 21 ↗

You may use an HOV lane if:

  • You have the minimum number of people posted on signs (signs also list the hours HOV rules apply)
  • You drive a low or zero emission vehicle displaying a special DMV-issued decal
  • You ride a motorcycle (unless otherwise posted)

Know the rule

A center left turn lane is not a regular traffic lane or a passing lane.

Handbook p. 22 ↗

To turn left from a center left turn lane:

  • Look for vehicles coming toward you in the center left turn lane
  • Signal
  • Look over your shoulder to check your blind spots
  • Merge completely into the lane so you do not block traffic
  • Turn when it is safe

You're towing a boat slowly up a two-lane mountain road where passing is unsafe, and you count six cars behind you. You must pull into the next turnout to let them pass.
