Some lanes have special jobs: a shared center lane for left turns from both directions, reversible lanes that change direction with rush hour, and lanes reserved for buses, bikes or carpools.

Know the rule

In a shared center left-turn lane, the solid yellow outer lines mean you can't use the center lane for passing. The broken inner lines mean traffic from either direction may use it only to turn left.

Handbook p. 44 ↗

Using a shared center left-turn lane:

  • Check for vehicles ahead and check your mirrors
  • Signal left and check your left blind spot over your shoulder
  • Steer smoothly into the lane, but don't move in too soon
  • Choose a safe gap in oncoming traffic and make the turn
  • Watch for vehicles pulling out of entrances and side streets
Handbook p. 44 ↗

Know the rule

The longer you stay in the center lane, the more likely you'll meet someone coming the other way. Never use it for anything but turning left.

Handbook p. 44 ↗

Reversible lane

A lane that carries traffic one direction at some times and the opposite direction at others. It may have double dashed yellow lines, and overhead signals show its use.

Know the rule

Check which lanes you may use before entering a reversible lane, and stay alert: drivers going the other way could enter your lane by mistake.

Handbook p. 45 ↗

Know the rule

Reserved lanes are marked by signs and often a white diamond posted beside the road or painted on the lane.

Handbook p. 45 ↗

Reserved lane types:

  • 'Transit' or 'bus': buses only
  • 'Bicycle': reserved for bicyclists
  • HOV (High Occupancy Vehicle): vehicles with two or more people, unless signs say otherwise
  • 'HOV 3': at least three people must be in the vehicle

Put it into practice

You're alone in your car on a road with a lane marked by white diamonds and an 'HOV 3' sign. You can't use it: that lane requires at least three people in the vehicle during the posted days and hours.

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.

In a shared center left-turn lane, broken yellow lines on both sides mean:
  1. The lane is reserved for buses
  2. Only for left turns from either direction
  3. The lane is for passing
  4. The lane changes direction by time of day

Answer: Only for left turns from either direction

The shared center left-turn lane, marked with broken yellow lines on both sides, is only for left turns from either direction, never for passing or through travel.

Handbook p. 44 ↗
In a reversible lane, what does a red 'X' displayed above the lane mean?
  1. The lane is not available for use
  2. You may use the lane immediately
  3. The lane is currently changing direction
  4. The lane is for turning only

Answer: The lane is not available for use

A red X over a reversible lane means it is closed; a green arrow means you may use it, and a flashing yellow X restricts it to turning only.

Handbook p. 45 ↗
A flashing yellow 'X' above a reversible lane means the lane is:
  1. About to open in both directions
  2. Completely closed
  3. For turning only
  4. Fully open for through travel

Answer: For turning only

A flashing yellow X restricts the reversible lane to turning movements only, distinct from the steady yellow X (changing) or red X (closed).

Handbook p. 45 ↗
An 'HOV 3' sign on a reserved lane means:
  1. The lane closes after 3 p.m.
  2. Only three vehicles may use the lane at once
  3. Vehicles must travel at least 30 mph
  4. At least three occupants are required in the vehicle

Answer: At least three occupants are required in the vehicle

HOV signs specify a minimum occupancy; HOV 3 requires at least three occupants to legally use the lane.

Handbook p. 45 ↗
The solid yellow centerline in a shared center left-turn lane means you may use the lane for passing.
  1. True
  2. False

Answer: False

The solid yellow centerline means the center lane cannot be used for passing, only the broken yellow sections permit left turns.
