Center Turn Lane Rules: How to Use a Two-Way Left-Turn Lane

A center two-way left-turn lane is the shared lane in the middle of a road, marked with a solid line on the outside and a broken line on the inside, that drivers going either way use only to turn left. Center turn lane rules are simple: enter it close to your turn, don’t drive along it, and never use it to pass. Some states also set a maximum distance, such as 200 feet in California and 300 feet in Washington. This guide covers entering, how far you may travel and pulling out of a driveway into it, as of November 2026.

Key facts

• Markings: a solid yellow line on the outer edge and a broken yellow line on the inner edge, on both sides, often with white arrows pointing in opposite directions (federal MUTCD standard).
• Use: left turns (and in California, U-turns) by traffic from both directions. It is not a travel lane or passing lane.
• Distance limits: California 200 feet; Washington 300 feet. Many states set no figure but say don’t enter too soon.
• Biggest danger: a driver coming the other way in the same lane.

How do you recognize a two-way left-turn lane?

The federal Manual on Uniform Traffic Control Devices (MUTCD), which sets the standard for road markings across the US, describes it this way: each side of the lane has a normal broken yellow line and a normal solid yellow line, with the broken line toward the center lane and the solid line toward the traffic lane. Pairs of white arrows, one pointing each way, are used near the start of the lane, and signs may also mark it.

The quick test: solid on your side, broken on the inside, means you may cross into it to turn left. Don’t confuse it with a painted median or double solid yellow lines, which you must not drive in. For the full line system, see US pavement markings.

How far can you drive in a center turn lane?

Texas’s rule covers three-lane roads in general, not only marked turn lanes. Where the lane is marked as a two-way left-turn lane, the markings control its use. If your state isn’t listed, check the turning section of your handbook (state guides are linked from learning to drive in the USA). If no figure is given, treat a short distance, such as the 200 feet California uses, as a safe habit.

Entering the center turn lane: step by step

1. Signal left early. Pennsylvania says at least 3 to 4 seconds before you enter the lane.
2. Check mirrors and your left blind spot. California tells you to look over your shoulder before moving in.
3. Look ahead along the lane for drivers coming toward you in the same lane, and for drivers pulling out of driveways on your left.
4. Move in completely. Don’t leave the back of your car sticking out into the travel lane.
5. Slow and stop if needed, opposite the driveway or street you want, keeping your wheels straight while you wait.
6. Turn only when the gap is big enough in oncoming traffic, and the driveway or crosswalk you are turning across is clear of pedestrians.

Pulling out of a driveway into the center lane

Pennsylvania’s manual allows drivers turning left out of a cross street or driveway to use the center lane to finish the turn before merging into traffic. Washington’s law also describes the lane as for vehicles turning left from or into the roadway. If you do this:

1. Wait for a gap in the traffic coming from your left.
2. Check the center lane in both directions. Drivers already in it, preparing to turn, have it before you.
3. Pull fully into the center lane and stop if you need to.
4. Signal right, check your mirrors and blind spot, then merge into the travel lane when there is a gap. Don’t ride along the center lane looking for one.

If traffic is heavy or your state’s handbook doesn’t mention this move, it is safer to wait for a gap in both directions and turn straight into the travel lane.

What you must not do

• Use it to pass or overtake. California and Washington both say so, and Pennsylvania calls it a turning lane only.
• Drive along it to skip a line of traffic, or as a merge lane for a long stretch.
• Enter it far from your turn.
• Turn left from the travel lane next to it. Washington’s law says that where a center turn lane is provided, no vehicle may turn left from any other lane.

Scenario: two drivers, one lane

You move into the center lane to turn left into a gas station. A car ahead, coming the other way, has also moved into the center lane to turn into a store on its left. You are now pointed at each other. The rule from every handbook checked is the same: watch for oncoming drivers in the lane before you enter, enter close to your turn, and stop if you have to. The shorter the time you spend in the lane, the less likely this is.

Common questions

Can you drive in the center turn lane to merge into traffic?

Briefly, after turning out of a driveway or cross street, some states allow it (Pennsylvania’s manual describes it). Don’t drive along the lane as a merge lane. California limits any driving in it to 200 feet and Washington to 300 feet.

How far before a turn can you enter the center turn lane?

California says within 200 feet of the turn. Washington limits travel in the lane to 300 feet. Other states just say not too soon.

Can you pass a car using the center turn lane?

No. California calls it “not a regular traffic lane or passing lane”, and Washington’s law bans overtaking in it.

Can you make a U-turn from the center turn lane?

California’s handbook says the center left turn lane can be used to prepare for a U-turn. You still need a legal place to finish it. See U-turn rules.

Who has the right of way in a center turn lane?

California says to respect the right of way of any vehicle, bicyclist or motorcyclist already in the lane, and always yield to pedestrians. When you turn across oncoming traffic, you yield to it. See left-turn yield rules.

Is the center turn lane on the road test?

Examiners can route you along roads with one. They watch for a signal, a blind-spot check, entering close to the turn and entering fully. A pass in the center lane would be an illegal maneuver.
