Flashing Yellow Arrow Meaning: How to Turn Left Safely

You pull into the left-turn lane, and instead of a green arrow or a red one, a yellow arrow is blinking at you. Do you stop? Go? Wait for it to turn green? If you've hesitated at one of these signals, you're in good company. The flashing yellow arrow meaning is simple once you hear it, and learning it also clears up the rest of the traffic-signal family that permit tests love to mix together.

Flashing yellow arrow meaning

A flashing yellow arrow means you may turn in the direction of the arrow, but you must first yield to oncoming traffic and to pedestrians in the crosswalk. Oncoming cars have a green light. You don't have priority. You're allowed to turn only when there's a safe gap.

Think of it as a "permissive" turn. That's the opposite of a "protected" turn, when a solid green arrow stops oncoming traffic so you can turn freely.

You don't need to stop first if the way is clear, but you must be ready to. In practice:

1. Pull forward to the stop line or slightly into the intersection if your state allows it.
2. Keep your wheels pointed straight ahead while you wait, so a rear-end hit won't push you into oncoming traffic.
3. Watch oncoming traffic and the crosswalk you'll turn across.
4. Turn when there's a gap big enough to finish the turn without forcing anyone to brake.

How it differs from a solid green ball

For decades, the permissive left turn was shown with a plain green circle. The problem: a green light feels like "go," and some drivers turned without yielding. Others in the left lane saw the green ball meant for through traffic and assumed they had a protected turn.

The Federal Highway Administration allowed agencies to try the flashing yellow arrow in 2006 and then added it to the 2009 edition of the Manual on Uniform Traffic Control Devices, the national rulebook for signs and signals. The idea was that yellow already means caution, and an arrow tells left-turners the signal is for them specifically. Since then, many states and cities have switched their permissive left turns to this signal.

Here's the typical cycle at a four-section flashing yellow arrow signal:

Not every intersection shows all four. Some go straight from flashing yellow to solid yellow to red. The solid yellow arrow is your cue that you're losing the chance to turn, either because the protected phase is ending or because oncoming traffic is about to get a red.

Flashing red vs flashing yellow lights

Flashing circles (not arrows) show up when an intersection is running in a low-traffic mode at night, or at a single overhead beacon.

• Flashing red light: Treat it exactly like a stop sign. Come to a full stop, yield to anyone with the right of way, and go when it's safe.
• Flashing yellow light: Slow down and proceed with caution. You don't have to stop, but you must be prepared to.

When one direction flashes yellow and the other flashes red, the yellow side generally has priority. The red side stops and waits for a gap, just like a two-way stop. For a refresher on who goes first, see our guide to right of way rules.

Solid yellow: stop or go?

A steady yellow light or arrow means the signal is about to turn red. The rule in most driver manuals is: stop if you can do so safely; if you're too close to stop safely, proceed through carefully.

That second half matters. Slamming the brakes when you're already at the stop line can get you rear-ended. But speeding up to "beat the yellow" is how drivers end up running red lights. If you're watching the signal as you approach, you'll usually see it change early enough to make a calm decision.

Signals out or malfunctioning

When the power goes out and a signal is completely dark, most states require you to treat the intersection as an all-way stop. Every driver stops, and drivers take turns in the order they arrived. Our guide to 4-way stop rules explains the order.

If a police officer is directing traffic, follow the officer, even if the signal says something different. Officers override signals and signs.

Pedestrian signals

Left-turners at a flashing yellow arrow cross a crosswalk, so you need to know what pedestrians see:

• Walking person (white): Pedestrians may begin crossing. Expect people in the crosswalk you're turning across.
• Flashing hand or countdown numbers: Pedestrians shouldn't start crossing, but anyone already in the street may finish.
• Steady hand (orange): Pedestrians shouldn't be in the street.

Even with a steady hand, yield to anyone still in the crosswalk. A pedestrian finishing a crossing always has priority over a turning car.

Why left turns get so much attention

Left turns are tricky because you're crossing the path of oncoming traffic, often while judging speed and distance at the same time. That's also why examiners watch them so closely on road tests and why permit tests include several questions on them. Practice judging gaps with your supervising driver at quiet intersections first, and build up to busier ones.

Signals often appear alongside questions about turning on red. If you want the complete picture, read right turn on red rules next, then quiz yourself with our free practice tests. Getting the flashing yellow arrow meaning right on the test is easy points; getting it right at a real intersection is what keeps you safe.

Frequently asked questions

Do you have to stop at a flashing yellow arrow?

Not always. You must yield to oncoming traffic and pedestrians, so you stop only if the way isn't clear, then turn when there's a safe gap.

What does a flashing red light mean?

A flashing red light means the same as a stop sign: stop completely, yield to traffic with the right of way and proceed when safe.

What does a solid yellow arrow mean?

A solid yellow arrow warns that the turn phase is ending and the signal is about to change. Stop if you can do so safely; if you're already too close to stop, complete the turn carefully.
