California Turn and U-Turn Rules for the DMV Permit Test

A turn can be legal at one California intersection and illegal a block away because of a sign, traffic signal, lane marking, or the type of road you are driving on.

For the California permit test, the easiest way to think about turns is:

Get into the correct lane, signal early, yield when required, and make sure signs and signals actually allow the turn.

U-turn questions add another layer because the answer can depend on whether you are in a residential district, business district, divided highway, or intersection.

When Are Turns and U-Turns Legal in California?

Before making a turn:

Check signs, signals, pavement arrows, and lane markings.
Signal at least 100 feet before the turn.
Move into the proper lane before reaching the intersection.
Reduce your speed before turning.
Check mirrors and blind spots.
Watch for pedestrians, bicyclists, motorcycles, and other vehicles.
Yield whenever another road user has the right-of-way.

A green light does not cancel a posted restriction. An empty intersection does not make a prohibited turn legal.

That distinction shows up frequently in permit-test questions.

Right Turns: Start and Finish Near the Right Edge

For a normal right turn, approach as close as practical to the right edge of the roadway.

If there is a designated right-turn lane, enter it where the lane opens.

Signal about 100 feet before the turn, slow down, look over your right shoulder, and watch carefully for pedestrians and bicyclists between your vehicle and the curb.

Complete the turn in the right lane unless signs or lane markings tell you otherwise. Do not swing wide into another traffic lane.

Turning Right Across a Bike Lane

California allows drivers to enter a bike lane when preparing for a right turn, but timing matters.

When it is safe, you may enter the bike lane within 200 feet of the turn.

Before moving into it:

Signal.
Check your mirrors.
Look over your right shoulder.
Watch for a bicyclist approaching from behind.
Merge behind the bicyclist when necessary.

Do not stay in the regular traffic lane until the corner and then suddenly cut across the bike lane.

For more situations involving cyclists and crosswalks, review California bicycle and pedestrian rules.

> Common Mistake: Treating the bike lane as something you should never enter. California specifically allows a driver to enter it within 200 feet of a turn when it is safe to do so.

Can You Turn Right on Red in California?

Usually, yes—but only after a complete stop.

At a steady circular red light:

1. Stop behind the limit line.
2. If there is no limit line, stop before the crosswalk.
3. If there is no crosswalk, stop before entering the intersection.
4. Check for a No Turn on Red sign.
5. Yield to pedestrians, bicyclists, and traffic with the right-of-way.
6. Turn only when it is safe.

A rolling stop is not enough.

> DMV Test Trap: A red light does not mean “slow down and turn if clear.” It means stop first. Only then may you consider turning right if the turn is allowed.

Red Light vs. Red Arrow

Do not confuse a circular red light with a red arrow.

At a red arrow, you may not turn in the direction of the arrow. Remain stopped until a green traffic signal or green arrow permits the movement.

That distinction is especially important on the permit test because an answer that would be correct at a regular red light can be wrong at a red arrow.

Left Turns: Yield Before Crossing Oncoming Traffic

For most left turns, move into the far-left lane or designated left-turn lane before reaching the intersection.

If you are using a two-way center left-turn lane, California allows you to enter it within 200 feet of the turn.

Signal, slow down, and watch for:

Oncoming vehicles
Motorcycles
Bicyclists
Pedestrians crossing the road

At a regular green light without a protected green arrow, you still must yield to oncoming traffic before turning.

A green light means the movement may be allowed. It does not automatically give a left-turning driver priority over oncoming traffic.

For a more complete explanation of who proceeds first, see California DMV right-of-way rules.

What Does a Green Arrow Mean?

A green arrow allows you to make a protected movement in the direction shown by the arrow.

Oncoming traffic should be stopped by its signal, but you should still scan the intersection before turning.

Pedestrians, bicyclists, or another vehicle may still be clearing the roadway.

Can You Turn Left on Red in California?

Yes—but only in one important situation.

You may turn left on red when:

You are turning from a one-way street onto another one-way street.

You must still:

Come to a complete stop.
Make sure no sign prohibits the turn.
Yield to pedestrians, bicyclists, and other traffic.
Turn only when it is safe.

A left turn on red is not generally allowed from a two-way street.

> Remember This:
> One-way street → one-way street = left on red may be allowed after stopping and yielding.

That is a classic California permit-test distinction.

When Is a U-Turn Legal in California?

A U-turn reverses your direction, so California places additional restrictions on where you may make one.

Use the far-left lane or the appropriate left-turn lane, signal, and make sure you have enough room and visibility to complete the maneuver safely.

California allows a U-turn in several situations.

At an Intersection

You may make a U-turn at an intersection on a green light or green arrow unless a No U-Turn sign prohibits it.

You must still yield when necessary and make sure the roadway is clear.

Across Double Yellow Lines

This rule surprises many permit-test applicants.

A U-turn may be made across a single set of double yellow lines when the maneuver is otherwise legal and safe.

Do not confuse that with two sets of double yellow lines. When two sets form a divided area or barrier, you may not drive across that dividing section to make a U-turn.

This is one reason understanding California lane markings matters.

In a Residential District

In a residential district, you may make a U-turn if no vehicle is approaching you from either direction within 200 feet.

A U-turn can also be allowed when a traffic signal, sign, or other traffic control protects you from approaching vehicles.

The number to remember for permit-test questions is:

200 feet.

On a Divided Highway

You may make a U-turn on a divided highway only where an opening has been provided in the center divider.

Do not drive over:

A curb
A dividing strip
A section of land
Two sets of double yellow lines

Use the designated opening.

When Is a U-Turn Illegal?

California prohibits U-turns in several specific situations.

Do not make a U-turn:

Where a No U-Turn sign is posted.
At or on a railroad crossing.
When you cannot see clearly for 200 feet in both directions.
On a one-way street.
In front of a fire station or by using a fire station driveway to turn around.
Across a divided-highway barrier, curb, strip of land, or two sets of double yellow lines.

U-Turns in Business Districts

Business districts have an additional restriction.

A U-turn is generally prohibited in a business district except:

At an intersection, or
On a divided highway where an opening has been provided.

A wide road or an empty street does not automatically make a midblock U-turn legal.

> DMV Test Trap: “There is no traffic coming” is not enough information to decide whether a U-turn is legal. First determine where the vehicle is located and whether a sign, road design, or visibility restriction prohibits the maneuver.

The 200-Foot Rules Are Easy to Mix Up

California uses 200 feet in several turn-related rules.

Here is a quick way to separate them:

These rules share the same number but apply to completely different situations.

Do not memorize “200 feet” by itself. Connect the number to the maneuver.

Signs and Lane Arrows Override the Default Rule

Turn rules assume that signs and pavement markings do not tell you something different.

A lane marked with a left-turn arrow is designated for that movement. A right-turn-only lane is not a lane for continuing straight.

Likewise:

No Turn on Red overrides the normal right-on-red rule.
No U-Turn prohibits the U-turn.
A red arrow prohibits turning in the arrow's direction.
Time-based signs may prohibit a turn only during certain hours.

Read the entire sign.

A permit-test question may deliberately mention that traffic is clear to distract you from a restriction posted at the intersection.

Quick Check: What Would You Do?

Question 1

You are approaching a right turn beside a bike lane. How early may you enter the bike lane?

Answer: Within 200 feet of the turn, when it is safe.

Check for bicyclists before merging.

Question 2

You are stopped at a red arrow and want to turn right. No traffic is coming. May you turn?

Answer: No.

A red arrow prohibits the turn until the signal allows the movement.

Question 3

You are on a one-way street and want to turn left onto another one-way street at a red light. There is no sign prohibiting the turn. Is it allowed?

Answer: It may be allowed after a complete stop and after yielding to pedestrians, bicyclists, and other traffic.

Question 4

You want to make a U-turn in a residential district. A vehicle is approaching 150 feet away.

May you turn?

Answer: No.

For this residential-district rule, no vehicle may be approaching from either direction within 200 feet.

A Simple Way to Solve Turn Questions on the Permit Test

When a California DMV question asks whether you can make a turn, work through four questions:

1. Am I in the correct lane?

Look at turn lanes, bike lanes, center left-turn lanes, and pavement arrows.

2. Does the signal allow the movement?

A green arrow, green light, red light, and red arrow do not all mean the same thing.

3. Does a sign or roadway rule prohibit the turn?

Look for No Turn on Red, No U-Turn, one-way restrictions, business-district rules, and divided-highway barriers.

4. Who must I yield to?

Even when the turn is legal, you may still need to wait for pedestrians, bicyclists, oncoming vehicles, or other traffic with the right-of-way.

This approach is more reliable than trying to memorize dozens of disconnected rules.

Remember the Pattern, Not Just the Numbers

For California turn questions, focus on the decision process:

Correct lane → correct signal → check restrictions → yield → turn safely.

For U-turns, add two more questions:

Is this location legal, and can I see far enough to make the maneuver safely?

Once you understand those patterns, questions about red lights, bike lanes, residential districts, business districts, and divided highways become much easier to separate.
