A NO RIGHT TURN sign means drivers may not turn right from the approach where the sign applies. It is a regulatory movement-prohibition sign. The restriction applies even if the intersection looks clear or the traffic signal is green, unless a valid sign or direction specifically provides an exception.
1. What Does a NO RIGHT TURN Sign Mean?
The NO RIGHT TURN sign is a regulatory traffic sign that prohibits a driver from making a right turn from the approach where it applies. In the U.S. Manual on Uniform Traffic Control Devices (MUTCD), the standard sign is identified as R3-1 and belongs to the movement-prohibition sign group.
The sign does not mean that every direction of travel is closed. It specifically prohibits the right-turn movement. Drivers must follow other signs, lane-use arrows, traffic signals, and local rules as well.
Right turns are prohibited
Do not turn right from the approach controlled by the sign.
It is a regulatory sign
It communicates a movement that drivers are not permitted to make.
Other controls still apply
Obey traffic signals, lane arrows, pavement markings, and any additional restrictions.
Choose another route
Continue safely and use a permitted street or intersection to reach your destination.
2. How to Recognize a NO RIGHT TURN Sign
In the U.S. MUTCD, the NO RIGHT TURN sign is designated R3-1. It is typically a white regulatory sign with a black right-turn arrow crossed by a red circle and diagonal red bar.
- Symbol: An arrow showing a right-turn movement.
- Prohibition marking: A red circle and diagonal slash across the arrow.
- Meaning: The depicted right turn is prohibited at the location where the sign applies.
Some locations may use supplemental plaques or time-specific electronic signs. Read all accompanying information instead of assuming the restriction applies only at certain hours.
3. Where Are NO RIGHT TURN Signs Commonly Posted?
Traffic authorities may install a NO RIGHT TURN sign at an intersection approach where the right-turn movement is prohibited. You may see one in situations such as:
Busy intersections
A right turn may be restricted to reduce conflicts with opposing traffic or keep vehicles moving.
One-way streets
A prohibited right turn may prevent drivers from entering a street against its permitted direction.
Near transit or rail facilities
Restrictions may help prevent conflicts with tracks, buses, or designated travel paths.
Roads with limited visibility
A right turn may be prohibited where sight distance or intersection geometry makes the movement unsafe.
Under MUTCD guidance, a NO RIGHT TURN sign should be placed where drivers who might intend to make the movement can easily see it. Actual placement and enforcement depend on the road authority and applicable state or local law.
4. What Movement Does the Sign Prohibit?
The sign prohibits the right-turn movement from the approach it controls. It does not automatically prohibit going straight or turning left, provided those movements are allowed by other signs, signals, lane markings, and traffic laws.
| Driving movement | Does NO RIGHT TURN prohibit it? | What to remember |
|---|---|---|
| Turning right at the signed approach | Yes | Do not make the prohibited right turn. |
| Proceeding straight | Not by this sign alone | Check signals and lane-use signs. |
| Turning left | Not by this sign alone | Make the movement only if it is otherwise legal and safe. |
| Making a U-turn | Not necessarily | A separate NO U-TURN sign or local rule may prohibit it. |
5. What Should You Do When You See the Sign?
- Identify the sign early. Look for the red prohibition symbol over the right-turn arrow.
- Do not enter a right-turn path. Stay in a lane that permits your intended movement.
- Obey the traffic signal. A green light does not cancel a NO RIGHT TURN restriction.
- Check supplemental signs. Look for time limits, vehicle exceptions, lane-use signs, and other instructions.
- Continue safely. If you need to reach a street on your right, follow a legal alternate route.
6. NO RIGHT TURN vs. Other Turn-Prohibition Signs
These regulatory signs prohibit different movements. Recognizing the difference is useful for everyday driving and DMV knowledge tests.
| Sign | MUTCD code | What it prohibits |
|---|---|---|
| NO RIGHT TURN | R3-1 | A right turn from the approach where it applies. |
| NO U-TURN | R3-4 | A U-turn at the signed location. |
| NO TURNS | R3-3 | Turning movements covered by the sign. |
| NO LEFT TURN | R3-2 | A left turn from the approach where it applies. |
A NO RIGHT TURN sign is not the same as a NO U-TURN sign. The MUTCD identifies these as separate movement-prohibition signs. The combined R3-18 sign prohibits both U-turns and left turns, not right turns. Follow the symbol displayed and any additional signs at the intersection.
7. Real-World Driving Situations
Example A: You are approaching a green light
You want to turn right, but a NO RIGHT TURN sign is posted. Correct action: Do not turn right. Follow a permitted lane and direction.
Example B: The road looks empty
You see no oncoming vehicles and think the turn is safe. Correct action: The sign still prohibits the right turn. Traffic being absent does not remove the restriction.
Example C: You need to reach a business on the right
The entrance is just beyond the intersection. Correct action: Continue and find a legal alternate entrance or route. Do not make the prohibited turn.
Example D: A lane arrow points straight
You are in a lane marked for straight-through traffic and see NO RIGHT TURN. Correct action: Proceed straight if the signal and other controls permit it.
Example E: Another driver turns right
A vehicle ahead ignores the sign. Correct action: Do not copy the driver. Follow the posted restriction.
8. Common Mistakes Drivers Make
- Assuming a green light allows the turn: A green signal does not cancel a regulatory prohibition sign.
- Confusing NO RIGHT TURN with NO U-TURN: They prohibit different movements.
- Following another driver: Another motorist's action does not make a prohibited turn legal.
- Ignoring lane arrows: Lane-use signs and pavement markings also control permitted movements.
- Making a last-second lane change: Sudden movements can cause collisions. Plan ahead and continue safely.
- Assuming the sign is optional when the road is empty: The restriction still applies.
9. Safety Tips for Drivers
Scan ahead
Look for regulatory signs before reaching the intersection.
Choose the correct lane
Position your vehicle early for a permitted movement.
Follow every control
Combine signs, traffic lights, lane arrows, and pavement markings.
Never rush a turn
If you miss a turn, continue safely and choose another route.

11. Frequently Asked Questions
What does a NO RIGHT TURN sign mean?
It means drivers may not turn right from the approach where the sign applies.
What is the MUTCD code for the NO RIGHT TURN sign?
The U.S. MUTCD identifies the standard NO RIGHT TURN sign as R3-1.
Can I turn right if the traffic light is green?
Not where a NO RIGHT TURN sign applies. A green signal does not cancel the posted movement prohibition.
Does NO RIGHT TURN also mean NO U-TURN?
Not automatically. NO RIGHT TURN and NO U-TURN are separate signs. A separate sign or local law may prohibit U-turns.
Can I go straight when I see a NO RIGHT TURN sign?
The sign alone prohibits the right turn, not necessarily straight-through travel. Follow lane arrows, signals, and all other traffic controls.
Can I turn left at the intersection?
The NO RIGHT TURN sign alone does not prohibit a left turn, but other signs, signals, lane markings, or laws may restrict it.
Where are NO RIGHT TURN signs posted?
They are used at approaches where the right-turn movement is prohibited. The MUTCD provides guidance on sign placement so drivers intending to turn can see the sign.
What does the combined R3-18 sign mean?
It prohibits both U-turns and left turns. It is a different sign from NO RIGHT TURN.
What should I do if I miss my street?
Continue safely and use another route or intersection where the desired movement is permitted. Do not make a sudden or prohibited turn.
Are turn restrictions the same in every state?
Traffic laws can vary by state and locality. Consult the current official driver handbook for the place where you drive.
