A red circle with a slash over a right-curving arrow prohibits the movement shown: no right turn at this intersection. The red circle-and-slash is the international prohibition symbol, and the arrow inside tells you exactly which movement is banned.
These signs protect crossings and one-way patterns where a right turn would send you against traffic or across a busy pedestrian phase. The prohibition applies at the sign's intersection, including on a green light, unless a separate plaque limits it to certain hours.
Do not turn right at the intersection where the sign is posted, even if the light is green and the road looks clear. Continue straight or choose another lawful movement, and find your turn at the next intersection.
Questions pair it with No U-Turn, which uses the same red circle over a U-shaped arrow, and with No Turn On Red, which is a worded sign that only restricts turning during a red signal. The arrow inside the circle is what you read: it always shows the specific movement being prohibited.
This sign appears in 11 questions across 11 of our state banks, on Driver License practice tests. Start with your state:
What instruction is conveyed by the displayed right-turn arrow inside a red circle and slash?
Why: A red circle with a diagonal slash over a movement symbol indicates that the depicted movement is prohibited. Therefore, the proposed response is "Do not turn right".
Every practice test explains its answers this way. Pick your state and take one free; no sign-up.
Choose your stateThe right turn is prohibited at that intersection. The red circle and slash is the prohibition symbol, and the arrow shows the banned movement. It applies even when the signal is green.
No. The sign prohibits the movement itself, not a signal phase. A green light never overrides a regulatory prohibition sign.
No Turn On Red only forbids the turn while the signal is red; when the light turns green the turn is allowed. The R3-1 symbol sign forbids the right turn at all times unless a plaque says otherwise.
Usually because the turn would enter a one-way street against traffic, cross a heavily used crosswalk phase, or conflict with a transit or bicycle lane. The sign exists because the turn looks safe and is not.
Prohibition. Whatever appears under the slash, a turn arrow, a truck, a pedestrian symbol, that movement or user is not allowed. Reading the symbol inside is the whole skill the test checks.
