- ARight turn is allowed only during specific hours.
- BRight turn is prohibited at all times.
- CRight turn is optional, but caution is advised.
- DRight turn is mandatory, follow the arrow.
Show answer & explanationAnswer & explanation
Correct answer: B. Right turn is prohibited at all times.
A red circle with a diagonal line (a prohibitory symbol) always means 'NO' or 'PROHIBITED' for the action depicted inside. Therefore, a right arrow within this symbol means no right turn.
Why the other options are wrong
- A. Time-based restrictions would typically be indicated by supplementary plaques.
- C. Optional actions are not indicated by prohibitory signs.
- D. Mandatory actions are indicated by solid white arrows without a prohibitory symbol.
