  1. ARight turns are permitted only during certain hours.
  2. BYield to oncoming traffic before making a right turn.
  3. CNo right turn is allowed at this intersection.
  4. DRight turns are mandatory.
Show answer & explanation

Correct answer: C. No right turn is allowed at this intersection.

A red circle with a diagonal line through it is a universal symbol for 'NO' or 'PROHIBITED'. When placed over a right turn arrow, it specifically prohibits right turns at that location.

Why the other options are wrong

  • A. Time-restricted turns would be indicated by additional text on the sign, not this symbol.
  • B. Yielding before a right turn on red is a general rule, but this sign specifically prohibits the turn altogether.
  • D. Mandatory turns are indicated by a solid white arrow on a blue or green background, without the 'no' symbol.

Memory trick: Red circle and slash, means 'no' in a flash.
