What does this safety sign installed before an intersection prohibit?
💡 Hint
For direction-ban signs, the key is which way the arrow under the diagonal line bends (Annex 6 of the Enforcement Rule). Read it exactly as seen from the driver's seat, and do not mix up arrows bent left or right with U-shaped or straight arrows.
Answer: ④
Explanation
This sign, an arrow bending to the right crossed out, prohibits turning right (Enforcement Rule Annex 6, No. 213). It is installed on the right side of the road where right turns are banned. An arrow bending left means no left turn, a U-shaped arrow means no U-turn, and a straight arrow means no going straight.
