What does the following safety sign mean?
💡 Hint
Regulatory signs that ban a direction of travel are told apart by the arrow under the diagonal line (Annex 6 of the Enforcement Rule). A straight arrow, a bent arrow and a U-shaped arrow each mean something different; the no-overtaking sign shows cars, and the no-entry sign is a white bar on red.
Answer: ②
Explanation
This sign, a straight upward arrow crossed out, prohibits going straight (Enforcement Rule Annex 6, No. 212). It is installed on the right side of the road where going straight must be banned. The no-overtaking sign shows a curved arrow and a car, the no-U-turn sign a U-shaped arrow, and the no-entry sign a white bar on a red background.
