About Warning signs J: triangle, not a command: which statement is WRONG?
Sign J22 warns of cyclists and moped riders.
J-signs are warning signs, not order/prohibition signs; J8 only warns, it does not regulate priority — that follows from B-signs, shark's teeth, or the main rule.
J16 = roadworks. Level crossing with barriers is J10.
J10 = level crossing WITH barriers. Dangerous crossroads is J8.
Explanation
Book p.245-246 (H14) - **J22 = pedestrian crossing. Cyclists and moped riders is J24.** Trap: vulnerable-road-user category read too broadly.
