Which danger warning sign is the only one that does not have a triangular shape?
Signage: Vertical signs
Explanation
Warning signs: exception for level crossings
- General rule: warning signs are triangular.
- Exception: those that warn of the proximity of a level crossing (with or without barriers) and those that mark its location are not triangular:
- Approach panels: rectangular, with red stripes indicating the distance.
- St. Andrew’s Cross: X-shaped, marks the exact point of the crossing.
Key idea: the warning of proximity to a level crossing breaks the triangle rule.
