Railway crossing signs belong to which category of road signs?

• A. Warning signs
• B. Informational signs
• C. Regulatory signs
• D. Guide signs

Answer: (C)

Signs that regulate traffic impose a required action in a specific situation. A railway crossing sign communicates a rule you must follow at a crossing—slow down, be prepared to stop if signals or barriers require it, and proceed only when it’s safe. That kind of directive to driver behavior is what makes it regulatory.

Warning signs only alert you to a hazard ahead without mandating a particular action. Informational signs give details about services or destinations, and guide signs point you toward places or routes. So the railway crossing sign fits the regulatory category because it governs how you must act at that location.
