What does this traffic symbol mean?"

Correct option is B

The correct answer is (b) There is a rough road ahead
Explanation:
. The traffic symbol shown in the image is a Cautionary (Warning) Sign.
. The symbol featuring a triangle with two consecutive humps or bumps indicates a "Rough Road".
. It warns the driver that the road surface ahead is uneven, damaged, or not well-maintained.
. Drivers are advised to reduce their speed to navigate the rough patch safely and avoid damage to the vehicle.
. This sign is distinct from the "Speed Breaker" sign, which typically shows a single hump.
Information Booster:
. Cautionary/Warning signs are always enclosed in a triangle with a red border.
. Mandatory/Regulatory signs (like "Stop" or "No Parking") are usually enclosed in a circle.
. Informatory signs (like "Hospital ahead" or "Petrol Pump") are usually enclosed in a rectangle or square.
Additional Knowledge:
(a) There is a vibration strip ahead
. Vibration strips (rumble strips) are usually marked directly on the road surface or indicated by text; there isn't a standard triangle symbol with two humps specifically for this.
(c) There are 2 speed breakers ahead
. While the image shows two humps, the standard definition in the Motor Vehicles Act rules for this specific icon is "Rough Road". The sign for a speed breaker typically has one single hump.
(d) There is a hilly road ahead
. Signs for hilly roads include "Steep Ascent" (car going up) or "Steep Descent" (car going down).
