Solution
Concept
As per IRC:67, the STOP sign is an octagon with red background and white border.
Step-by-step solution
1. Recall the shapes of IRC road signs. 2. Octagon shape is used only for the STOP sign. 3. The STOP sign has a red background, white border and the white word STOP. 4. So the answer is (B) stop.
Explanation
The STOP sign is the only octagon-shaped sign in IRC:67. It has a red background with a white border and white letters. Its special shape helps drivers know it even from the back or in poor light.
Why the other options are wrong
A: Accident prone area is a warning sign, which is an equilateral triangle with red border. C: No parking is a circular prohibitory sign with red border. D: Yield (Give Way) is an inverted triangle with red border.
Shortcut
Octagon = STOP. Inverted triangle = GIVE WAY. Circle = prohibitory or mandatory. Triangle = warning.
Common mistake
Students confuse STOP with GIVE WAY because both are priority signs. GIVE WAY is an inverted triangle, not an octagon.
Correct answer: B) stop
