What does the following traffic sign indicate? [Image: Triangular warning sign indicating Narrow Bridge Ahead]
- ARailway crossing
- BNarrow bridge aheadCorrect
- CMajor Road
- DOne way
Solution
Concept
Warning (cautionary) signs are triangular in shape. The narrow bridge sign warns drivers that the carriageway narrows at a bridge ahead.
Step-by-step solution
1. A triangular shape means a cautionary (warning) sign. 2. The symbol shows the road narrowing at a bridge. 3. So the sign means Narrow Bridge Ahead.
Explanation
Under IRC:67, warning signs are triangles with a red border. The symbol shown tells drivers that a narrow bridge is ahead, so they should slow down and take care.
Why the other options are wrong
A: The railway crossing sign uses a gate or train symbol. C: The major road sign shows a cross road where one road is thicker. D: One way is a rectangular informatory or mandatory sign with an arrow, not a triangle.
Shortcut
Triangle = warning. Look at the symbol to see what the danger is.
Common mistake
Confusing the narrow bridge sign with the narrow road ahead sign.
Correct answer: B) Narrow bridge ahead
