- Bkerb marking
- Cobject marking
- Dreflector unit markingCorrect
Solution
Concept
Reflector units reflect vehicle headlight and act as hazard and guide markings for safe night driving.
Step-by-step solution
1. Road markings are of four types: pavement markings, kerb markings, object markings and reflector unit markings. 2. Reflector units (like road studs or cat's eyes) shine back the headlight of vehicles. 3. They are used to show hazards and to guide drivers at night. 4. So the answer is reflector unit marking. Answer is D.
Explanation
Reflector units are small reflecting devices fixed on the road or roadside. At night they reflect the headlights and clearly show the road edge, lanes and hazards. So they work as hazard and guide markings for night driving.
Why the other options are wrong
A: Pavement markings are painted lines for lanes, centre lines, stop lines etc. and are not mainly for night guidance. B: Kerb markings show kerbs and no-parking zones. C: Object markings mark obstructions like piers and poles near the road.
Shortcut
Night driving + hazard and guide = reflector units.
Common mistake
Choosing object marking because it also marks hazards, but it is not specially meant for night guidance.
Correct answer: D) reflector unit marking
