Which of the following statements about traffic marking classification is INCORRECT?

Explanation: 

• Yellow markings are not exclusively regulatory. They are primarily used to separate traffic flows in opposite directions and indicate no-overtaking zones, centerlines, etc.

• White markings are used for lane separation (same direction), edge lines, guidance, and also regulatory purposes (like stop lines, turn arrows).

Additional Information

Purpose of Traffic Markings

Traffic markings are used on roads to:

• Regulate traffic flow

• Ensure safety

• Guide and warn drivers

• Indicate road conditions and lane usage

Classification of Road Markings

Longitudinal Markings

• Run parallel to the direction of traffic.

• Examples: lane lines, centerlines, edge lines.

• Help in lane discipline, no-overtaking zones, and direction control.

Transverse Markings

• Run across the roadway.

• Examples: stop lines, pedestrian crossings, give way (yield) lines.

• Used to control movement at intersections and crossings.

Hazard/Object Markings

• Indicate presence of obstacles such as medians, bridge piers, or narrowings.

• Painted diagonally or chevron-style to draw attention.

Arrow Markings & Symbols

• Show specific instructions like turn directions, lane usage, etc.

Color Coding

• White Lines: Separate lanes in the same direction, mark edges, guide vehicles.

• Yellow Lines: Separate opposing traffic, indicate no-passing zones or medians.

• Red/Black: Used sparingly, often in special contexts (e.g., bus lanes or emergency zones).

• Other Colors (like Blue): Can indicate reserved parking, disabled zones, etc.
