Match the following markings drawn on the carriage way with their significances.

S.No.	Type of Line	S.No.	Significance
A.	Double longitudinal solid lines	1.	Guiding and regulating line
B.	Broken longitudinal lines	2.	Edge line
C.	Solid longitudinal lines	3.	Indicate centre line or lane-marking for multi-lane roads
		4.	Indicate maximum restriction and are only to be crossed in case of emergency

Explanation:

1. Double Longitudinal Solid Lines (A - 4):

   • Significance: These lines indicate a maximum restriction area on the road, where crossing the lines is prohibited under normal conditions. Vehicles should not cross these lines except in emergencies, such as when directed by authorities or to avoid an obstacle.

2. Broken Longitudinal Lines (B - 3):

   • Significance: Broken lines serve as lane markings and can be crossed by vehicles for overtaking or changing lanes.
   • These are commonly used as centerlines on multi-lane roads to separate traffic moving in opposite directions.

3. Solid Longitudinal Lines (C - 1):

   • Significance: A single solid line is used to guide and regulate traffic.
   • It indicates that drivers should generally stay within their lane but may cross the line with caution, typically used in situations where lane-changing should be minimized.
