Final answer:
When two or more lanes of travel are permitted in the same direction, a broken white line is used to indicate that drivers are allowed to change lanes and pass other vehicles when it is safe to do so.
Step-by-step explanation:
When two or more lanes of travel are permitted in the same direction, a broken white line is used. The purpose of the broken white line is to indicate that drivers are allowed to change lanes and pass other vehicles when it is safe to do so. It serves as a visual separation between lanes and helps maintain orderly traffic flow.
Road Marking is defined as lines, patterns, words except road signs which are applied or attached to the carriageway or kerbs or to objects within or adjacent to the carriageway for Controlling, Warning, Guiding and Informing the road users.
Dash lines allow changing lanes. Zigzag lanes mean deceleration. The yellow line is the center line, which separates traffic in the opposite direction. Solid line means "do not overtake", and double solid line has the meaning of further emphasis on that way.
