A broken white line indicates that changing lanes is permitted if the maneuver can be done safely. This type of line is used to separate lanes of traffic moving in the same direction, typically on multi-lane roadways where lane changing is a natural part of traffic flow. Understanding these markings is crucial for safe driving, as they guide drivers on when lane changes are allowed, helping to maintain traffic order and efficiency. Following these regulations ensures that lane changes are made without disrupting the surrounding traffic.
