Final answer:
A broken white line on the highway indicates that passing is allowed, and drivers may safely change lanes when it is appropriate to do so, always respecting the posted speed limits and traffic signals.
Step-by-step explanation:
A broken white line on the highway means that passing is allowed. This type of marking designates lanes where traffic is moving in the same direction, and drivers can cross the lines to change lanes or overtake other vehicles when it is safe to do so. The broken lines offer drivers flexibility to adjust their lane position in response to the traffic conditions, always ensuring they do so safely and without causing disruption to the traffic flow.
It is important to note that while the broken white lines indicate that passing is allowed, drivers should still adhere to the posted speed limits and perform all maneuvers with caution. Traffic signals and signs, such as a red traffic light or a speed limit sign, are also there to enforce safe driving behaviors and should be respected at all times to maintain road safety.
