Which of the following statements is true regarding lane markings on the road?

A solid white line between lanes of traffic indeed signifies that you should stay in your lane. This marking is used to separate lanes of traffic moving in the same direction and indicates that lane changes are discouraged, although they are technically permitted if absolutely necessary. The presence of this line helps maintain orderly traffic flow and enhances safety by discouraging frequent lane changes.

In contrast, a solid yellow line typically indicates that passing is not allowed, thus emphasizing the safe distance drivers should maintain from oncoming traffic. Meanwhile, a dashed yellow line indicates that passing is permitted when it is safe to do so. A solid white line allowing for free lane changes is misleading, as it directly contradicts the function of the solid white line intended to help regulate traffic. Understanding these markings is critical for safe driving practices and compliance with traffic laws.
