Under what condition is it permissible to pass another vehicle?

Answer: B — When your lane is separated by a broken yellow line

Passing another vehicle is permissible when your lane is separated by a broken yellow line. This marking indicates that the roadway is intended for two-directional traffic and allows for passing when safe to do so. The broken line signifies that you are allowed to change lanes or pass another vehicle, provided that it is clear and safe. In contrast, traffic lights being green does not specifically indicate whether passing is allowed or safe, as the situation may depend on other factors such as the presence of pedestrians or ongoing traffic. The speed limit, while important for ensuring safe driving, does not dictate the rules for passing; it simply sets a maximum speed for traveling, which may not align with safe passing procedures. Nighttime driving also doesn’t inherently affect the legality of passing; it is more about visibility and road conditions than the time of day itself.
