What defines a legal overtaking maneuver on a controlled access highway?

A legal overtaking maneuver on a controlled access highway is defined by the requirement to stay within the lane. This ensures that vehicles can pass one another safely without encroaching on adjacent lanes or the roadway shoulder, which could endanger other drivers. Staying within the designated lanes maintains a clear and organized flow of traffic and reduces the potential for collisions.

The other options suggest practices that would not comply with safe driving regulations on a controlled access highway. For example, using signs as a guide is important for navigation but does not specifically pertain to the mechanics of overtaking. Using the shoulder is generally illegal for overtaking as it can create dangerous situations. Honking to alert others does not apply to the act of overtaking, as it should not be used in conjunction with this maneuver to signal intentions or assert one’s right to pass. Overall, maintaining lane discipline is fundamental for safety in such traffic environments.
