Which statement about passing other vehicles is true?

Answer: C — Ensure sufficient room and visibility before passing

The statement that emphasizes the importance of ensuring sufficient room and visibility before passing is fundamentally correct. When a driver decides to pass another vehicle, they must first assess whether the road conditions, traffic, and visibility allow for a safe maneuver. Being aware of the surroundings means checking for oncoming traffic, obstacles, and ensuring that the lane is clear of vehicles. This precaution helps to prevent accidents that can occur due to sudden decisions or unforeseen circumstances. Additionally, having enough room ensures that when the driver re-enters the lane after passing, they can do so safely without cutting off the vehicle they passed or being too close to it. In contrast, passing without checking blind spots could lead to dangerous situations, as drivers might not be aware of nearby vehicles. Returning to the lane only after noticing headlights is risky, as it may not provide a full assessment of the space and safety needed to switch lanes. Furthermore, initiating a pass too close to the vehicle can increase the likelihood of misjudging the timing and distance required to safely maneuver, which can be hazardous.
