What is a key step before passing another vehicle?

The correct answer emphasizes the importance of checking for oncoming traffic and assessing road conditions before attempting to pass another vehicle. This step is crucial for ensuring safety on the road. When you check for oncoming vehicles, you assess whether there is sufficient space to safely maneuver without risking a collision. Additionally, evaluating road conditions can help you identify any potential hazards, such as curves, intersections, or obstacles that might put you or others at risk during the passing maneuver.

The other options suggest actions that disregard safety protocols. Simply signaling without ensuring the road is clear can lead to dangerous situations, as you may attempt to pass in the presence of oncoming traffic. Accelerating without looking is reckless and can lead to serious accidents, as it completely ignores the necessary checks for safety. Passing regardless of conditions neglects the responsibility of a safe driving practice, potentially endangering not only yourself but also other road users.
