What is the proper action for a driver intending to pass another vehicle?

When a driver intends to pass another vehicle, using the turn signal is the proper action. This communication tool informs other drivers, including the one being passed, of your intentions to change lanes or maneuver around them. Proper signaling is crucial for safety on the road, as it helps to prevent accidents by making your intentions clear to others.

Using hazard lights is inappropriate in this scenario because hazard lights are meant to indicate a stopped vehicle or a situation that requires caution. Honking before passing is unnecessary and can be misinterpreted; it might startle other drivers rather than alert them. Slowing down before passing is also not the standard action; instead, maintaining or slightly increasing your speed is often required to pass safely and efficiently while ensuring that other drivers understand your actions. Thus, using the turn signal is the best and most correct method for indicating a passing maneuver.
