When is it safe to pass other vehicles on the right side?

Passing on the right side is safe when the street or highway has two or more lanes for traffic in the direction you are traveling. This allows for adequate space and visibility to overtake another vehicle safely without placing yourself or others at risk of collision. In such situations, you often have a clearer understanding of the traffic pattern, making it easier to judge the timing and distance you need for a safe maneuver.

In contrast, passing on one-lane roads can be hazardous since there is insufficient space to safely overtake without encroaching on the opposite lane, where incoming traffic could pose a danger. Similarly, in residential areas, conditions such as parked cars, pedestrians, and tighter street layouts may not provide the necessary visibility or space to execute a safe pass. While it may seem logical to pass when the vehicle in front is turning left, this maneuver may also not be safe unless there is a clear and legal opportunity to do so, particularly if the roadway does not facilitate multiple lanes for traffic.
