When another vehicle is passing, what is the appropriate action for the driver being passed?

Moving to the right edge of the pavement when another vehicle is passing is the safest and most courteous action a driver can take. This maneuver allows the passing vehicle to have more space to overtake safely, thereby reducing the risk of a collision. By positioning your vehicle closer to the right edge, you create a clear path for the other driver, who may be accelerating past you, and help maintain a smooth flow of traffic. This action is especially important on narrow roads where space is limited.

In contrast, slowing down and keeping driving could confuse the passing driver or lead to a position where they might attempt a pass in a less than ideal scenario. Accelerating while being passed can also create dangerous conditions, as it may push the passing vehicle into a potentially risky situation or encourage reckless behavior. Maintaining a constant speed and moving to the left of the lane may not provide enough space for a safe pass, especially if there's insufficient room for the other vehicle to navigate around effectively.
