If you are driving at the speed limit and another driver sounds their horn and starts to pass, what should you do?

When another driver sounds their horn and begins to pass while you are already driving at the speed limit, it is important to prioritize safety and facilitate the passing maneuver. Slowing down and allowing the other vehicle to pass is the appropriate action because it helps to create a safer environment for both drivers.

By reducing your speed slightly, you reduce the likelihood of a collision and give the other driver enough space to maneuver safely around you. This is particularly important in situations where visibility may be limited or where the passing lane may not be wide enough for both vehicles to comfortably occupy the same space at higher speeds.

In contrast, refusing to move over maintains the status quo, potentially escalating tension without resolving the situation amicably. Speeding up creates additional risks, as it could lead to an unsafe interaction between your vehicle and the one trying to pass. Sounding your horn and waving may not convey the right message or help the situation, as it does not provide clear intentions or promote a safe driving environment. Therefore, slowing down to allow the other vehicle to pass is the safest and most courteous choice.
