Final answer:
When another driver is attempting to pass while you're driving at the speed limit, it is safest to slow down and allow them to pass. Refusing to move over or confronting the other driver can create traffic hazards and is not recommended. Prioritizing safety and adhering to defensive driving techniques is crucial.
Step-by-step explanation:
If you are driving at the speed limit and another driver sounds their horn and starts to pass, the appropriate action would be to slow down and allow them to pass.
This is the safest response to ensure both drivers remain unharmed and to keep traffic flowing smoothly. You mentioned that the speed limit is being adhered to; thus, there's no need to speed up, and refusing to move over or becoming confrontational by sounding your horn could escalate the situation unnecessarily and lead to a traffic hazard.
It's essential to always prioritize safety on the road and to follow driving best practices when interacting with other drivers. By slowing down slightly, you ensure that the other driver has plenty of space to safely return to the lane. This action aligns with the rules of defensive driving and helps prevent potential accidents.
