How should you respond to a driver who is not yielding the right of way?

Responding by slowing down and preparing to stop is the safest and most responsible action when encountering a driver who is not yielding the right of way. This approach allows you to avoid potential collisions and ensures that you can react appropriately to the situation. Yielding in this scenario can prevent accidents, as it prioritizes your safety and the safety of others on the road.

This response also encourages a defensive riding strategy, where anticipating the actions of other drivers can help you avoid dangerous situations. By slowing down, you're giving yourself more time to assess the situation and react accordingly, which is crucial on a motorcycle where visibility and maneuverability can be limited compared to larger vehicles.

In contrast, the other options could lead to dangerous situations. Speeding up could provoke the other driver or lead to a collision, signaling aggressively may escalate tensions without improving safety, and ignoring the driver and proceeding could result in a serious accident. It's always best to prioritize safety by taking defensive measures.
