If you need to slow down or stop but others may not expect it, what should you do?

Tapping your brake pedal a few times is an effective way to signal your intention to slow down or stop to drivers behind you. This method allows you to alert following vehicles without causing confusion or alarm. By tapping the brakes, you're providing a clear and visual indication that you're about to reduce speed, which is particularly important in situations where other drivers may not anticipate your action.

Using hazard lights continuously is generally utilized for emergencies or to indicate a vehicle is stopped, not just to signal a slowdown. Steering into the shoulder is not advisable unless it is absolutely necessary, as it can present additional risks to both you and other drivers. Sounding your horn repeatedly may create alarm or confusion among other drivers rather than effectively conveying your intention to slow down. Therefore, the best practice in this scenario is to tap your brake pedal a few times to communicate your needs safely and effectively.
