When passing another vehicle, you must:

Flash your headlights
Use your horn
Make sure you have enough room
Wave to the other driver

The correct answer is: Make sure you have enough room

Passing another vehicle requires patience and caution. Flashing your headlights or using your horn can be seen as aggressive and may startle the other driver. Waving to the other driver is a friendly gesture, but it is not necessary while passing. The most important thing to remember when passing another vehicle is to make sure you have enough room to do so safely. This means checking your blind spots and ensuring there is enough space between your vehicle and the other vehicle before changing lanes. This is why choice C is the correct answer.
