If you are driving in a funeral procession, what should you do?

Keep your headlights on dip
Keep your hazard lights on
Toot your horn
Drive with your windows down

In New Zealand, if you are driving in a funeral procession, the correct practice is to keep your headlights on low beam (Option 1). The primary purpose of this rule is to ensure that other members of the funeral party and other road users can clearly identify the vehicles participating in the funeral. This enhances road safety and also expresses respect for the deceased.
