Trivia: In what situation are you NOT supposed to use hazard lights?
When parked in front of a hydrant
When changing a tire
When your car breaks down
In a funeral procession
The correct answer is When parked in front of a hydrant
So why is this answer correct? : You might see it a lot, but simply turning on your hazards does not make an illegal parking job suddenly OK. You can still be ticketed for double parking or parking in front of a hydrant while your hazards are on. Hazard lights flash continuously to indicate that a car is immobile, and can be used when your car breaks down or when changing a tire. In most funeral processions, drivers simply turn their headlights on, but sometimes hazards are also used.
