How many flashes of hazard lights to express thanks?
2 Answers
Flash the hazard lights three times after merging to express gratitude. Here is relevant information: 1. Flash headlights once when following a vehicle: This is mainly used at red light intersections to remind the vehicle ahead that the light has changed and they can proceed. When waiting at a traffic light, the vehicle in front might not notice the light change from red to green due to distraction. Some drivers might honk directly, which isn't very friendly. Flashing the headlights once to remind the driver ahead feels more polite. 2. Flash headlights twice during oncoming traffic: This is mainly to remind the oncoming vehicle to turn off their high beams. Driving at night is particularly annoying when facing vehicles with high beams on, as it makes it hard to keep eyes open. Regardless of whether it's intentional, flashing the high beams twice during oncoming traffic can serve as a reminder to the other driver.
I've been driving for over a decade and I'm quite familiar with hazard lights usage. Usually when someone gives way or helps on the road, I'll quickly flash the hazards once or twice to say thanks. This practice is particularly common during long-distance driving, especially among truck drivers who use it most frequently. However, be careful not to overuse it - randomly flashing on highways might make others think your car has problems, affecting safety. I only flash when the other party can see me, and use the horn when they're too far away. Local customs may vary - I noticed flashing is more common when driving in southern regions. Also worth reminding: hazard lights are mainly for emergency stops, brief flashes are sufficient for courtesy, keeping them on too long might actually distract following vehicles.
