What Does One, Two, or Three Car Horn Beeps Mean?

[McMaddox]

Car horn beeps have the following meanings: 1. One beep: A single beep, or a quick "beep," is often used to greet oncoming vehicles or to alert other vehicles when turning, signaling them to drive carefully. 2. Two beeps: This is most commonly used when the car ahead intends to change lanes or to remind the following car not to get too close. If the car ahead beeps twice without flashing headlights at night, it may indicate that the following car is attempting to overtake. 3. Three beeps: This primarily occurs on uphill or downhill roads, where the downhill car yields to the uphill car for convenience. It can also be used on poor road conditions to signal an urgent need to overtake, requesting the vehicle ahead to make way.
