What Are Punishing Signals at Indian Traffic Lights?

🔴 Honk More, Wait Longer – Meet India’s “Punishing Signals”

In 2020, Mumbai Traffic Police launched an innovative campaign that stunned the world —
A traffic signal that punishes you for honking.

Yes, you read that right.

📢 The Problem: Relentless Honking at Red Lights

Even when the signal is red, many impatient drivers keep honking.
That’s not only annoying — it fuels urban noise pollution, causes stress, and even affects health.

💡 The Solution: The Punishing Signal

Here’s how it worked:

• A decibel meter was installed at key traffic signals
• If the honking volume crossed 85 dB, the red light timer would reset to 90 seconds
• The more you honk, the longer you wait. 🔄⏱️

This wasn’t just a prank—it was a smart behavioral nudge.

🎯 Impact of the Campaign

• Massive drop in honking during pilot trials
• Huge national and international attention 🌍
• Inspired other cities to think about tech-enabled civic awareness

Mumbai Traffic Police called it:

“Honk More, Wait More”

🤯 Did You Know?

• Mumbai’s average ambient noise near intersections regularly exceeds 100 dB
• WHO recommends a maximum of 53 dB for cities
• Chronic exposure to honking noise leads to anxiety, hearing damage, and even heart issues

🧠 The Larger Message:

It’s not just about waiting longer.
It’s about conditioning behavior to build quieter, healthier urban spaces.
Technology meets psychology — Indian-style. 🇮🇳
