The Congestion Charge is a fee charged to vehicles driving in certain areas of a city during peak hours. It aims to reduce traffic congestion, improve air quality, and encourage the use of public transport. Cities like London have implemented this system to manage urban traffic effectively. Drivers entering the designated zone must pay the charge, which can vary based on the time of day. Exemptions may apply for certain vehicles, such as electric cars or those carrying disabled passengers. The revenue generated is often reinvested into public transport and infrastructure improvements.
