The Congestion Charge is a fee for driving in central London to reduce traffic and emissions. The standard daily charge is £15, but it increases to £17.50 if paid after midnight on the day of travel. Some heavier vehicles may incur higher charges. Electric vehicles may qualify for exemptions or discounts. The Carr app allows you to check your vehicle's charges and pay in seconds using Apple or Google Pay.

The Dart Charge applies to vehicles using the Dartford Crossing between 6 am and 10 pm, every day, including weekends and holidays. Charges are £2.50 for cars, £3.00 for two-axle goods vehicles, £6.00 for vehicles with more than two axles, with discounts for account holders. Motorcycles and disabled-taxed vehicles are exempt. Payments must be made by midnight the day after the crossing to avoid penalties. Easily pay with Carr.
