The change from toll-payments to a new system called the Dart Charge has been hailed by the Highways Agency as a way to reduce congestion at Britain’s busiest toll.
But a new fine system means drivers can incur a maximum charge of £105 for failing to pay the £2.50 toll.
The standard charge for cars will increase by 50 pence to £2.50, while two axle goods will increase to £3 and multi-axle goods will increase to £6.
