The Dart Charge for Class B vehicles on registered accounts is to increase by 20% from 1 October 2018.
Currently car owners using the Dartford Crossing who have a pre-paid account pay £1.67 per crossing, a third lower than the £2.50 paid by those without an account.
However, drivers have received an email informing them from October 1 they will be charged £2, 20% lower than the standard rate. Account holder charges for all other vehicle classes will stay the same.
If no payment of the toll is made online by midnight the day after your crossing a fine of £70 is imposed, which is halved if paid within 14 days or increased to £108 if not paid within 28 days.
