Over the Xmas break I have had cause to use the Dartford crossing a number of times, and the following article concerning a large number failing to pay – resulting in a £105 fine, makes interesting reading.

I can understand why so many fail to pay – some might very well be under the impression that the tolls are no longer in place, unless you take careful note of the signage at the crossing; especially when crossing via the bridge southbound, where there are no barrier/control gates.
Although payment can be made up until midnight the following day (of the crossing), it is easy to let such a payment slip your mind.
Having paid for my eight crossings at £2.50 a time (4 payments of £5), the receipts received via e-mail give only the date of payment, payment method (credit card) together with reference numbers. Nowhere on the receipts is the vehicle registration for which the crossing was purchased.
If at some later date, those who administer the fines for failure to pay, claim I have not paid – I will have no proof whatsoever that I paid for my crossing.
I predict a flood of complaints from motorists who have been fined, claiming that they have paid for the crossing, but like myself have proof of a payment to cross – but not proof that it covers the crossing for which they are being fined (watch this space).
