I have obtained one of those Sanef Tolling devices for use on French motorways later this year. It is fitted on the windscreen in the shaded area around the rear view mirror on the CX-5, and automatically activates the "Telepeage" lane barrier when exiting the French autoroutes - I think there is something similar in operation for the Dartford Tunnel/Bridge tolls, but obviously a different company. The toll is then taken at the end of each month via Direct Debit from your bank account. There are a few set up costs but, in theory, sounds like a foolproof way of getting along the motorway system and avoiding the horrendous queues that are waiting to pay in cash or by card, particularly in August when we are travelling. This is the first time I will have used this system, and will feed back in September when we return - if there is anyone that has used the system already, your thoughts and experience (particularly with the CX-5) would be really appreciated - the last thing I want to do is get it wrong and face the wrath of countless French folk who are being delayed by me!
