They’ve removed the toll booths from the A13 autoroute to keep the traffic flowing, but it does mean you have to pay online within 72 hours. This one is operated by SANEF - you can register a UK number plate online, and choose to either give them a credit card number (to auto debit) or just send you an email reminder online.

I set up the auto debit and got an email confirmation through of the toll.

Much less hassle than trying to align SWMBO with the tollbooth card reader! 2019 L405 Vogue SE 4.4 SDV8, Byron Blue

Get a toll tag - even easier and works on all the toll motorways & some car parks.

Mine even works in Spain
