Getting a tag fitted to your car can reduce the cost of major toll roads in the UK – we explain how it works.

What are tags?

Tags are small electronic devices which attach to your windscreen and are scanned when you pass a toll booth. Your bank account is charged with a reduced fee – and it means you won’t have to stop and pay by cash.

Each toll road will require its own tag – but not all toll roads have such schemes – especially private road tolls, where the owner can set their own charges.

Disabled blue badge holders

Registered blue badge holders are exempt from all the above fees.

You must apply for a Mobility Exemption Pass to cross the M6 for free, but only if you’re exempt from road tax and if you’re on the higher rate disability living allowance.
