How are tolls charged on the UK motorways ?

Charging standards: There are toll roads in the UK, including the M6 motorway in the north of Birmingham, and some tunnels, bridges, etc. leading to the city center of London and Durham. The M6 has a single price for the entire section: £5.50 for cars, and £11 for buses and trucks. There are discounts on weekends and off-peak hours (from 11 pm to 6 am). For example, the price for cars on weekends is £4.80, and it is reduced to £3.80 during off-peak hours. Payment methods: 1. Manual toll booth (Change given): Cash is accepted, but these are few. 2. No change booth (No change): There is a basket at the entrance where you can throw in coins to open the barrier, so it's best to have some change ready. 3. Credit card toll booth (with a symbol of a hand holding a card): Insert the credit card and press the receipt button (Receipt) to open the barrier automatically. 4. Electronic payment booth (TAG): You need to apply for a high-speed toll card in advance, and the fee will be automatically deducted when passing through.
