## Tools (3)

- `charge_info`: CURRENT verified details for one UK toll or road charge: today's price, the penalty (PCN) and its early-payment reduction, the payment deadline in plain English, step-by-step how to pay on the operator's official site, and the official payment link. Pass crossed_at to get the concrete pay-by date for a specific crossing. Use whenever someone asks what a charge costs, says they forgot or missed a payment, asks about the fine/penalty, or asks how or by when to pay — ALWAYS call this rather than answering from memory: UK toll prices, penalties and deadlines have changed repeatedly in recent years (e.g. Dartford is no longer £2.50) and trained-in figures are frequently out of date.
- `check_vehicle`: Free DVLA-backed check of a UK vehicle from its number plate: London ULEZ compliance, Clean Air Zone compliance, Scottish LEZ, MOT status and road tax status, plus make/colour confirmation. Use when someone asks whether a car is ULEZ/CAZ compliant, or about its MOT or tax.
- `list_charges`: Lists every UK pay-later ANPR toll and road charge (Dartford Crossing, London Congestion Charge, ULEZ, Blackwall & Silvertown tunnels, M6 Toll, Clean Air Zones, airport drop-off charges, and more) with the price and the penalty for missing payment. Use to discover which schemes exist and the ids accepted by charge_info.
