If you’re visiting the UK and driving across the Dartford Crossing — a near-inevitable part of any M25 trip — the cashless system catches a lot of overseas drivers out. There are no booths, the signage is easy to miss, and a £70 fine can follow you home. The good news: paying is straightforward once you know how, and this guide explains it for foreign-registered and hire cars, plus how enforcement reaches drivers abroad.
Key takeaways
- No booths: pay online or by phone by midnight the day after you cross.
- Foreign plates aren’t exempt — they’re traced via European vehicle databases.
- Hire cars: the rental company gets the PCN and usually bills you, often with an admin fee.
- Free 10pm–6am — if you crossed overnight, you owe nothing.
- Fines reach abroad — specialist contractors pursue overseas non-payment.
01 / PAYHow to pay in a foreign or hire car
The process is the same whatever your plate: pay the Dart Charge online at GOV.UK (search “Dart Charge”) or by phone, using your vehicle registration, by midnight the day after you cross. You can pay in advance if you know you’ll be crossing. There’s nowhere to pay at the crossing itself — that’s the part that catches visitors out, because they’re looking for booths that were removed in 2014.
02 / HIREIf you’re in a hire car
Pay it yourself using the hire car’s registration before the deadline — that’s cleanest. If you don’t, the rental company receives the PCN (they’re the registered keeper) and will usually pass the charge to you, often with an admin fee on top. Check your rental agreement; some firms offer toll-handling, but many simply bill you later, so paying promptly yourself is cheaper.
03 / ENFORCEDo fines really reach foreign drivers?
Yes. Foreign-registered vehicles are traced through European vehicle-registration databases, and a specialist contractor pursues overseas non-payment. Cross-border enforcement is slower and harder than domestic, which is why some charges go unrecovered — but ignoring a PCN is a gamble, especially if you visit the UK again. The simplest approach is just to pay the small toll on time.
04 / FREEThe free window & genuine errors
Remember the crossing is free between 10pm and 6am. If you crossed overnight, you owe nothing — and if you receive a PCN for a free-hours crossing, that’s a clear ground to appeal. Plate misreads happen too; if you’re fined for a crossing you didn’t make, you can challenge it (see our PCN appeals guide).
05 / SKIPLet someone else drive it
If you’re arriving at a Kent or London airport and would rather not deal with UK toll admin at all, a fixed-fare transfer includes the crossing charge and a local driver handles everything. As a Dartford-based, TfL-licensed operator, Rushxo does this crossing constantly — a stress-free option for visitors.

How do I pay the Dart Charge in a hire car?
