The Dartford Crossing — consisting of the Queen Elizabeth II Bridge and the Dartford Tunnel — is one of the most important road connections in the South East of England, linking Kent and Essex across the River Thames. Since the Dart Charge system was introduced, drivers must pay electronically to cross, with no toll booths and no cash collection.
Whether you are a commuter who uses the M25 daily, a logistics driver passing through the region, or a visitor exploring Kent and Essex, understanding how Dart Charge works is essential to avoid unexpected penalty notices. This independent guide covers every aspect of the system.

Comprehensive Guides
Getting Started
The Dartford Crossing is the only fixed road connection across the Thames east of London. The Dart Charge system replaced physical toll booths in 2014. All drivers — including those with a valid resident's account — must make arrangements before crossing or pay within 28 days.
Payment Guide
If you crossed the Dartford without a pre-paid account, you have up to 28 days to pay online at dartcharge.co.uk. The process takes about 5 minutes and accepts Visa, Mastercard, and American Express cards. You will need your vehicle registration and the date of crossing.
Costs & Charges
Standard car charges at the Dartford Crossing are £2.50 per crossing for most vehicles. Motorcycles travel free. Higher charges apply to heavy goods vehicles — up to £5.00 depending on axle count. Charges apply 24 hours a day, 7 days a week with no exemptions for weekends or public holidays.
Account Setup
A Dart Charge account with a Dart-Tag device gives you a discounted crossing rate and removes the risk of forgetting to pay. The account is free, requires no monthly subscription, and the tag is posted to you within 5 working days of registration.
Penalties
If you cross the Dartford and do not set up a payment method within 28 days, a penalty charge notice is automatically issued. The initial fine is £70, reduced to £35 if paid within 21 days. If unpaid after a further period, the fine rises to £105 and enforcement action may follow.
Auto Pay
The Dart Charge account system allows drivers to choose between a pre-paid balance or a monthly direct debit. Pre-paid accounts give you full control and the discounted rate. Monthly billing suits regular commuters who cross multiple times per week and want no ongoing management.
ULEZ & Environment
The Dartford Crossing falls within London's Ultra Low Emission Zone expanded boundary. If your vehicle does not meet the Euro 4 (petrol) or Euro 6 (diesel) emission standards, you will need to pay the ULEZ charge of £12.50 per day in addition to the Dart Charge crossing fee.
Tips
If you are new to the Dartford Crossing, here are the most important things to know before you go: plan your payment method in advance, do not rely on finding a way to pay on the day, and be aware that the bridge is closed to high-sided vehicles during strong winds.
Practical Advice
Create a free Dart Charge account before your first crossing. Add funds or set up auto-reload so payment is always handled automatically.
The QE2 Bridge closes to high-sided vehicles at 50 mph+ winds. Check traffic updates before departing, particularly in autumn and winter.
Manage your account, check crossing history, top up funds, and set auto-reload from the Dart Charge mobile app on iOS and Android.
You have 28 days after crossing to pay. After that, a £70 penalty is automatically issued — no reminders, no warnings. Pay or set up an account before you cross.
Dart-Tag account holders pay £1.90 per crossing instead of the full £2.50. The account is free — the discount pays for itself after just a few crossings.
If the crossing is closed or you wish to avoid the charge, the Blackwall Tunnel (A102) is free and connects Greenwich to Poplar. Allow extra time — it is often congested.
