Saving Money on Tolls

01

Get a Tag Account for Regular Use

If you use the M50 more than once or twice a month, a tag account is the smartest choice. You will pay €2.60 per journey instead of €3.80 as an unregistered user - that is a saving of €1.20 every single trip.

For a daily commuter making two journeys per day, five days a week, that adds up to €624 saved per year. The tag is free when you open an account, and you can manage everything online.

Video Account for Occasional Drivers

Do not use the M50 often enough to justify a tag? A video account is the next best option. You register your vehicle online, and the toll is automatically charged when the cameras capture your registration.

At €3.20 per trip, you save €0.60 compared to paying as an unregistered user, and you never have to remember to make a payment. Perfect for visitors to Dublin or those who only occasionally travel through the toll point.

Set Payment Reminders

If you do travel as an unregistered user, the payment deadline is 8pm the day after your journey. Missing this deadline triggers an immediate €4 penalty, which can quickly escalate to much larger amounts.

Our advice: set a calendar reminder or phone alarm for 7pm the following day. This gives you an hour buffer to make your payment before penalties apply. Better yet, pay immediately after your journey while it is fresh in your mind.

04

Keep Payment Receipts

When you make a payment, always save the confirmation email or take a screenshot of the receipt. In the rare event of a dispute or system error, having proof of payment can save you significant time and hassle.

Tag and video account holders can access their full journey history through the eFlow website or app, making it easy to track expenses and verify payments.

Ensuring Smooth Toll Processing

05

Keep Your Registration Plate Clean

The M50's ANPR cameras need to clearly read your registration plate to process your toll correctly. A dirty, damaged, or obscured plate could result in failed recognition, which may lead to payment complications or penalties.

Regularly check that your plates are clean and legible, especially during winter months when road salt and grime can build up quickly. This simple habit prevents unnecessary issues.

06

Position Your Tag Correctly

If you have an eFlow tag, ensure it is mounted correctly on your windscreen. The tag should be positioned behind the rearview mirror, in the clear area of glass without any tinting or heating elements.

Check that the tag is firmly attached and not blocked by any objects like dash cameras or parking permits. A properly positioned tag ensures reliable detection every time you pass through a toll point.

07

Update Your Details Promptly

Changed address? Got a new vehicle? Updated your payment card? Make sure your eFlow account reflects these changes immediately. Outdated information can lead to missed correspondence, failed payments, and potential penalties.

Log in to your account regularly to verify that all your details are current, especially your email address and registered vehicles.

08

Check Your Account Balance

If you use a prepaid tag account, monitor your balance to ensure you always have sufficient credit. You can set up automatic top-ups or low-balance alerts to prevent your account from running empty.

A tag with zero balance will not provide the discounted rate - the system will treat you as an unregistered user and charge the higher rate.

Advice for Tourists & Rental Cars

09

Ask Your Rental Company

Before leaving the rental desk, ask specifically how toll payments are handled. Some rental companies include a toll tag in the vehicle and add charges to your final bill. Others expect you to pay tolls yourself.

Understanding the arrangement upfront helps you avoid surprise charges or penalties. If you need to self-pay, ask the company for the vehicle registration number - you will need it to make a payment.

10

Foreign-Registered Vehicles

If you are driving a UK or other foreign-registered vehicle, be aware that the system may take longer to process your registration. The cameras will capture your plate, but linking it to your details for billing purposes can be more complex.

The safest approach is to proactively pay your toll at eflow.ie using your registration number, rather than waiting to be billed. This ensures you avoid any potential penalty situations.

11

Beware of Scams

Unfortunately, toll-related scams do exist. Be wary of unsolicited emails, texts, or calls claiming to be from eFlow and demanding immediate payment. Legitimate eFlow communications will never ask for payment via unusual methods.

Always access your account through the official eFlow website by typing the address directly into your browser. If in doubt, call eFlow customer service on 0818 50 10 50 to verify any correspondence.

12

Plan Your Route

Remember that you only pay the toll if you pass between Junction 6 and Junction 7. If your journey does not require this section, you can use the rest of the M50 toll-free.

However, attempting to exit and re-enter the motorway solely to avoid the toll is rarely practical and may add significant time to your journey. In most cases, paying the toll is the most efficient option.

Navigating the M50 Safely

The M50 is one of the busiest roads in Ireland, carrying over 140,000 vehicles daily. During peak hours, congestion is common, particularly around major interchanges. Here are some tips for a smoother journey:

  • Avoid peak hours if possible: Traffic is heaviest between 7:30-9:30am and 4:30-7:00pm on weekdays. If your schedule is flexible, travelling outside these times can significantly reduce journey time.
  • Stay informed: Check traffic conditions before you travel using services like AA Roadwatch or Google Maps live traffic. The M50 has variable message signs that display current conditions.
  • Use the correct lane: Keep to the left unless overtaking. The M50 has multiple lanes, and lane discipline helps traffic flow smoothly.
  • Maintain safe distances: Heavy traffic requires extra attention. Keep a safe braking distance from the vehicle ahead, especially in wet conditions.
  • Know your junction: The M50 junctions are numbered. Familiarise yourself with your entry and exit junctions before you travel to avoid last-minute lane changes.
