Understanding barrier-free tolling on Dublin's busiest motorway
The M50 uses a modern barrier-free tolling system, meaning you never need to stop or slow down to pay a toll. Instead, sophisticated camera technology captures your vehicle details as you pass through the designated toll point. This system has been operational since 2008 and processes millions of transactions annually.

There is only one toll point on the M50, located between Junction 6 (N3 Blanchardstown) and Junction 7 (N4 Lucan). This section is often referred to as the West-Link, named after the original toll bridge that operated here before the barrier-free system was introduced.
The toll point spans all lanes of the motorway in both directions. Large overhead gantries contain the cameras and sensors that capture passing vehicles. You will see blue signs indicating the toll point as you approach.
You only pay the toll once per journey through this point, regardless of how many junctions you use on the M50. If you do not pass between Junction 6 and Junction 7, you do not incur a toll charge.

The M50 uses Automatic Number Plate Recognition (ANPR) combined with electronic tag detection
As you approach the toll point, sensors detect your vehicle entering the tolling zone. Classification sensors determine your vehicle type based on height and number of axles.
If you have an eFlow tag, the system reads it electronically. Simultaneously, high-resolution ANPR cameras photograph your front and rear registration plates for verification or video account billing.
The system matches your tag ID or registration number against the eFlow database. Tag and video account holders are identified and billed automatically to their accounts.
Registered users have the toll automatically charged. Unregistered vehicles have until 8pm the following day to pay via the eFlow website, app, or at retail outlets.

Always ask your rental company about their toll policy when collecting the vehicle. This avoids unexpected charges or penalties later.
