Average speed cameras in Ireland: What drivers need to know

September 2025

Average speed cameras have been in use in Ireland since 2017 in Dublin’s Port Tunnel, but they didn’t appear on other roads until 2022. Following an initial trial, they were installed on the M7, spanning from Junction 26 (Nenagh West) to Junction 27 (Birdhill), operating in both directions.   

Now, these cameras are also operational on the N2 (between Cullen and Ballymagarvey in Co. Meath), the N3 (between Kilduff and Billis in Co. Cavan) and the N5 roads (between Lislackagh and Cuilmore in Swinford, Co. Mayo).  

The pilot program for these cameras began in early 2021 but faced several postponements. Calibration and certification delays were cited as primary reasons for the schedule adjustments.

These cameras measure vehicle speeds over a set distance rather than at a single point. This method prevents drivers from slowing only when approaching a camera, promoting a steadier traffic flow. A 2016 UK study indicated a 36% decrease in severe and fatal accidents following the installation of such cameras.  

Average speed cameras were first introduced in Dublin’s Port Tunnel in 2017. Before their installation, over half of the vehicles exceeded the 80 km/h speed limit, with 20% surpassing it by more than 10 km/h. This figure dropped dramatically to 0.15% post-installation.  

Average speed cameras use Automatic Number Plate Recognition (ANPR) technology to record the time, date, and location of each vehicle that passes through. If a vehicle reaches the next camera too quickly, this information is processed for enforcement, indicating a potential speeding violation.

These cameras are considered effective in enforcing speed limits, reducing overall travel times, and minimising traffic disruptions caused by conventional speed enforcement methods. Additionally, smoother traffic flow reduces fuel consumption particulate matter and noise emissions. These cameras can’t really be tricked which makes them very effective in slowing down those prone to breaking the speed limit.

Penalties for speeding drivers caught exceeding speed limits by these cameras face fines of up to €160 and can accrue three penalty points on their license. If you fail to pay the fine within the stipulated 28 days, it increases to €240. You'll be summoned to court if you don't pay this fine within 56 days from the original notification date, and if convicted, you could receive up to 5 penalty points. There is a third payment option as well, where you can avoid going to court by paying €320, twice the sum of the original fine, no later than 7 days before the court date.  

If you’re a learner or novice driver, understanding road signs in Ireland is essential for staying safe and avoiding fines. Our blog breaks it all down, and with Allianz car insurance tailored for young drivers, you can feel confident every time you’re on the road.

As of now, average speed cameras are in Dublin’s Port Tunnel, on the M7, N2, N3, and N5 roads.

The primary objective of installing average speed camera is to prevent death and serious injury on Irish roads.

If detected, you will get a notice of your fine and penalty points for the offence by post.
