What to Do After a Breakdown on Dublin's M50

Immediate actions (M50 safety checklist)

1. Indicate early and move onto the hard shoulder as soon as it is safe.
2. Stop as far left as possible, keep wheels turned away from traffic, and switch on hazard lights.
3. Exit via the passenger side and wait behind the barrier (never on the live lane).
4. Do not attempt repairs on the hard shoulder. High-speed traffic makes it unsafe.

Use a roadside emergency phone if available, or call the Motorway Traffic Control Centre on 0818 715 100. They can coordinate recovery and Garda assistance when required.

What NOT to do

• Do not stand beside the vehicle on the hard shoulder.
• Do not try to push the car on the M50.
• Do not place yourself in live traffic lanes to set up triangles.

Arranging a tow on the M50

Once safe, contact a towing service. M50 response times are often quick, but peak-hour congestion can slow down access. To estimate how long you might wait, read our guide on towing arrival times in Dublin.

What to tell the tow operator

• Your location: nearest junction number, direction of travel, and any overhead signage.
• Vehicle details: registration plate, make/model, and whether it’s a car or van.
• Situation: can it roll, is it in a safe spot, any flat tyre or visible damage.
• Destination: garage name/address (or your preferred drop-off point).

Ensure you have the necessary paperwork. If you're unsure, check the list of documents needed for towing in Ireland.

Why you should know this

Quick, correct actions reduce the risk of secondary accidents and keep traffic flowing. Understanding the process also minimises stress during an already tense moment.

Practical tips

• Keep a high‑vis vest and warning triangle in the car—it's a legal requirement for emergencies.
• Store emergency numbers in your phone, including your insurer and a local tow company.
• Stay behind the barrier until help arrives; the hard shoulder is not a safe waiting area.
