Question

Where in ireland can you report an unsafe hgv to and if you have the phone number or address thanks

Answer 1

How is it unsafe?

Most HGV's have one of those "How's my driving?" stickers on the back with a number to call to say if they are driving like a mental.

If however, the vehicle is unsafe through MOT or lack of insurance then I'd ring the Police direct and give the name of the HGV company as well as the license plate details.  

Answer 2

Just phone the police.
