If you want to reduce the risk:
Select Ireland, Road Safety & Speed camera's,
Get the right file for your satnav,
I have a Garmin & Garmin upload worked for me.
This is a Custom POI, fiddle with POI settings to suit.
I did it last week, But as I usually only travel on motorways I have not passed one of these mobile zones yet. so I am unsure how effective it is.
This POI is free of charge, other companies charge €27 or €29 for a similar POI list.
One of my Garmin satnav's also displays the current speed limit, and my current speed, a very handy feature.
I have a GPS tracker in my car so I always have a log of what speed I was doing in an area If I wanted to dispute anything. Some satnavs will keep a log too.
