Farmers using quad-bikes must wear helmets and undergo safety training from today.
The new quad-bike law is one of the first of its kind in Europe.
It comes as the Heath and Safety Authority launches a campaign encouraging farmers to think about their health and wellbeing on the farm.
HSA Senior Inspector for farm safety, Pat Griffin says farmers are at increased risk of stress, mental health issues, and heart disease:
"If you've got poor health, you generally have some sort of disability. If you've got a musculoskeletal injury, you may have a back injury or a shoulder injury. Operating machinery and looking after livestock with such injuries can be very very difficult, and can actually lead to further injury and accidents on the farm".
