Moving livestock on public roads
If you own livestock and are moving them around, you don't have to put up signs. However, as a stock owner you do have a duty of care under common law and the Civil Liability Act 1936 to warn others of potential dangers.
Using signs is a good way to let drivers know about the animals you're moving on a road. The signs aren't a legal requirement for drivers to be careful, and they don't fully protect the livestock owner in case of an accident, but they are intended to warn drivers that there may be stock on the road so they can be cautious.
The Stock on Roads Operational Induction provides a uniform approach for the use of both temporary and permanent stock warning signs on roads under the care and control of Department for Infrastructure and Transport (DIT).
