‘Give Way to Stock’ signs are typically displayed 300m before a livestock crossing, but this can vary. When you see one, you must slow down and allow the animals to cross before continuing on your way.
When a stop sign is displayed at a stock crossing, you need to come to a complete halt and not start driving again until all the animals have completed their crossing.
Both of these stock-related road signs are legally enforceable, so make sure you abide by them or you may receive a fine.
For more information, refer to rules 402, 403 and 404 of Victorian Road Safety Road Rules 2017.
