II. Sharing the road
Sharing the road with farm machinery

Farm machinery moves quite slowly compared to other road users. Most tractors and combines have a maximum speed of 40 km/h, but travel at less than 40 km/h when towing implements or wagons. Farm machinery is often oversized, wide or long or both, making it difficult for the driver to see vehicles coming up from behind. Farmers often turn directly into fields rather than roads or lanes, or move from lane to lane. Remember that it is common for farmers to be on the roads after dark during peak planting and harvesting seasons.

Farm machinery on the road must display an orange and red slow-moving vehicle sign on the rear of the vehicle. The sign warns other drivers that the vehicle is travelling at 40 km/h or less. If you see one of these signs, slow down and be cautious. Stay well back and do not pass until it is safe to do so. (See the slow-moving vehicle sign here.)
