What does a red and orange sign displayed by farm machinery on the road indicate?
- The machinery is carrying dangerous goods
- The machinery is large and needs more space to turn
- The machinery is a slow-moving vehicle ✓
- The machinery is heading to a farm
Answer: C. The machinery is a slow-moving vehicle
A red and orange sign on farm machinery means the machinery is a slow-moving vehicle.
Why this is the answer
The handbook describes the slow-moving vehicle sign as an orange triangle with a red border. It tells drivers that the vehicle will be moving at 40 km/h or less. Farm tractors, implements and machinery that cannot keep speeds above 40 km/h must display it on the road. That is why the sign points to a slow-moving vehicle: you should recognize it as a warning to watch for a vehicle moving well below normal traffic speed and adjust your speed.
Why the other answers are wrong
- A. The machinery is carrying dangerous goods — The sign does not indicate that the machinery is carrying dangerous goods; it marks a vehicle that travels slowly.
- B. The machinery is large and needs more space to turn — The machinery may be oversized, but the sign itself is about low speed, not about needing extra room to turn.
- D. The machinery is heading to a farm — The sign does not tell you where the machinery is going; it only marks a vehicle that travels slowly.
Remember it
Red border, orange triangle: think slow tractor ahead and be ready to reduce speed.
