Final answer:
Passing is prohibited when the vehicle you are following has a slow-moving vehicle symbol or when you would be required to pass to the right of a left-turning vehicle.
Step-by-step explanation:
Passing is prohibited when:
- The vehicle you are following has a slow-moving vehicle symbol.
- You would be required to pass to the right of a left-turning vehicle.
When you see a vehicle with a slow-moving vehicle symbol, it indicates that the vehicle is moving at a significantly slower speed compared to the normal flow of traffic. In such situations, it is prohibited to pass the slow-moving vehicle as it might be unsafe and can lead to accidents.
Similarly, when you are driving behind a vehicle that is preparing to turn left, and you need to pass that vehicle, it is also prohibited. Passing to the right of a left-turning vehicle can be dangerous and can cause collisions with oncoming traffic.
