What is correct in this situation?

In the given scenario, the rules indicate that you must reduce your speed when approaching a truck at an intersection, as trucks often have difficulty maneuvering. Additionally, the truck is signaling to make a turn, which means it has the right of way.

Understanding these rules is crucial for maintaining safety on the road. Reducing speed allows you to assess the situation better and react appropriately. The right of way ensures that larger vehicles, which require more space and time to navigate, can do so without hindrance. Therefore, both actions support safe driving in such circumstances.
