Final answer:
When large vehicles make turns, they need more space and have significant blind spots, requiring caution from other drivers. Their larger size and momentum also mean they take longer to stop, making their turns less predictable, especially at higher speeds.
Step-by-step explanation:
Be cautious when large trucks, buses, and vehicles with trailers make turns because they require more space to maneuver and may swing wide or encroach into adjacent lanes. These vehicles have significant blind spots, and their size and weight require extra time and distance to stop or change direction compared to smaller vehicles. Therefore, their turns can be unpredictable, especially if a driver is speeding through the intersection and does not anticipate the extended space and time needed for these large vehicles to complete a safe turn.
