Why must motorcycles be cautious when approaching an intersection?

Answer: A — They are smaller and less visible

Motorcycles must be cautious when approaching an intersection primarily because they are smaller and less visible compared to cars and trucks. This smaller size can make it difficult for other drivers to see them, especially in situations where visibility is reduced, such as during poor weather or when there are obstructions like parked vehicles. Due to this reduced visibility, drivers of larger vehicles may not notice motorcycles in traffic, leading to potential collisions. Moreover, when motorcycles approach intersections, they must also consider the actions of other vehicles that might not be fully aware of their presence. The common tendency for car drivers is to look for other cars, potentially overlooking motorcycles. Therefore, being cautious and alert is crucial for motorcyclists to navigate intersections safely, ensuring they can react appropriately to other traffic and avoid accidents.
