What should riders of motorcycles be particularly cautious about when near intersections?

Answer: C — Automobiles failing to yield

Riders of motorcycles should be particularly cautious about automobiles failing to yield at intersections because these locations represent a high-risk area for collisions. Intersections require both motorcyclists and drivers to be alert, as they are places where vehicles change lanes, make turns, or come to a stop. Many accidents occur when drivers do not see motorcycles or fail to give them the right of way, leading to potentially severe consequences for motorcycle riders, who are more vulnerable than those in larger vehicles. It's essential for motorcycle riders to be aware of their surroundings and anticipate that vehicles may not always yield as expected. This awareness allows them to take necessary precautions, such as adjusting speed or positioning themselves for better visibility. By being extra cautious at intersections, riders can enhance their safety and reduce the risk of accidents.
