Which item is NOT recommended to improve visibility to other traffic?

Using only rearview mirrors is not recommended for improving visibility to other traffic because relying solely on them limits your awareness of the surroundings. Mirrors offer a view of what's behind you, but they do not provide information about vehicles or obstacles that might be approaching from the sides or front. To enhance visibility and safety, it's essential to maintain a broad awareness of the entire environment while riding. This includes actively checking blind spots and using all available visual cues, not just what is visible in rearview mirrors.

In contrast, wearing bright colored gear, driving with headlights on, and using flashing brake lights are effective strategies to make a motorcycle more visible to other drivers. Bright colored gear can catch the attention of other road users, ensuring that motorcyclists stand out against the background. Riding with headlights on increases visibility during the day and night, making it easier for other vehicles to spot motorcyclists. Flashing brake lights when stopped signal to vehicles behind the motorcyclist, alerting them to a potential stop, which can help prevent rear-end collisions.
