If a bicyclist has a red or orange pennant flag attached to their bike, what does it symbolize?

The presence of a red or orange pennant flag attached to a bicyclist's bike is typically a safety measure that signifies that the rider may have impaired hearing. This visual alert serves to notify motorists and other cyclists of the potential communication challenges, allowing for greater awareness and caution while passing or interacting with the rider. Such flags are important for ensuring the safety of all road users.

Choosing this interpretation helps underscore the necessity of visual aids as a means of communication for cyclists who may not hear approaching vehicles. Flags like these enhance visibility and signify to others on the road to be mindful of the interaction, acknowledging the unique needs of the rider.
