Who has the greatest accident potential on the roadway?

The option indicating bicyclists and pedestrians as having the greatest accident potential on the roadway is correct because these individuals are inherently more vulnerable compared to others. Bicyclists and pedestrians lack the protective structure of a vehicle, making them more susceptible to serious injury in the event of a collision. Their smaller size and presence on the road can also contribute to accidents, especially in areas where they share space with larger vehicles.

While motorists, taxi drivers, and commercial truck drivers are all involved in roadway incidents, they typically benefit from vehicle safety features that shield them from injury to some extent. Bicyclists and pedestrians, on the other hand, face considerable risks, particularly in busy traffic areas where visibility is lower and interactions with vehicles are more frequent. The combination of these factors contributes to a higher accident potential for bicyclists and pedestrians on the roadway.
