The short answer to this question is: pedestrians, cyclists, and motorcyclists are the most vulnerable roadway users.

This is because these roadway users are not as protected as occupants of cars and other motor vehicles. Pedestrians, cyclists, and motorcyclists have a greater exposure to dangers while out and about on the roads. A car provides some physical protection if there is an accident, however pedestrians, cyclists, and motorcyclists have no such protection.

In the United States, more than 60,000 pedestrians, cyclists, and motorcyclists are killed each year in traffic accidents. According to the Centers for Disease Control and Prevention, these three groups of roadway users account for the majority of traffic fatalities.

While laws can help protect these vulnerable roadway users, the responsibility ultimately falls on motorists to be extra cautious when driving. Motorists should be aware of how their driving can affect pedestrians, cyclists, and motorcyclists. They should slow down and be extra careful when turning, as this is when many accidents occur.

Motorists should also be especially cautious in areas known to have a higher concentration of pedestrians, cyclists, and motorcyclists. These include school zones, parks, and residential areas. Motorists should be especially prepared for hidden dangers such as sudden turns or unexpected lane changes.

Finally, motorists should observe all speed limits and use extra caution when needed. This will ensure that all roadway users are safe regardless of whether they are in cars, walking, biking, or riding a motorcycle.

In conclusion, pedestrians, cyclists, and motorcyclists are the most vulnerable roadway users. To ensure their safety, motorists should be extra careful when driving and be prepared for hidden dangers. This will ensure that all roadway users can safely use the roads.
