Where are bicyclists allowed to ride?

Bicyclists are allowed to ride on the roadway, on the shoulder, or in a bicycle lane, which follows the principles of safe and effective bicycle travel. Riding on the roadway ensures that cyclists are visible to motor vehicle operators and can navigate traffic safely. Bicyclists often make use of shoulders, which provide additional space away from passing vehicles, enhancing safety. Bicycle lanes are specifically designated areas on the roadway that are intended for the exclusive use of bicyclists, providing a defined path that keeps them separate from vehicle traffic, reducing the risk of accidents.

In contrast, riding on freeways is generally restricted, making it illegal in many locations, including where no signs permit it. Using left turn only lanes without turning is not a safe practice for cyclists, as these lanes are designed for vehicles ready to make a turn. Sidewalk riding can be regulated differently based on local laws and conditions, often prohibiting cyclists from using sidewalks in business districts or on certain streets to avoid pedestrian conflicts. Therefore, the safest and most legally compliant areas for bicyclists to ride are those outlined in the correct answer, emphasizing roadway, shoulder, and bicycle lane use.
