What rule must bicycles follow?

Bicycles are considered vehicles under Pennsylvania law, which means they must adhere to the same traffic rules and regulations that apply to motor vehicles. This ensures safety for all road users, including motorists, cyclists, and pedestrians. By following the same rules as cars—such as obeying stop signs, traffic signals, and yielding when required—cyclists can help maintain order on the road and reduce the risk of accidents.

In contrast, ignoring traffic signals would create confusion and potentially dangerous situations. While there might be allowances for riding on sidewalks in certain areas, it is not a blanket rule and can vary by municipality. Bike lanes exist for the convenience and safety of cyclists, but they are not the exclusive path for bike travel; cyclists can ride on public roadways as long as they follow traffic laws. Thus, the requirement for bicycles to follow the same traffic rules as cars is critical for their integration into the broader traffic system.
