What should you never do on the traveled part of the roadway?

The reasoning behind the choice of never stopping on the traveled part of the roadway is rooted in the principles of road safety and traffic flow. Stopping in such areas can create hazards for both the driver and other road users. It can lead to traffic congestion, increase the risk of rear-end collisions from vehicles not expecting a sudden stop, and put the driver in a vulnerable position, especially on busy roads.

Additionally, when a vehicle stops unexpectedly on the traveled portion, it can obstruct the flow of traffic, causing frustration for other drivers and possibly leading to dangerous maneuvers as motorists attempt to navigate around the stopped vehicle. Stopping is typically reserved for designated areas, such as traffic signals, stop signs, or emergency situations where it is necessary for safety, rather than on the main traveled part of roadways where constant movement is expected.

In contrast, yielding to pedestrians, while always important, is a necessary action that enhances safety. Changing lanes frequently can lead to unpredictable driving patterns, and while using a cellphone is heavily discouraged, the context doesn't compare to the significant threat posed by stopping in the traveled part of the roadway. Thus, the emphasis on never stopping aligns with maintaining the integrity of traffic flow and overall roadway safety.
