Is it permissible to use the shoulder lane for passing vehicles?

Using the shoulder lane for passing vehicles is not permitted under normal driving conditions. The shoulder is designed for emergency use, providing a safe area for vehicles to pull over in case of breakdowns or other emergencies. Utilizing the shoulder for passing can create hazardous situations, as it may not only endanger the moving vehicle but also cause confusion or danger for other drivers who may not expect to see vehicles traveling there.

While some options may suggest limited circumstances under which using the shoulder for passing might be acceptable, such as during emergencies or when signaling, the fundamental rule is that the shoulder should be kept clear for its intended use. This ensures that all drivers can operate their vehicles safely and predictably. Thus, the reason that this approach is clear-cut is to maintain road safety and the proper function of traffic laws.
