Why is it an offence to drive along the road shoulder of an expressway?

Driving along the road shoulder of an expressway is considered an offence primarily because it may lead to an accident. The road shoulder is designed as a safety feature, intended for emergency situations where a vehicle needs to stop or pull aside, and not for regular travel. When a driver uses the shoulder for overtaking or as an alternative lane, it poses serious risks not only to themselves but also to other road users. This can result in collisions, as drivers on the expressway do not expect vehicles to be traveling on the shoulder, which can lead to hazardous situations.

The other choices, while they may have some merit, do not encapsulate the critical danger that such an action represents. Confusion and potential traffic jams could occur, as could frustration among drivers, but the foremost concern is the increased likelihood of accidents that can cause harm to individuals and disrupt the flow of traffic significantly.
