What is the most important rule of the road in South Africa?

Keeping to the left side of the road as far as is safe is crucial in South Africa because the country follows a left-hand traffic system. This means that vehicles drive on the left side of the road, with the steering wheel on the right side of the vehicle. Adhering to this rule is essential for maintaining order and safety on the roads. It helps prevent head-on collisions and ensures that other road users, including pedestrians and cyclists, can navigate traffic safely.

This guideline also supports the flow of traffic, as vehicles are more likely to stay in their designated lanes when they consistently adhere to driving on the left. Motorists who keep to the left assist overtaking vehicles, which generally pass on the right, thereby facilitating smoother and more predictable traffic movement. Consequently, this rule is foundational to safe driving and is a primary aspect of road law in South Africa.
