Under what circumstance must you never drive on the left side of the road?

Driving on the left side of the road is prohibited in certain situations to ensure the safety of all road users. When there are two or more traffic lanes in each direction, the left side is usually reserved for specific purposes, such as allowing overtaking or accommodating different road rules that apply in that area.

Fundamentally, driving against the flow of traffic in multi-lane situations can lead to head-on collisions, which are often severe. The traffic rules are designed to maintain order and predictability on the road; drivers may have an expectation that vehicles in their lane will be traveling in the same direction. Therefore, it is crucial to remain in the correct lane and adhere to traffic laws to promote safety and avoid chaos on the roads.

In contrast, the other situations listed, while they may involve caution or specific actions, do not universally prohibit driving on the left side of the road.
