What is the primary rule regarding lane use on the roads?

The primary rule regarding lane use on roads in Belgium and many other countries is that drivers must drive in the right lane. This rule is crucial for maintaining order on the road and ensuring that traffic flows smoothly. The right lane is typically designated for general vehicle use, while other lanes may serve specific functions, such as passing or accommodating larger vehicles.

This regulation is designed to establish a consistent system that promotes safety and efficiency during travel. It minimizes confusion among drivers about where they should be positioned on the road, especially in multi-lane environments. By driving in the right lane, drivers contribute to reducing the likelihood of collisions and improve overall road safety.

In contrast, being able to choose any lane arbitrarily would lead to potential hazards and disrupt the flow of traffic. Similarly, the idea of only being able to drive in the left lane contradicts the established norms for road usage. The option of using only bus lanes is limited and specifically designated for public transport vehicles, therefore not applicable for regular drivers.
