Should slow vehicles use the right-hand lane except when passing or making a left turn?

The statement that slow vehicles should use the right-hand lane except when passing or making a left turn is grounded in safety and traffic flow principles. Using the right-hand lane allows faster-moving vehicles to pass more easily on the left, reducing potential hazards and maintaining a smooth flow of traffic. This practice helps in minimizing the likelihood of collisions and ensures that slower vehicles do not obstruct the speed of other drivers who may need to travel at higher speeds.

By encouraging slow vehicles to stick to the right, it creates a predictable driving environment where everyone knows where to expect slower traffic, thereby facilitating a safer and more efficient road experience. This guideline is applicable not only on highways but generally in various road situations to enhance overall traffic management.
