# Explanation
When overtaking animal-drawn vehicles outside built-up areas, the law establishes a minimum lateral distance of **1.5 meters** as a safety measure. This separation is mandatory to avoid scaring the animal and to prevent accidents. The distance must be at least 1.5 meters, although in special cases it could be greater depending on road circumstances.
