Step-by-step explanation:
When practical, it is best to have at least 15 feet on both sides of your vehicle.
This recommendation is based on research and accounts for the width and depth required for safe maneuvering and potential hazards.
An older rule of thumb suggested 5 feet side-to-side and 7-8 feet deep, but newer work suggests 8 diameters side-to-side and 15 diameters deep, ensuring a better margin of safety.
