What does Static traction refer to?

Static traction refers to the condition of having no movement between the tires and the road surface. This occurs when a vehicle is at rest, and the tires are not spinning or sliding. In this state, the frictional force between the tires and the road is at its maximum, providing optimal grip. This ensures that the vehicle can remain stationary without sliding.

In driving terms, understanding static traction is crucial for scenarios such as starting from a stop or navigating on steep inclines. The ability of tires to grip the surface effectively allows for controlled acceleration without losing traction. The other options describe concepts that do not accurately reflect the nature of static traction, which is characterized specifically by the absence of movement.
