A CRFI reading of 0.82 indicates which level of braking coefficient?

• A. Low braking coefficient
• B. Medium braking coefficient
• C. High braking coefficient
• D. Very high braking coefficient

Answer: (C)

The CRFI reading reflects the friction between tires and the road, with higher numbers meaning more grip and a higher braking coefficient. A value of 0.82 indicates very good traction on the surface, and within this classification scheme that level of grip is described as a high braking coefficient. In practical terms, that means braking performance would be strong, with relatively shorter stopping distances and good stability during braking. The other levels correspond to progressively less friction, so they don’t fit for such a high reading, and this scale places 0.82 in the high category rather than a lower or different category.
