Introduction (the basic idea) - Skid resistance is a force developed when a tire that is prevented from rotating slides along the pavement surface. Skid resistance is an important pavement evaluation parameter because:- Inadequate skid resistance will lead to skid related accidents
- Skid resistance measurements can be used to evaluate various types of materials and construction practices
- Most agencies have a responsibility to provide users with a roadway that is "reasonable" safe.
Visualize this: Situation 1
While you were driving your car at 60 km/hr during heavy rain and suddenly in front of you there is a car coming to a halt because there is an accident, what do you do? You push the brake abruptly and you heard sketching sound of your car and your car start to skid without stopping straight away.
Visualize this: Situation 2
when you are negotiating a sharp bend at a speed of 50 km/hr on a slippery road, do you suddenly feel your car is skidding along the road and you want to step on the brake quickly to avoid going of the bend? These are some of the real life scenario that warrants us as a driver to be extra careful whenever we drive on a wet condition road surface.

Those sketching sounds when you brake abruptly and tire marks on road surface especially at junction, roundabout, traffic intersection, and others, which needs us to constantly brake to slow down our car are called "skid resistance".
