Which factor among these can contribute to a skid?

• A. wheel load, tread depth, and brake pressure
• B. traction, wheel load, and force of motion
• C. force of motion, brake pressure, and tire inflation
• D. tread depth, traction, and inflation

Answer: (B)

Skids happen when tires lose grip with the road, so the factors that directly affect that grip, the weight on the tires, and how fast you’re moving are the ones that matter most. Traction is the level of grip between the tire and the surface; if the road is wet, icy, or the tires are worn, traction is reduced and skidding is more likely. Wheel load—the weight the tires carry—influences the normal force and thus the available friction; more load can make it harder to maintain control if you brake or steer abruptly, especially when traction is limited. The force of motion, basically your speed and momentum, matters because higher speed makes it harder to stop or steer in time when grip is compromised, increasing skid risk. The other factors listed can affect grip in related ways, but they don’t capture the primary drivers as directly. Brake pressure is crucial during braking on low-traction surfaces, but skids are most influenced by traction, weight on the tires, and motion. Tread depth and tire inflation affect grip too, but the combination of traction, wheel load, and motion best explains when a skid is likely to occur.
