Why do most collisions happen at curves?

• A. They require more careful braking
• B. Because visibility is limited at night
• C. Inexperienced drivers are common near curves
• D. People go through them too fast

Answer: (D)

Curves demand you adapt speed to keep the car on the intended path. Negotiating a turn relies on tire grip to provide the sideways (centripetal) force needed to change direction. The faster you go, the more sideways force is required. If your speed exceeds what the tires can safely supply, you start to lose control—the car can slide outward, drift toward the lane edge, or even cross into oncoming traffic or off the road. Because the danger in a curve comes from not slowing enough to match the curve’s demands, going through curves too fast is the main reason collisions happen there.
