Factors Affecting Driver Abilities | Road Safety

Road safety largely depends on the driver’s physical and mental condition. Various factors can negatively affect their abilities and increase the risk of accidents. 🚨

😴 1. Fatigue and Sleepiness

  • ⚠️ Reduced concentration and attention.
  • 🧍‍♂️ Slower movements and less precision.
  • 🚗 Increased reaction time and hostile behavior.
