1. Weather

Weather refers to the atmospheric conditions at a specific time and place—like temperature, wind, rain, snow, fog, and sunshine. When it comes to driving, weather has a huge impact on visibility, traction, and overall safety.

  • Rain: Reduces visibility, Makes roads slippery, especially at the start of a rainstorm and increases risk of hydroplaning.
  • Snow and Ice: Causes very low traction. Increases stopping distances. Can cover road markings or signs. May require snow tires or chains.
  • Fog: Severely limits visibility. Makes it hard to judge distance and speed. Calls for low-beam headlights and slow driving.
  • Wind: Can blow vehicles, especially high-sided ones, off course. May move debris or dust into the road.
  • Extreme Heat: Can cause tire blowouts, engine overheating, and battery drain. Also increases driver fatigue.
  • Hail or Freezing Rain: Damages the vehicle. Creates a thin layer of invisible ice (black ice) that's extremely dangerous.
