Vehicle Condition and Load

🔧 Vehicle Condition

  • If your tires are worn, brakes are weak, or your car has mechanical issues, drive slower and more cautiously.
  • These problems can affect stopping distance, traction, and control — so compensate with more space and lower speed.
  • Best practice: Keep your vehicle well-maintained so it’s ready when you need it most.

🛻 Heavy Loads or Towing

  • Carrying heavy cargo or towing a trailer means:
    • Slower acceleration
    • Longer stopping distances
  • Drive with extra caution, maintain moderate speeds, and plan farther ahead for stops and turns.
