Drive Defensively

Following are some tips from the National Safety Council’s Defensive Driving Course. This list is not meant to be all encompassing and a particular precaution may not be effective in all circumstances.

Preventing Collisions:

  • Recognize the hazards: Continuously scan the road ahead and behind checking you mirror every 3-5 seconds.
  • Understand the defense: Play the “what if” game by thinking “what if” the driver in front of me stops suddenly? “What if” someone runs a red light at the next intersection? “What if” that driver in the oncoming lane swerves into my lane?
  • Act correctly in time: Think ahead, try to anticipate what other drivers around you might do, avoid hazardous or dangerous situations before it’s too late.
  • Help avoid collisions through proper vehicle maintenance. Remember, from clean windows to properly adjusted mirrors to regular engine servicing amuch more, you can be held responsible for the little, as well as the big defects in your car.
