Defensive driving means anticipating hazards instead of just reacting to them. Know your own limits and your vehicle's, take responsibility for your actions, and keep an eye on 'the other guy.' The SIPDE process gives you a routine for doing it.

What shapes a driver's attitude:

  • Demographics: age, sex, employment, education, where you live
  • Personality: tolerance, aggressiveness, risk taking, peer pressure
  • Development: physical, emotional, social, behavioral
  • Environment: community, entertainment, parents, peers, partner
  • Driving environment: daylight or dark, weather, road, vehicle, passengers
  • Driving ability: knowledge, skill, experience

National Safety Council guidelines:

  • Secure every passenger, including children and pets, before starting the engine
  • Lock all doors
  • Driving too fast or too slow both increase the chance of a collision
  • Plan to drink? Designate a sober driver; alcohol is a factor in almost half of fatal crashes
  • Avoid an impaired driver by turning right at the nearest corner or exiting at the nearest exit
  • If an oncoming car crosses into your lane, pull over, sound the horn and flash your lights
  • Report suspicious or reckless drivers to police immediately
  • Don't contest the right-of-way or race another car during a merge
Handbook p. 59 ↗

Signs a driver may be impaired:

  • Straddling the center line
  • Weaving
  • Making wide turns
  • Stopping abruptly
  • Responding slowly to traffic signals
Handbook p. 59 ↗

Four traits of a defensive driver:

  • Alertness: well rested and never impaired
  • Anticipation: keeps a safe following distance and expects problems
  • Judgment: obeys limits, slows in bad weather, never tries to beat lights or trains
  • Skill: aware of others' blind spots, scans ahead, avoids distraction
Handbook p. 60 ↗

Know the rule

Defensive driving also saves fuel, lowers insurance premiums and lengthens the life of your vehicle.

Handbook p. 60 ↗

Put it into practice

The car ahead is weaving and stopping abruptly for no reason. The driver may be impaired. Drop back, turn right at the next corner (or take the next exit) to get away, and report the driver to police.
