The standard Safe Practices for Motor Vehicle Operations, ANSI/ASSE Z15.1, defines defensive driving skills as "driving to save lives, time, and money, in spite of the conditions around you and the actions of others." This definition is taken from the National Safety Council's Defensive Driving Course. It is a form of training for motor vehicle drivers that goes beyond mastery of the rules of the road and the basic mechanics of driving. Its aim is to reduce the risk of collision by anticipating dangerous situations, despite adverse conditions or the mistakes of others. This can be achieved through adherence to a variety of general guidelines, such as following the assured clear distance ahead and two second rules, as well as the practice of specific driving techniques. Some motorists describe defensive driving as "driving as if everyone else on the road were drunk."
History
A driver safety program called the Driver Example Program was developed in 1964 by Chris Imhoff of the National Safety Council. The program instituted a Defensive Driving Course . Defensive Driving Courses, along with Instructor Development Courses were offered beginning 1964 and 1965, typically through corporate sponsorships.
General principles
Driving defensively includes:
General principles:
* Controlling your speed.
* Looking ahead and expecting the unexpected.
* Being alert and distraction free.
Regarding other participants in traffic:
* Preparedness for all sorts of actions and reactions of other drivers and pedestrians.
* Not expecting the other drivers to do what you would ordinarily do.
* Adjusting your speed before entering a bend, in order to avoid applying the brakes in the middle of a bend.
Training and courses
Several US government agencies, non profit organizations, and private schools have launched specialty courses that improve the public's driving skills. In the United States a few of the familiar courses in defensive driving include Alive at 25, DDC or Defensive Driving Course, Coaching the Mature Driver, Attitudinal Dynamics of Driving, Professional Truck Driving, and DDC for Instructors. In relation to this, the government has launched active air bag and seat belt safety campaigns that encourage high visibility enforcement. In addition to improving one's own driving skills, many US states provide an incentive to complete an approved defensive driving course by offering mandated insurance discounts or a way to mask a traffic ticket from one's driving record. In some instances, these courses are referred to as traffic school or a defensive driving school. States with the biggest incentives include Arizona, California, Florida, Nevada, New Jersey, New York, and Texas. A number of private providers offer a variety of courses. The methods and styles of the courses vary; but they are typically less comprehensive than training to pass an advanced driving test through the Institute of Advanced Motorists, Royal Society for the Prevention of Accidents Advanced Drivers and Riders, or British Motorcyclists Federation Blue Riband. While US training has typically focused on handling skills – such as the Bondurant school of high-performance driving – British training has emphasised roadcraft. Defensive and advanced driving and motorcycling are commonly recognized in the UK, championed by charities such as the Institute of Advanced Motorists and the Royal Society for the Prevention of Accidents' Advanced Drivers and Riders.
Benefits of roadcraft
British research has shown advanced drivers who use the roadcraft system of car control are safer and have better fuel efficiency too. The roadcraft system was devised in 1937 by racing driver Mark Everard Pepys, 6th Earl of Cottenham, to reduce accidents in police pursuits. A study by Brunel University found advanced drivers who had successfully completed the Institute of Advanced Motorists training were nearly 70% better in all aspects of their driving – from steering to judging distances and speed. Earlier research by Britain's Transport Research Laboratory that concluded drivers are less likely to crash if they have reached a measurable higher driving standard. Unpublished research by IAM Surety showed that insurance claims by members of the Institute of Advanced Motorists were far cheaper than comparable non-members. Additionally – according to the Association of Motor Insurers – there is a reduction in claims for the first four years after passing the Institute of Advanced Motorists test.
