The aspect of defensive driving is one of the best strategies of road safety because it is built on the anticipation of danger before it becomes an emergency and not on response only after the problem is manifested. Defensive drivers do not believe that other drivers will be law-abiding at all times, unlike the assumption that some mistakes may occur. Such an attitude causes vigilance, consciousness and readiness. The drivers are naturally more alert, more tolerant and less violent when they anticipate the unexpected. Defensive driving makes driving a conscious responsibility instead of a routine activity that is meant to help in saving lives.

One of the key rules of defensive driving is to drive with the appropriate following distance. Much of the accidents occur since the drivers, in their attempts to follow closely, lack enough time to respond when a traffic jam suddenly halts or decelerates. Tailgating lowers the reaction time and increases a collision impact. Space between vehicles should be left to provide a safety margin. This cushion helps the drivers to make a slow brake, steer off in case of necessity, and prevent panic. At higher speeds with increased stopping distances, following distance is even more essential when it is raining, foggy, in heavy traffic, etc.

Defensive driving involves constant scanning of the road which is also a fundamental aspect of the defensive driving. Early notification will allow the drivers enough time to moderate speed or position.

The issue of speed management is crucial in the prevention of accidents. Over speeding beyond the standards of the conditions decreases control and rise in the distance to stop. It might be unsafe to drive even at the speed limit during bad weather or during rush hour. Reduced speeds have a higher reaction time and control of the vehicle. Prudent speed decisions lower the chances of accidents as well as their impact.

The best thing about defensive driving is avoiding distractions. Cellular phones, eating, controlling, and over-talking all inhibit the focus on the road. A small distraction can cause one to miss vital information even in a couple of seconds. Offensive drivers have their eyes on the road, hands on the wheel and mind on driving. 

The driving behavior is highly affected by emotional control. Frustration, anger and impatience enhance risky behaviors like driving faster, tail-ganging and aggressive overtaking. The defensive drivers are aware of emotional provocations and decide to keep calm. Being calm enables one to think better and make judgments. Rational motorists react as opposed to responded.

Defensive driving makes the driver more confident, as they are ready to act responsibly.Not only the driver but also the passengers and pedestrians, as well as other drivers, are more likely not to be involved in accidents and become safer on the road. Any safe choice will have a beneficial effect on safer road.
