Defensive driving is defined as being able to operate a motor vehicle with the skills to avoid an accident in a situation where one could possibly occur.

Defensive driving is based on the premise that you, the driver, are actually a very good and safe driver that must be alert and able to react to the dangerous driving that others are engaging in.

Defensive driving utilizes advanced skills and awareness not initially taught to new drivers. The goal of one taking a defensive driving class is to become a proactive driver, in order to avoid dangerous road situations or the poor conduct of other drivers. Specific techniques and basic rules are used to achieve a safer driving experience.

Defensive driving courses are taught across the United States, as well as other countries. Defensive driving schools are sometimes referred to as traffic schools, depending upon the regional area.

In Texas, the term "defensive driving course" is used, while in New York they tend to use the term "traffic school." Anybody can take defensive driving courses to brush up on skills or to qualify for discounts on car insurance premiums.

Most often, individuals are referred to defensive driving courses after being ticketed for a moving violation or having been in an accident. Depending upon the laws of the municipality, the documented completion of a defensive driving course can allow for a dismissal of the ticket.
