Efficacy Studies

STUDIES VERIFY THE EFFECTIVENESS OF NTSI’S INSTRUCTION

Independent research shows that NTSI’s programs are effectively reducing traffic violations and collisions. Rather than a program that only emphasizes law and knowledge, we attribute our success to Choice Theory, a scientifically-based instructional strategy that emphasizes personal responsibility. However, our course content goes a step further, utilizing the the Values + Attitudes = Behavior™ methodology developed by our founder and owner Jeffrey M. Chase, PhD.

Do you hear excuses like these?

“I speed because my route is too long!”

“I didn’t see the light change because I needed to call the office.”

“I drink during lunch because it helps in my sales efforts.”

If these excuses sound all too familiar, consider a program consistently proven to:

  • Lower the accident rate by 21%
  • Lower the rate of traffic violations by 63%
  • Deliver levels of participant satisfaction that exceed 96%

Over the years, NTSI’s defensive driving programs have been the subject of analysis. Summarized here are the findings of three well-reasoned studies from independent researchers.

NTSI Point Insurance Reduction Program

Study 1: New York State Department of Motor Vehicles

Researchers report that NTSI’s New York Defensive Driving Classroom and Online program:

  • Reduces accident rates (21%)
  • Reduces violations (64.5%)
  • Reduces accident rates of males over 50
  • Reduces accident rates of males under 30

Data for the study is supplied by New York’s Division of Research and Evaluation. In addition to NTSI, programs evaluated include National Safety Council (NSC), AARP, Driver Training Associates, National Traffic Safety, Safety Training, New York State, New York Telephone, and Police Emergency Vehicle Operations.

NTSI significantly reduces collisions

Study 2: State of Florida Legislature

The Florida State Legislature commissions studies to assess the effectiveness of driver improvement programs in reducing crashes and violation recidivism. Through a statistical analysis, Florida’s Department of Motor Vehicles found that NTSI’s program:

  • Significantly reduces violations
  • Significantly reduces collisions

Data supplied by Florida’s Information Systems Administration (ISA). NTSI program and the programs of six others were included in the study. Studies conducted using both a control and treatment group.

Court validates program efficacy

Study 3: Arizona Supreme Court

The Arizona Supreme Court conducted a study to assess the effectiveness of defensive driving programs in reducing traffic offense recidivism. It is estimated that 29,000 civil traffic moving offenses are avoided each year as a result of class attendance. The study found:

  • Participants had a recidivism rate of 14.2% lower than those who did not
  • 16-19 year olds were 24% less likely to receive a second violation
  • Non-participants were 30% more likely to be cited for one of the more serious driving offenses

Data from January to November of 1999 was used for the study.

94% plan to improve driving safety

The Administrative Office of the Court, State of Arizona, surveyed 5,000 participants in NTSI’s defensive driving class. The participants said that they:

  • Rate the program “excellent” or “good” (96%)
  • Learned something new about safety (96%)
  • Would recommend the program to others (95%)
  • Plan to improve their driving safety (94%)

Data from January and November of 1999 was used for the study and compiled by the Tucson City Court.
