Security Driving Is a Statement of Skill, Not a Marketing Term

First and foremost – WHAT IS NOT SECURITY DRIVING – a security driver IS NOT a person who attended an EP Training program and has a driver’s license.  

DRIVING IS A MEASURABLE SKILL
When looking at driving skills, there has been a great deal of research done, money spent, and data collected to better understand how drivers make decisions in emergencies. The end result of all this research is the advancements that have been made in measuring driving skill and, therefore, survivability in an emergency scenario. Simply put, you wouldn’t allow a security professional to carry a gun without first measuring their ability to use it: so why would you let someone drive your principal if you don’t measure their ability to do so?

Defining Security Driving Skill
The automotive engineering community defines driving skills as the driver’s “ability” to use the vehicle’s “capability.” The researchers express driving skill as the percentage of the vehicle’s capability a driver can use before they are no longer controlling the vehicle; loss of control can be defined as; although the driver is holding onto the steering wheel, they along with your principal are a passenger.

 From the Automotive Engineering Research – The Numbers
If a driver can use 40% of the vehicle’s capability, researchers define him/her as a 40% driver; if they can use 60% of the vehicle’s capability, they are a 60% driver. But, here is the bad news, studies have shown that the average driver can use only 40 % to 55 % of the vehicle’s capability. 

After 45 plus years of conducting protective driving programs, I would say that when looking at the “average driver,” the 40 % to 55 % number is accurate and maybe optimistic. If you are responsible for the principal’s safety and security, what is your assurance that the person driving the boss IS NOT an inexperienced or average driver?

The Question – What does the research say is a Good (Security) Driver?

A good driver (Security Driver) can use a minimum of 80% of the vehicle’s emergency maneuvering capability and still maintain vehicle control. The original Scotti School – VDI and ISDA Certification require a Security Driver to use 80% of the vehicle.  

The original Scotti School developed the 80% standard from engineering white papers published by the Society of Automotive Engineers and other testing organizations. Those papers defined average, and what the documents identified as “experienced” skill levels. We (Scotti School) found that neither average nor experienced skill levels were adequate for Security Driving.

 To summarize – As a user of Secure Transportation services, whom do you want driving your principal, if you are paying for a Security Driver, they must be an 80% driver – you do not want an inexperienced (50%) driver or an average (60%) driver transporting your executives.

All the above numbers are easily measured.

A Security Driver’s skill level can easily be measured with an inexpensive onboard computer and an instructor interpreting the data. The device that is commonly used is called a G-Meter. They are used by high-end training programs to measure the vehicle/driver level of performance. These devices range in price from $200 to $1200. But with the advent of the iPhone, iTouch, Blackberry, etc. you can download an application that does the same thing.


This is a snapshot of the ISDA Certified Security Driver standards

Certified Drivers must be measured, via an onboard computer, to use a minimum of 80% of the vehicle’s capability within a specific time-frame. The standards for perception and reaction times are based on studies conducted by Dr. Marc Green.


This post is from the International Security Driver Association

The International Security Driver Association (ISDA) serves the Protective Services community. ISDA’s mission is to support an international forum of protective service providers who share knowledge for the purpose of enhancing the profession.

The most common question we at ISDA get asked is, “Is ISDA for Security Drivers and Secure Transportation Providers only?” The answer is a big NO. ISDA is a valuable resource for all practitioners working in the protection profession. Members of ISDA represent all facets and levels of the protective services profession as an example.

We have been producing informational newsletters for more than 20 years.
