Security Driver Triangle

The driver’s ability to avoid vehicle violence does not depend solely on their ability to control the vehicle. A driver is at the mercy of the environment, and of the vehicle, they are driving.

Driving, any form of driving, is a balance, and that balance is called the “driving system.” The driving system is made up of three components: THE DRIVER, THE MACHINE, and THE ENVIRONMENT. In our world, it is called the Security Drivers Triangle. If there is an accident or a successful ambush it is caused by a failure of the triangle, the driver, the vehicle, or the environment failed.

The Driver
Most accidents or ambushes are caused by driver error. In the nonsecurity world, the proof lies in the numbers. Some 89 percent of all vehicular accidents are caused by driver error. The driver is responsible for the successful implementation of the DRIVER/MACHINE relationship. The driver has to know and understand the capabilities of the vehicle driver combination. The driver’s capability to maneuver out of an emergency is a measurable skill. A skill level is a number that indicates how much of the vehicle capability the driver can use. The simple fact is the higher the number, the better the chances of survival. Given a vehicle, and an environment they must drive through, a security driver has to know what they are capable of and better yet what they are not capable of.

The Machine
Most passenger vehicles are good handling vehicles. But there are scenarios where the vehicles handling capabilities are lowered due to an increase in the vehicles security posture (armored vehicles). However, no matter how well or poorly a vehicle handles, it is only a machine, and like all machines, has its limitations, some vehicles higher than others. The vehicle, like the driver, has a measurable capability, which translates to a number, the higher the vehicles number the greater the chances of survival.

Driver/Machine
You cannot separate the driver from the vehicle. A good security driver understands vehicle dynamics and works to anticipate changes in the vehicle behavior and is ready to maximize the capability of the vehicle. A bad driver just reacts to whatever happens.

The Environment
Driving in the nonsecurity world the environment is the weather – traffic – road design. If the road surface has been modified by nature, then the driver and machine portion of the driving system must cope with these changes.

In the security world, the environment includes the security conditions the driver has to maneuver through. The driver/vehicle combination can have high survival numbers, but in a high-risk environment they are at the mercy of the security environment – as much as possible try to control the environment, but there are times especially in a high-risk environment where that is not an easy task.
