Executive Protection and Secure Transportation Podcast

Last year ISDA conducted an Executive Protection Security Driver Training Survey. The 2020 ISDA Training Survey Results Our goals were to determine the dollar value of the Executive Protection and Security Driving training market. To acquire metrics concerning what motivates potential students to attend one program over another- such as - How did they fund their training? - How many training programs have they attended during their career? - What was their motivation to participate in the training programs? We also wanted to determine what training subjects were covered and the average length...

Episode 168 - The Science of Backing Up show art Episode 168 - The Science of Backing Up

Executive Protection and Secure Transportation Podcast

Driving in reverse is a valuable driving skill to have.   Backing up slowly can be a problem but backing up fast is hard and dangerous if not done correctly. With that said, it is by far one of the most valuable driving skills to have, and a Security Driver can acquire. Along with being hard to do, it is hard to teach and, if not taught correctly – dangerous. What makes it hard and hazardous is the definition of fast. How fast you can drive in reverse is limited to the vehicle's gearing; in most vehicles, you can drive as fast in reverse, or a little quicker, as you can in 1st gear....

Episode 167 - The Security Drivers Triangle show art Episode 167 - The Security Drivers Triangle

Executive Protection and Secure Transportation Podcast

The Essence of Security Driving is Found in the Security Drivers 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 a triangle's failure causes an accident or a successful ambush, the driver, the...

Executive Protection and Secure Transportation Podcast

There are two words that are often used in the automotive industry and protective driver training vernacular the words are handling and cornering. To get a better understanding of how the driver interacts with the vehicle requires understanding the difference between Handling and Cornering. While conducting a driver training program understanding this interaction is a must – when running a secure transportation operation, knowledge of this interaction adds to the principal’s safety and security.

Executive Protection and Secure Transportation Podcast

Ensuring the passengers’ safety and security requires the driver to have the knowledge, skill, and experience to control the vehicle when confronted with an emergency. The emergency does not necessarily need to be a security scenario; it can often be an accident-producing situation.  As we have mentioned many times in the past, research and science define driving skill as the driver’s “ability” to use the vehicle’s “capability.” Former  or Scotti School students know that we were and are anal about training our students to maximize the vehicle’s capability.

Episode 164 - Vehicle Dynamics and Passing show art Episode 164 - Vehicle Dynamics and Passing

Executive Protection and Secure Transportation Podcast

The topic for this week’s episode is Vehicle Dynamics and Passing. Passing the vehicle in front of you is one driving skill we often do but don’t give it much thought. Once you decide to pass a vehicle in an urban environment, realize, and remember that you and your car will be spending a good deal of time in the wrong lane. To give you an idea of how much time and distance, consider this scenario. If you are traveling at 50 mph or 80KPH and passing the average sedan or SUV going 40 mph or 64 KPH, you will need about 10 seconds and 736 feet or 225 Meters to complete the pass...

Executive Protection and Secure Transportation Podcast

Hello, and welcome to episode 163 of the EPST podcast. I'm your host, Larry Snow. The topic for this week’s episode is the huge increase in carjackings. Statistically, driving the principal from point A to point B has been the highest risk the principal faces during their daily routine. A not so new risk needs to be added to that trip, and that is the dramatic increase, in fact, a staggering increase in carjackings in parts of the United States during the pandemic. If you are not familiar with the term, a carjacking is a violent, potentially fatal version of auto theft. Do a Google search...

Executive Protection and Secure Transportation Podcast

Understeer and Oversteer are terms used to explain vehicle characteristics, and they are important signals transmitted to you by the vehicle, it is how the vehicle communicates to you. It is the vehicle’s way of telling you what you should do next. In a nutshell, understeer and oversteer are the interrelationships of the front and rear ends of the car. If you drove around a corner or made an emergency maneuver that created 3200 lbs pushing on the CG of your vehicle – in the perfect world your tires would be pushing back 1600 lbs. front and rear. This would be called neutral steering, and...

All vehicles have inherent characteristics that, if not understood and monitored, can decrease a vehicle’s performance and create a dangerous scenario for the principal. There are numbers that represent these vehicle characteristics; most can be found in the owner’s manual.

The Security Driver does not need to understand the science behind these numbers, but they need to know how these numbers and changes in these numbers affect the principal and passengers’ safety and security.

The top five vehicle characteristics are:

  • The vehicles maximum payload capacity
  • The tires load rating.
  • Tire pressure
  • The vehicles Statics Stability Factor – SSF (difficult to find)
  • Center of Gravity (difficult to find)

The wrong combination of these five vehicle characteristics can and has proven to be a problem.

The wrong combination is defined as:

  • The vehicle’s payload at maximum or exceeded
  • Low Tires Pressures
  • Tire Load Rating has been exceeded
  • High Vehicle Center of Gravity
  • A Low Vehicle Static Stability Factor (SSF) 

Definitions 

Payload 

The payload is defined as the combined, maximum allowable weight of cargo, occupants, and optional equipment that the vehicle is designed to carry. The payload is an indication of how many passengers and cargo the vehicle can accept. That number is set by the vehicle manufacturer and is vital to passengers’ safety and security.

You can also use Google to find the payload of your vehicle; as an example, if you want to find the payload of a Suburban, you would type in “Payload for Suburban,” This is an example of what you would get.

Suburban Payload

Somewhere on the vehicle, there is a sticker that will supply the payload numbers; this is an example. 

Payload Vehicle Sticker

Or you can find the numbers in the vehicle’s manual.

Improperly loaded vehicles or those that exceed the weight rating will have a dramatic effect on performance. Steering, maneuverability, braking, and acceleration are all affected. Most important, stopping distances are dramatically impacted. 

The Tires Load Index and Load Carry Capacity

The load index explicitly indicates how much weight a tire can carry. To find your tire’s carrying capacity, look for the load index number on its sidewall.

The load index number indicates a tire’s carrying capacity when inflated to its maximum load sustaining pressure. It corresponds to another number in an index, which tells you how many pounds of weight the tire can carry.

how much weight can your tires carry

Static Stability Factor and Center of Gravity – SSF, and CG 

Another characteristic that can decrease vehicle performance and safety is the vehicle’s static stability factor (SSF). This is especially true in SUVs. Click here for more information.

Tire Pressure Basics

Maintaining correct tire pressure helps optimize tire performance and fuel economy. Correct tire inflation pressure allows drivers to experience tire comfort, durability, and performance designed to match the needs of their vehicles. Proper tire inflation pressure also stabilizes the tire’s structure, blending the tire’s responsiveness, traction, and handling.

Tire Pressure Monitoring System

Almost everyone has seen the tire pressure monitoring system (TPMS) warning light appear on the dashboard. It warns you that at least one or more tires are significantly under-inflated, possibly creating unsafe driving conditions. There are pressure-sensing transmitters mounted inside each tire and sent to a central computer (ECU), which display the tire pressure readings on the dashboard. The problem is that the warning light on the instrument panel does not come on until there is a 25-percent drop in tire pressure. By the time the warning light displays, you and the passengers are in a very unsafe vehicle.
