| Term | Definition according to Complete Handbook of Security Driving | Related concepts |
|---|---|---|
| Vehicle Dynamics | The study of how vehicles move, respond, brake, steer, accelerate, and transfer weight under driver input and environmental conditions. | ABS, ESC, Understeer, Oversteer, Weight Transfer, Braking Distance, Armored Vehicle, Electric Vehicle |
| Tire Grip | Tire grip is the frictional force between the tires and the road that allows the vehicle to accelerate, brake, steer, and remain stable during movement. | Contact Patch, Weight Transfer, Braking Distance, Aquaplaning, Vehicle Dynamics, Weather |
| Braking Distance | The distance a vehicle travels from the moment braking begins until it comes to a complete stop. | Defensive Driving, ABS, Tire Grip, Weight Transfer, Armored Vehicles, Driver Performance |
| Aquaplaning | Aquaplaning, also known as hydroplaning, occurs when a layer of water forms between the tires and road surface, causing a sudden loss of traction and reducing the driver's ability to steer, brake, or accelerate effectively. | Tire Grip, Contact Patch, Weather, Braking Distance, Route Planning, Vehicle Dynamics |
| Driver High Eye | Driver high eye refers to the elevated visual perspective available to drivers of SUVs and similar vehicles, allowing earlier observation over traffic, route changes, potential blockages, and environmental anomalies. | SUVs in Executive Protection, Situational Awareness, Motorcade Operations, Center of Gravity, Braking Distance, Vehicle Dynamics |
