What type of damage is often observed in high-speed collisions?

In high-speed collisions, inertia damage is a significant type of damage that occurs. This form of damage results from the laws of physics, particularly Newton's first law, which states that an object in motion will continue to move in that direction unless acted upon by an external force. In a high-speed scenario, when a vehicle suddenly stops due to impact, the contents within the vehicle, including passengers and certain parts of the vehicle itself, continue to move forward at the previous speed until they collide with another object (like a seatbelt, airbag, dash, or windshield). This results in injuries to occupants and also contributes to additional structural damage to the vehicle that may not be immediately visible.

Inertia damage is particularly relevant as it can exacerbate the effects of direct impact damage, often leading to more serious consequences in terms of injury and structural damage as compared to slower collisions. Understanding inertia damage is essential for appraisers, as it provides insights into the full extent of the damage and the potential implications for vehicle safety and occupant protection.
