Crash Investigations Class 315 Practice Test

Post-crash inspections focus on uncovering how the vehicle behaved and whether any systems failed or were compromised during the crash. Investigators look at mechanical function and integrity—steering, braking, suspension, drivetrain, and tires—to see if a defect could have contributed to the incident. They also assess load conditions, such as weight distribution and whether any cargo or structural damage affected performance. Checking occupant safety equipment—airbags, seat belts, pretensioners—and whether they deployed or were ready to deploy helps determine if safety systems functioned as intended. This information is key to understanding what happened and how to prevent similar crashes in the future.

Other options don’t fit because fuel efficiency, vehicle color, or the owner’s driving history do not reveal the vehicle’s mechanical state or safety-system status at the time of the crash.
