Quest Engineering conducts full-scale, at-scene visibility studies and field testing to show sight lines and visibility related to accident parties, eyewitnesses, and security cameras. By reconstructing the precise physical environment of an incident, we provide an objective scientific assessment of human and optical perspective from various vantage points.

​​

Accurate Replication of Operator Perspectives

To preserve and represent the proper perspective, our engineers routinely operate exemplar vehicles and machinery under incident conditions. Our testing experience spans a diverse range of equipment, including:

​

• Commercial & Consumer Fleet: Commercial motor vehicles (CMVs), passenger cars, motorcycles, bicycles, and micromobility scooters.

• Industrial & Maritime Equipment: Heavy construction machinery, material lifts, commercial vessels, and recreational boats.

​​

Advanced Spatial Data & Telemetry Capture

We capture and map dynamic line-of-sight data by deploying specialized technology directly in the field, including:​​

• High-Definition Onboard Cameras: Positioned to capture the proper perspectives.

• Drone Following & Aerial Photogrammetry: Providing bird's-eye spatial context of moving paths and obstruction geometry.

• GPS Equipment & Data Loggers: Synchronizing real-time positioning, speeds, and timing to validate the study’s accuracy against recorded accident data.

​

Resolving Critical Liability Questions

Our visibility and sight-line analyses provide clear, empirically backed answers to pivotal questions:​

• Obstructions: Were there temporary or permanent blind spots, environmental glare, foliage, or structural blockages that impeded a driver's line of sight?

• Conspicuity: Was a pedestrian, hazard, or vehicle prominent enough to be seen in time to perceive and react?

• Witness and Camera Verification: Does the physical evidence agree with eyewitness testimonies and security camera positioning?

Visual Evidence

By transforming abstract spatial questions into clear, definitive visuals, Quest Engineering can educate viewers while reinforcing our comprehensive accident reconstructions, expert reports, and expert testimony​
