Every Collision Tells A Story—We Help You Understand It.
The engineers at DJS Associates, Inc. apply engineering principles and state-of-the-art technologies to analyze physical evidence, determine contributing factors, and reconstruct the sequence of events leading up to, during, and following a vehicular impact.
Complex collisions are rarely limited to passenger vehicles. Our collision reconstruction experts are experienced in analyzing crashes that involve:
- All-Terrain Vehicles (ATVs), Golf Carts, and other Recreational Vehicles.
- Bicycles, Pedestrians, or Motorcycles.
- Buses, Construction Equipment, Tractor-Trailers, and other Heavy-Duty Vehicles.
A detailed reconstruction that follows proper scientific methodology is often necessary to address specific issues, such as:
- Ability to Avoid
- Chain Reaction Collisions
- Distracted Driving
- Low-Speed Impacts
- Perception-Reaction Time
- Phantom Vehicles
- Right-of-Way
- Roadway Design
- Vehicle Rollover Events
- Visibility
