Heavy Truck & Bus

Robson Forensic employs truck and bus experts with decades of industry experience. These experts understand the handling dynamics of heavy vehicles and the physics required to accurately and dependably reconstruct collisions involving these massive vehicles. Our heavy vehicle experts bring decades of experience designing, testing, and building tractor trailer combinations, passenger buses, and motor homes.


Our heavy truck and bus experts are degreed engineers who worked for heavy vehicle or heavy vehicle parts manufacturers. Our experts understand how these vehicles are built, how they handle, and how they behave before, during, and after a crash.

Reconstructing a crash involving heavy trucks or buses can be considerably more complicated than conventional vehicle crashes and may require consideration for several factors not relevant in automobile to automobile crashes.

  • Size: Trucks are bigger and heavier than automobiles, up to 40 tons, compared to 1-2 tons. As the difference in mass between colliding vehicles increases, normal calculation models used in crash reconstruction become less reliable.
  • Configuration: There are many different configurations of heavy trucks, from a single unit straight truck to 3 trailer triples. Truck configurations effect vehicle maneuvering and stopping characteristics.
  • Damage: Damage to the truck in a truck-automobile crash is usually minimal compared to the auto. This may require more sophisticated approaches to calculating crash forces.
