Description
This course will cover the unique characteristics of commercial motor vehicles and the special dynamics at play when one is involved in a crash.
Detailed information of the nomenclature and operation of commercial motor vehicles will provide the student with a level of competence needed to have an adequate understanding of mechanical components, parts and pieces of the commercial motor vehicle and how they may factor into the investigation. To reinforce the concepts presented, the student will conduct “hands-on” exercises and vehicle testing during the course.
Topics will include:
- Tractor-trailer nomenclature
- Brake systems: configuration and operation
- Wheels, rims and tires
- Steering suspensions and frames
- Trailer coupling devices - fifth wheels
- Driver concerns - log books
- Vehicle components
- Center of mass determinations
- Skid mark measurements and speed analysis
- Jackknifing
- Rollover
- Vehicle dynamics in braking
- Weight shifting
Target Audience
The course enrollment is intended primarily for Virginia law enforcement personnel. On rare occasions, non-law enforcement personnel will be allowed to take the course on a case-by-case basis.
