Course Description
This course familiarizes students with truck instruments and controls and performing basic maneuvers required to drive safely in a controlled environment and on the driving range. Each student must complete 12 hours behind the wheel instructional time in range operations, including operating a tractor trailer through clearance maneuvers, backing, turning, parallel parking, and coupling/uncoupling.
Course Outcomes
Introduce Vehicle Instruments and Controls
Order Description
1 Identify and state the function of engine controls
2 Identify and state the function of controls related to vehicle movement
