Study Notes
Counter-Steering
- Counter-steering involves turning the steering wheel back in the opposite direction to avoid a traffic emergency.
Look Ahead Distance
- Drivers should look ahead approximately 1/4 mile while driving at highway speeds.
Retarders Function
- Retarders assist in slowing down the vehicle and minimizing brake wear.
Signaling During Turns
- Continuous signaling is necessary while turning to keep both hands available for safe steering.
Exhaust System Risks
- A broken exhaust system can allow toxic fumes to enter the vehicle's cab or sleeper berth, creating a safety hazard.
Pre-trip Inspection Standards
- Steering wheel play should not exceed 10 degrees (2 inches on a 20-inch wheel) for safe operation.
Double-Clutching and Shifting
- The tachometer can indicate the appropriate time to shift gears during double-clutching.
CDL Medical Certification
- CDL medical certificates must be renewed every two years.
Gear for Downhill Grades
- A lower gear is recommended for descending long, steep hills compared to the gear used for ascent.
Starting from a Stop
- If the drive wheels start to spin when applying power, release the accelerator immediately.
Speed Increase on Downgrades
- A vehicle's speed naturally increases on downhill slopes due to gravitational force.
Stab Braking Technique
- Stab braking involves engaging the brakes fully and then releasing them after the wheels lock.
Written Vehicle Inspection Report
- A written vehicle inspection report must be signed if the previous driver noted defects.
Placards Placement
- Placards must be displayed on all four sides of a transport vehicle.
Consequences for DUI
- A first offense of driving a commercial vehicle under the influence results in a minimum one-year CDL suspension.
Pre-trip Inspection Exclusions
- Valve clearance is not included in the engine compartment pre-trip inspection.
Handling Water Hazards
- To maintain braking effectiveness when driving through water, gently apply the brakes while traversing the area.
Railroad Grade Crossing
- Stopping at railroad grade crossings is mandatory if the cargo requires it under regulations.
Making Wide Turns
- To effectively turn from a two-lane street with a long vehicle, begin the turn halfway through the intersection.
Containerization Loads
- Containerization refers to loads typically transported partially by rail or ship.
Controlled Braking
- Controlled braking maintains a straight trajectory while slowing down the vehicle.
Turning from Wide Vehicles
- When turning left onto another street, initiate the turn halfway through the intersection to accommodate wider turns.
Coolant Temperature Gauge
- After starting the vehicle, the coolant temperature gauge should gradually rise to indicate normal operation.
Cargo and Stability
- Unstable cargo types, such as livestock or hanging meat, require cautious driving through curves.
Vehicle Overhead Clearance
- The height of a vehicle can change based on cargo weight, impacting overhead clearance.
Accident Scene Care
- A poor practice at an accident scene is to keep injured persons cool.
Tire Care in Hot Weather
- It’s crucial to check tire mounting and air pressure before driving, particularly in hot weather.
Assumptions When Passing
- Always presume that pedestrians, vehicles, or cyclists may encroach into your lane while passing.
Blood Alcohol Concentration Factors
- To accurately gauge blood alcohol concentration, one must know the individual’s weight.
Emergency Road Departure
- In a traffic emergency requiring you to leave the road, refrain from braking until necessary.
