Study Notes
Merging and Safe Entry
- Safely merge onto a road by waiting for a sufficient gap in traffic to enter.
Stopping Distance
- Total stopping distance consists of perception distance, reaction distance, and effective braking distance.
Pre-Trip Inspection
- Steering wheel play exceeding 10 degrees (2 inches on a 20-inch wheel) requires immediate attention before driving.
Vehicle Weight and Stopping
- Empty trucks may have longer stopping distances compared to loaded trucks; however, this does not consistently apply to buses.
Driving on Slippery Roads
- When roads are slippery, make turns cautiously to maintain control and avoid skidding.
Accident Scene Care
- A poor rule of thumb during injury care at accident scenes is to keep injured individuals cool, which is not advisable.
Tire Blowouts
- In the event of a tire blowout at 50 mph on a straight highway, refrain from using brakes until the vehicle has decelerated.
Engine Coolant Temperature
- The coolant temperature gauge should gradually rise to normal after starting the engine, indicating proper operation.
Uphill Grade Maneuvering
- When restarting a heavy vehicle on an uphill grade, engage the parking brake until the clutch catches to prevent rolling back.
Speed Management in Slippery Conditions
- Slippery roads increase both stopping distance and difficulty in turning without skidding.
Transporting Hazardous Materials
- Shipping papers for hazardous materials must be stored in the driver's door pouch or in the seat for accessibility.
Using Mirrors While Driving
- Regularly check mirrors to ensure awareness of the vehicle's rear position while making turns.
Lane Positioning in Commercial Vehicles
- Extra caution is necessary for maintaining lane position since commercial vehicles are usually wider than passenger cars.
Ice on Windshield
- Using a brush is typically ineffective for clearing ice from a windshield.
Causes of Vehicle Fires
- Poor ventilation in trailers can lead to fires due to heat accumulation in cargo.
Retarders Function
- Retarders are designed to assist in slowing down vehicles during operation, thereby reducing wear on brakes.
Driving in Hot Weather
- Always check tire mounting and pressure prior to driving in hot weather conditions.
Driving Through Tunnels
- Watch for potential crosswinds when exiting tunnels, which can affect vehicle control.
Work Zones Awareness
- Exercise caution for sharp drop-offs in pavement when navigating through work zones.
Passing Other Road Users
- Assume that vehicles, pedestrians, or cyclists may enter your lane while passing to ensure safe maneuvering.
Hazardous Material Fire Response
- If unsure how to extinguish a hazardous material fire, await professional firefighters to address the situation.
Hydroplaning Response
- On hydroplaning, the first action is to ease off the accelerator to regain control of the vehicle.
Brake Heating Dynamics
- The heavier the vehicle or the faster it travels, the greater the heat absorption required by brakes to stop safely.
Drug Use While Driving
- Prescription medications are permissible as long as they do not impair safe driving abilities.
Gear Selection on Downgrades
- When navigating a long, steep downgrade, utilize a lower gear compared to what would be used for climbing.
Unstable Cargo Awareness
- Be cautious with unstable loads, particularly those involving perishable goods like meat or livestock.
Marking Stopped Vehicles
- If a stopped vehicle is not visible within 500 feet due to hills or curves, reflective triangles need to be adjusted for better visibility.
Rear Wheel Braking Skids
- In vehicles with trailers, be aware that the trailer can cause the towing vehicle to skid sideways during braking.
