Study Notes
Counter Steering
- Counter steering involves turning the wheel in the opposite direction after an initial steer to avoid an obstacle.
- Essential in emergency situations to regain control of the vehicle.
Responding to a Tire Blowout
- Do not brake immediately if a tire blows out; allow the vehicle to slow naturally.
- After deceleration, brake gently and steer off the road to stop safely.
I.P.D.E. Method of Driving
- The I.P.D.E. method stands for Identify, Predict, Decide, Execute.
- Serves as a systematic approach for defensive driving and enhancing visual perception in traffic.
Mirror Usage
- Mirrors have blind spots that they cannot cover; maintaining awareness of these is crucial.
- Convex mirrors distort size and distance of objects, necessitating careful checks.
Cargo Securement
- All cargo, regardless of size, requires a minimum of two tie downs for safety.
Returning to the Road from an Emergency Stop
- If unable to stop before returning to the road, reduce speed to 20 mph or less before merging back.
- Avoid abrupt braking; gradually lower speed to ensure control.
Tie Down Regulations
- Cargo tie downs must collectively be able to lift one and a half times the weight of the cargo secured.
- Compliance ensures safety and adheres to federal regulations for cargo securement.
Effects of Wet Brakes
- Wet brakes can lead to decreased braking power, wheel lock-ups, and potential trailer jackknife situations.
- Being aware of these effects is vital when driving in heavy rain.
Distance to Look Ahead
- Good drivers should look 12-15 seconds ahead, equivalent to traveling that distance at current speed.
- This anticipation helps in making informed driving decisions.
Speed Management on Slippery Roads
- On wet surfaces, reduce speed by one-third; on packed snow, reduce speed by half.
- Slippery conditions extend stopping distances and make turning difficult, necessitating slower speeds for safety.
Gear Selection on Downhill Grades
- When driving downhill, select a lower gear than what was used when climbing the hill.
- This helps maintain control and prevent excessive acceleration.
Correcting a Rear Wheel Acceleration Skid
- To correct a rear wheel skid caused by acceleration, stop accelerating.
- If driving on very slippery surfaces, disengage the clutch for better traction recovery.
Fire Extinguisher Use
- When using a fire extinguisher, aim at the base of the fire for effective suppression.
- Positioning is critical to maximizing the effectiveness of the extinguisher.
