Study Notes
Vehicle Inspection and Safety
- Conduct inspections for safety of yourself and others on the road.
- During trips, check instruments, air pressure, temperature gauges, mirrors, tires, cargo, and lights.
Steering and Suspension Systems
- Key steering components include tie rod, steering column, gear box, reservoir, steering knuckle, draglink, and spindle.
- Common suspension defects: cracked spring hangers, broken leaves, leaking shock absorbers, and faulty air suspension.
Emergency Equipment Requirements
- Must carry fire extinguishers, spare electrical fuses, and warning devices for parked vehicles.
Tire Regulations
- Minimum tread depth: 4/32 inch for front tires, 2/32 inch for other tires.
Pre-trip Inspection Checks
- Inspect front axle, steering system, windshield, wipers and blades, lights, and reflectors.
Wheel Bearing Maintenance
- Check wheel bearing seals for rips, tears, cracks, and leaks.
Emergency Supplies
- Carry three red reflective triangles for roadside emergencies.
Brake System Testing
- Test hydraulic brakes for leaks by checking pads, shoes, hoses, and reservoir for brake fluid.
Safe Inspection Practices
- Keep the starter key in your pocket during inspection to prevent vehicle rolling.
Driving Techniques
- Back towards the driver’s side for better visibility.
- On hills, use the parking brake or accelerate to avoid rolling back.
Importance of Helpers
- Use a helper when backing up to supplement vision and provide direction.
- Agree on clear hand signals; the most important is a signal to stop.
Downshifting and Speed Management
- Downshift when going into a curve or downgrade.
- Automatic transmissions should also downshift in similar conditions.
Shifting and Distance Awareness
- Shift based on engine and road speed; look 12 to 15 seconds ahead for hazards.
Watch for Traffic Changes
- Monitor traffic and changing road conditions.
- Utilize mirrors for expanded visibility around the vehicle.
Communication in Driving
- Communicate intentions to promote safety for yourself and others.
Reflector Placement
- When stopped on a divided highway, place reflectors at 10, 100, and 200 feet towards approaching traffic.
Stopping Distance Components
- Total stopping distance is the sum of perception, reaction, and braking distances.
Speed and Stopping Distance Relation
- Stopping distance increases by four times if speed doubles.
Truck Braking Capability
- Empty trucks do not have better braking capabilities; this statement is false.
Hydroplaning and Black Ice
- Hydroplaning occurs when tires lose traction over water.
- Black ice is a thin layer of ice that allows visibility of the road underneath.
Following Distance Calculations
- Measure following distance by timing seconds between passing a marker and the vehicle ahead.
- For a 30-foot vehicle at 55 mph, maintain a 4-second following distance.
Maintaining Safe Following Distance
- Increase following distance if another vehicle is tailgating; do not decrease it.
Turning Awareness
- Swinging wide to the left before a right turn can lead to other drivers trying to pass on the right.
