Study Notes

Vehicle Inspection and Safety

  • Vehicle inspection is primarily for ensuring safety.
  • During a trip, check instruments, gauges, mirrors, tires, cargo, lights, and more.

Steering and Suspension Systems

  • Key steering components include: steering wheel, tie rod, hydraulic fluid reservoir, gear box, and power steering cylinder.
  • Suspension defects can involve: broken spring hangers, damaged air suspension, and leaking shock absorbers.

Emergency Equipment and Tire Requirements

  • Essential emergency equipment includes: fire extinguisher, three reflective triangles, and spare fuses.
  • Minimum tread depth is 4/32 inch for front tires and 2/32 inch for rear tires.

Pre-Trip and Backing Procedures

  • Walk-around inspection checks: front axle, steering system, windshield, lights, and wipers.
  • Check wheel bearing seals for leaks.
  • For safety, keep starter key in your pocket during pre-trip inspection.

Backing Techniques

  • Back toward the driver’s side for improved visibility.
  • Engage the clutch partially to prevent rolling back on a hill; use the parking brake as needed.
  • Use a helper when backing due to blind spots.

Shifting and Braking

  • Most crucial hand signal to agree on with a helper is "stop."
  • Downshift before descending hills or entering curves; for automatic vehicles, downshift when going downhill.
  • Shift timing is determined by engine RPMs or road speed.

Safe Driving Practices

  • Look ahead 12 to 15 seconds for potential hazards.
  • Key observations include vehicles emerging into your lane or brake lights from slowing vehicles.
  • Use mirrors as the primary way to monitor sides and rear of the vehicle.

Communication and Reflector Placement

  • Communicating in driving means signaling intentions to other drivers.
  • When stopped on a divided highway, position reflectors at 10 feet, 100 feet, and 200 feet from your vehicle towards oncoming traffic.

Stopping Distance and Driving Conditions

  • Total stopping distance consists of perception, reaction, and braking distances.
  • Doubling your speed increases stopping distance by four times.
  • Empty trucks do not have better braking capabilities.
  • Hydroplaning occurs when tires lose contact with the road surface, leading to a lack of traction.
  • Black ice is a thin, invisible layer of ice that reflects the underlying road surface.

Following Distance

  • To gauge following distance, count seconds from when the vehicle ahead passes a landmark until you reach it.
  • Recommended following distance for a 30-foot vehicle at 55 mph is four seconds.
  • Do not reduce following distance if tailgated; maintain it for safety.
  • Swinging wide left before a right turn can create passing risks on the right side.
