32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Repeat-back confirmation

The receiver restates an instruction in their own words so the sender can confirm it was understood correctly before the work begins.

SBI feedback

A feedback structure that names the Situation, the Behavior observed, and the Impact of that behavior, then agrees on one specific corrective action.

Toolbox talk

A short pre-shift team briefing covering the tasks, hazards and their controls, required PPE, individual assignments, and an invitation for questions.

Five Ws and one H

A handover and reporting checklist covering what happened, who was involved, when, where, why it happened, and how it was handled.

Five Whys

A root-cause technique that repeatedly asks why a problem occurred until the answer points to a process failure that can be corrected permanently.

Pareto analysis

Ranking problems by frequency or cost to show that roughly 80 percent of effects come from about 20 percent of causes, so effort goes there first.

Payload calculation

Payload equals the permitted gross vehicle weight minus the vehicle's tare or curb weight, and must also stay within the lowest axle and tyre rating.

PDCA cycle

Plan the change using data, Do a controlled trial, Check the measured result against the target, and Act by standardising the fix or repeating the cycle.

RA 4136

The Philippine Land Transportation and Traffic Code, which sets the basic rules on speed, overtaking, right of way, signals, and duties after a crash.

Overtaking rule

Pass on the left after signalling and confirming the lane is clear; a right-side pass is permitted only when the vehicle ahead is turning left.

Flashing yellow signal

A traffic light display meaning proceed only with caution, giving way to vehicles and pedestrians already lawfully inside the intersection.

Right of way, uncontrolled intersection

Where no signs or signals control the junction, yield to traffic already inside it and to the vehicle approaching from your right.

Air brake leak test

With full pressure and the engine off, leakage must not exceed 3 psi per minute with brakes released or 4 psi per minute with brakes applied.

Tug test

After coupling, pull gently forward with the trailer brakes locked; if the tractor moves without resistance the fifth wheel jaws are not locked.

Low air pressure warning

A buzzer and lamp must activate before system pressure falls below 60 psi, warning the driver before the spring brakes apply automatically.

Steering free play check

With the wheels straight ahead, the steering rim should move no more than about 10 degrees, roughly 2 inches on a 20-inch wheel, before the road wheels respond.

Off-tracking

The tendency of a trailer's rear wheels to follow a path inside the tractor's front wheels; it increases with wheelbase and with the sharpness of the turn.

Trailer sway recovery

Ease off the accelerator smoothly, hold the steering straight, and if fitted apply only the trailer brakes; never brake hard or steer against the sway.

Controlled braking

Applying the brakes firmly enough to slow the vehicle without locking the wheels, releasing as the wheels begin to lock, and repeating as needed.

Hydroplaning speed

The approximate speed in miles per hour at which tyres begin to ride on water is nine times the square root of the tyre pressure in psi.

Slack adjuster

The linkage that converts brake chamber pushrod travel into rotation of the brake camshaft; excessive pushrod stroke means the brakes are out of adjustment.

Battery state of charge

A resting reading near 12.6 volts indicates a fully charged battery, while about 12.4 volts indicates roughly half charge and needs investigation.

Fifth wheel lubrication

Greasing the fifth wheel plate and kingpin at scheduled intervals reduces steering effort, noise, and wear on the coupling components.

Working load limit

The maximum load a chain, strap, binder, or fitting is rated to carry; the marked figure must never be exceeded when securing cargo.

Aggregate WLL rule

The combined working load limits of all tiedowns used should be at least half the weight of the cargo being secured.

Bill of lading

The transport document listing the goods, quantity, consignor and consignee; it is checked against the load before departure and signed on delivery.

PASS extinguisher method

Pull the pin, Aim at the base of the flame, Squeeze the handle, and Sweep from side to side until the fire is extinguished.

Brake failure response

Pump the pedal, downshift through the gears, use the engine brake and trailer hand valve, and head for an escape ramp or soft ground.

EWD placement

Early warning devices are the two reflective triangles carried on board and set about four metres behind and in front of a stopped vehicle on the roadway.

Driver vehicle defect report

The written record of faults found during the post-trip inspection; a safety-related defect must be repaired and cleared before the vehicle is dispatched again.

Post-trip air tank drain

Opening the drain valves at the end of the shift removes condensed moisture from the air tanks, protecting valves and brake components from corrosion and freezing.

Trip ticket

The document recording the trip origin and destination, odometer readings, fuel issued, and cargo carried, completed and submitted at the end of the run.
