Saudi Heavy Vehicle Theory study plan

List every Saudi traffic-law category that applies to heavy vehicles (speed limits by road class, lane use, overtaking bans, parking), and state the numeric limit for each in a single reference table.

Identify and correctly name 40 Saudi road signs and markings, including those most often misread (mandatory direction, no-overtaking, weight-limit, height-limit, axle-load, danger warning, and temporary construction signs).

Explain the penalty structure for heavy-vehicle offences (speeding, overloading, expired inspection, unsecured load) and rank them from most to least likely to trigger an immediate driving ban.

Solve 20 written scenario questions on right-of-way, junctions, roundabouts and sign priority, then review every wrong answer and write the correct rule in one sentence each.

Map Saudi heavy-vehicle licence categories to the vehicle classes they authorise (rigid truck, tractor-trailer, bus, tanker, abnormal load) and state the minimum age and licence history for each.

Define the legal maximum dimensions (width, height, length) for rigid and articulated combinations and explain what an abnormal-load permit changes.

Calculate legal axle and gross weight limits for three worked examples, including a tandem-axle group, and show the arithmetic step by step.

Explain the difference between design gross vehicle weight, permissible payload and actual laden weight, and why overloading is both a safety and a legal failure.

Answer 25 mixed questions on licence categories and load limits, and log every error with the correct figure.

Trace the path of compressed air from compressor through governor, reservoirs, drain valves and safety valve to the brake chambers, and explain what each component does.

Explain the function of the foot valve, relay valve, quick-release valve and spring (parking) brake, and describe what happens when system pressure falls below the warning threshold.

Diagnose five written air-brake faults (slow build-up, pressure loss with engine off, dragging brake, uneven braking, low-pressure warning that never clears) and state the correct driver action for each.

Describe the correct procedure for a static brake test and a low-speed running brake test before a loaded trip, listing the pass criteria.

Describe how brake fade develops on a long descent and the correct use of gears, engine braking and retarder to control speed without overheating the brakes.

Build a written pre-trip inspection checklist covering tyres and pressures, wheel nuts, brake and air lines, lights, mirrors, couplings, fifth wheel, load security and emergency equipment, in walk-around order.

Explain the Saudi periodic inspection (periodic technical inspection) requirements for heavy vehicles, including what is checked, how often, and the consequences of an expired certificate.

List the documents a heavy-vehicle driver must carry and keep valid (licence, registration, inspection certificate, insurance, permit where applicable) and state what happens if one is missing.

Identify ten defects that make a vehicle unroadworthy and must keep it off the road, and distinguish them from ten defects that can be logged and repaired later.

Perform and record a full inspection of a real or simulated vehicle in under 30 minutes using your checklist.

Calculate safe following distance for a 40-tonne combination at 60, 80 and 90 km/h using a four-second gap, and compare the result with the two-second gap used for cars.

Explain how total stopping distance splits into perception, reaction and braking distance, and how load, road surface and gradient change each part.

State the correct speed choice for heavy vehicles in rain, dust storms, fog, night driving and on descending grades, and justify each with a stopping-distance argument.

Apply the load-securing principles of lashing angle, number of tie-downs, aggregate lashing capacity and friction to two worked examples (steel coils and palletised cargo).

Explain correct weight distribution across axles, the effect of a high or rear-biased centre of gravity on stability and steering, and how to detect an overloaded axle before departure.

Scan 15 written hazard scenarios (blind junction, pedestrian behind a reversing truck, cyclist in a blind spot, stopped school bus, animal on a rural road) and name the hazard, the earliest cue and the planned response for each.

Describe the blind-spot zones around a heavy vehicle and the correct mirror sequence for a lane change, turn and reverse.

Explain the correct response to a tyre blowout, brake failure, aquaplaning, jackknife onset and a steering pull, including what not to do in each case.

Describe defensive strategies for vulnerable road users, including turning-vehicle cyclist risk, and for night and low-visibility driving.

Complete 20 hazard-perception questions under a two-minute-per-question limit and review every miss for the cue that was overlooked.

Explain the effects of fatigue on reaction time, attention and judgement, and apply the recommended countermeasures (rest breaks, sleep, shift planning, recognising micro-sleep warning signs).

State the legal position and real-world consequences of alcohol and drug use for heavy-vehicle drivers, including how impairment interacts with long shifts and night work.

List the medical and fitness conditions that affect heavy-vehicle driving and the driver's duty to report a change in fitness.

Describe the correct first-response sequence at an accident scene: secure the scene, warn traffic, check for injuries, call emergency services, avoid moving casualties unless there is fire risk, and exchange details.

Explain how and when to report an accident or incident to the employer, police and insurer, and what evidence and records to preserve.

Complete two full-length timed mock exams across all nine domains and record the score for each domain separately.

Re-study only the domains scoring below 80%, using the error log from weeks 1 to 7 to target the specific rules and figures that were missed.

Recite from memory the heavy-vehicle speed limits, axle-load limits, following-distance figures, air-pressure warning threshold and pre-trip checklist sequence.

Re-run one full pre-trip inspection and one brake test procedure aloud, timing each to exam pace.

Answer 30 rapid-fire mixed questions with no more than two errors, then stop studying and rest before the test date.
