Hong Kong LGV Theory Test flashcards

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

Double white line system

A solid white line on your side means you must not cross or straddle it, except to pass a stationary obstruction or enter premises; a broken line on your side permits overtaking when safe.

Yellow box junction

A yellow criss-cross marking at a junction. You must not enter the box unless your exit is clear, except when turning right and only blocked by oncoming traffic.

Amber traffic signal

A steady amber light means stop, unless it is unsafe to do so because you are too close to the stop line to stop safely.

Zig-zag crossing markings

Markings on the approach to a pedestrian crossing. Parking and overtaking the leading vehicle within the zig-zag area are prohibited.

Two-second rule

In dry conditions, leave at least two seconds between you and the vehicle ahead. Double it to four seconds in rain and increase further at night.

Hong Kong urban speed limit

Unless signed otherwise, the speed limit in built-up urban areas of Hong Kong is 50 km/h. Higher limits apply only where signs show them.

Overtaking on the left

In Hong Kong, overtake on the right. Overtaking on the left is permitted only where traffic is moving in queues in lanes or the vehicle ahead is turning right.

Roundabout give-way rule

At a roundabout, give way to traffic already on the roundabout approaching from your right. Signal left to leave, and right only to change lanes.

Child restraint requirement

Passengers under 1.35 m in height must use an appropriate child restraint where one is available. Seat belts are compulsory for all occupants where fitted.

System of car control

A sequence for approaching hazards: course, mirror and signal, manoeuvre, position and speed, look, assess, decide, and act.

Stopping distance and speed

Braking distance increases roughly with the square of speed, so doubling speed approximately quadruples the distance needed to stop.

Aquaplaning response

When tyres lose contact with a wet road, ease off the accelerator and avoid hard braking or sharp steering until grip returns.

HGV blind spots

A heavy goods vehicle has large blind spots along both sides and behind. If you cannot see the driver's mirrors, the driver cannot see you.

Crosswind risk

High-sided goods vehicles and vehicles towing trailers are most affected by strong crosswinds. Reduce speed and allow extra clearance when passing them.

Daily walk-round check

Before driving, check tyres, lights and indicators, mirrors, windscreen and wipers, fluid levels, and that the load is secure.

Gross vehicle weight

The maximum permitted weight of the vehicle plus its load. Exceeding it is an offence and affects braking, steering, and tyre safety.

Load securing principle

The load must be restrained so it cannot move or fall. Use rated straps, chains, or bars, and recheck tension after the first few kilometres.

Tyre pressure check

Check tyre pressures when cold. Under-inflation increases heat build-up, fuel use, and the risk of a blowout, especially under load.

Fifth-wheel coupling check

Confirm the coupling is fully engaged, the security pin is in place, air lines are connected, and landing legs are raised before moving off.

Engine braking on descents

Select a lower gear before a long descent and use engine braking. Relying on service brakes alone can cause fade and loss of control.

Load centre of gravity

Keep the centre of gravity low and forward of the rear axle where possible. An overloaded rear axle reduces steering grip and lengthens stopping distance.

Driver liability for loads

The driver is responsible for load security and can be held liable for an insecure load even if another person loaded the vehicle.

Reversing a large goods vehicle

Use a banksman where possible, check both mirrors and blind spots, and stop immediately if you lose sight of the guide.

Driving without insurance

Using a vehicle without valid third-party insurance is an offence carrying fines, licence endorsement, and possible disqualification.

Hand-held phone offence

Using a hand-held mobile phone or similar device while driving is an offence, including when stationary in traffic.

Failure to stop after accident

After an accident involving injury or damage, you must stop, give your details, and report to police where required. Failing to do so is an offence.

Penalty points totting-up

Penalty points accumulate on your licence. Reaching the prescribed threshold within the specified period can lead to disqualification.

Motorway breakdown procedure

Move to the hard shoulder, switch on hazard lights, exit on the left away from traffic, wait behind the barrier, and call for assistance.

Tyre burst response

Hold the steering wheel firmly, ease off the accelerator, and let the vehicle slow gradually. Do not brake hard or steer sharply.

Warning triangle placement

On a normal road, place a warning triangle at least 45 m behind the vehicle where safe. Never use one on a motorway hard shoulder.

Hong Kong drink-drive limit

The legal limit is 50 mg of alcohol per 100 ml of blood, equivalent to 22 micrograms per 100 ml of breath.

Fatigue countermeasure

Signs of fatigue include yawning, heavy eyes, and drifting lane position. Stop safely and rest; caffeine is only a short-term aid.
