A PHC driver notices the vehicle's headlights are flickering and noticeably dim before starting a shift. What is the correct response?

Answer: Have the lights repaired by a qualified mechanic before resuming hire work

Flickering or dim headlights compromise road safety and must be repaired before the vehicle is used for hire, as the driver has a duty to maintain the vehicle in a roadworthy condition.

Which tyre condition would result in a private hire vehicle FAILING its mandatory LTA inspection?

Answer: Tyres with a tread depth below 1.6 mm

Any tyre with a tread depth below the legal minimum of 1.6 mm is classified as unsafe and will cause the vehicle to fail its mandatory inspection.

How should a PHC driver perform a quick brake check before commencing a shift?

Answer: Press the brake pedal firmly while stationary to check for firmness and any unusual feel

A firm brake pedal when pressed while stationary indicates a healthy brake system; a soft or spongy feel may signal fluid loss or air in the lines, requiring immediate inspection.

A PHC vehicle has a small windscreen crack that does NOT obstruct the driver's line of sight. What is the recommended course of action?

Answer: Monitor the crack and arrange repair promptly before it spreads

Even a crack outside the driver's line of sight should be repaired promptly, as windscreen cracks spread over time and can ultimately compromise structural integrity.

Why is it important for a PHC driver to check the engine oil level regularly?

Answer: To lubricate engine components, reduce heat, and prevent engine damage

Engine oil lubricates moving parts, helps dissipate heat, and prevents metal-on-metal contact; inadequate oil can cause serious and costly engine damage.

Which symptom most strongly suggests that a PHC vehicle's tyres or suspension require immediate professional attention?

Answer: The vehicle consistently pulls to one side when driving on a straight road

A vehicle pulling to one side while driving straight typically indicates uneven tyre pressure, uneven tyre wear, or a wheel alignment problem that must be addressed promptly.
