Chauffeur License Vehicle Operation & Maintenance 2 — Questions and Answers
Question 1: A chauffeur notices the power steering feels heavier than usual. What is the most likely cause?
- Low power steering fluid (Correct answer)
- Overinflated tires
- Worn brake pads
- Loose serpentine belt tension
Correct answer: Low power steering fluid
Low power steering fluid reduces hydraulic pressure, making the wheel harder to turn.
Question 2: What does a flashing yellow check engine light typically indicate compared to a steady one?
- A more serious, potentially catalytic-converter-damaging misfire (Correct answer)
- A minor emissions sensor fault
- Low oil pressure only
- The system is running a self-diagnostic test
Correct answer: A more serious, potentially catalytic-converter-damaging misfire
A flashing check engine light signals an active misfire severe enough to damage the catalytic converter and requires immediate attention.
Question 3: When should a chauffeur perform a pre-trip inspection of the limousine?
- Before every trip (Correct answer)
- Once a week
- Only after long trips
- At every oil change interval
Correct answer: Before every trip
A pre-trip inspection before every trip ensures safety systems, lights, fluids, and tires are in proper working order.
Question 4: What is the recommended action when a vehicle's ABS warning light remains on while driving?
- Have the ABS system inspected by a technician promptly (Correct answer)
- Drive normally; it resets after a few miles
- Pump the brakes repeatedly to reset the sensor
- Increase following distance only for that trip
Correct answer: Have the ABS system inspected by a technician promptly
A continuously illuminated ABS light means the anti-lock system may be disabled, requiring professional diagnosis before relying on it.
Question 5: Which tire condition is most dangerous at highway speeds for a chauffeur vehicle?
- A tire with tread depth below 2/32 of an inch (Correct answer)
- A tire inflated 5 PSI above recommended
- A tire with minor sidewall scuffing
- A tire that is two years old but unworn
Correct answer: A tire with tread depth below 2/32 of an inch
Tread below 2/32 inch (the legal minimum) severely reduces wet-road grip and blowout resistance at highway speeds.
Question 6: A chauffeur smells burning rubber inside the vehicle cabin. What should they do first?
- Safely pull off the road, stop the vehicle, and investigate the source (Correct answer)
- Open windows and continue to the destination
- Accelerate to clear the smell faster
- Check the air conditioning filter
Correct answer: Safely pull off the road, stop the vehicle, and investigate the source
A burning rubber smell can indicate a brake, belt, or tire issue that could lead to a fire or loss of control if ignored.
Question 7: How does cold weather typically affect a vehicle's tire pressure?
- Pressure drops approximately 1 PSI for every 10°F decrease in temperature (Correct answer)
- Pressure increases as tires contract in the cold
- Cold weather has no measurable effect on tire pressure
- Pressure drops only if tires are already underinflated
Correct answer: Pressure drops approximately 1 PSI for every 10°F decrease in temperature
As air cools it contracts, reducing tire pressure — roughly 1 PSI per 10°F drop — requiring seasonal pressure checks.
