What does it mean if the ignition warning light comes on while you're driving? The oil pressure is low There's an electrical fault The air pressure is low There's a hydraulic fault 9. 19. Why are energy-saving tyres effective? They have a reduced rolling resistance They cost less to produce They have no tread pattern They don't puncture at high speed 10. 16. What should you do before stopping a turbocharged engine? Release the air-suspension valve Allow the engine to idle Select reverse gear Rev the engine sharply 11. 63.

You're driving a three-axle double-deck bus and have the steering turned onto full lock. What should you do to avoid rear tyre scrub? Use the highest gear possible Drive at a very low speed Apply the exhaust brake (retarder) Reduce the pressure in the rear tyres 14. 30. You're driving a double-deck bus. What's the minimum depth of tread required over three-quarters of each tyre's width? 0.8 mm 1 mm 1.6 mm 2 mm 15. 8. Why are frequent tyre checks advisable on a tri-axle double-deck vehicle? These tyres are more likely to deflate Punctures can be difficult to detect Blow-outs are more common on these vehicles Tyre pressures are difficult to maintain 16. 71. In very cold weather, moisture can freeze in your vehicle's air storage tanks. What can you do to help prevent this from happening? Cover the air tanks with a blanket Drain the tanks daily Use the brakes frequently Pump the brakes 17. 48. On your daily walk-round check, you see that one front tyre is more than 10 years old. What should you do before using the vehicle? Check the tyre pressure Get the tyre replaced Record the tyre's age on your log Check the tread depth 18. 46. What would be illegal? Using different makes of tyre on the same axle Using a tyre with a recut tread Using a tyre with a tread depth of 1.3 mm Using a tyre with exposed ply or cord 19. 81. You're driving a six-wheeled double-deck bus. What do you need to know about punctures on the rear tyres? They're much easier to detect They're more likely to happen They're more difficult to detect They're less likely to happen 20. 3. What happens to diesel fuel when it gets hot? It expands It liquefies It shrinks It waxes 21. 41. You're checking your vehicle. What should you do if you discover an air leak in the braking system? Drive slowly to the nearest garage Check the leak from time to time on your journey Leave the vehicle parked and report the fault immediately Start your journey and report the fault on your return 22. 56. What do the codes shown on the side walls of bus and lorry tyres refer to? Tread pattern Minimum temperature Maximum load Running pressure 23. 9. You're driving along a motorway. What should you do if the air-pressure warning device starts to operate? Stop immediately in the lane you're in Continue slowly to the next service area Stop on the hard shoulder as soon as possible Leave the motorway at the next exit 24. 50. Why do air tanks on brake systems need to be drained? To remove excess coolant To remove rain water that's seeped into the system To remove any oil leaks that collect here To remove moisture drawn in from the atmosphere 25. 39. What can you add to diesel fuel to prevent it from becoming less effective at low temperatures? Anti-freeze Anti-waxing additives Petrol Paraffin 26. 12. You're checking your vehicle's tyres before starting a long motorway journey. What check should be made on each tyre? Air pressure Tracking Valve clearance Tyre profile 27. 31. What could happen if you overfill your engine with oil? The handling may improve Exhaust emissions could be reduced Some gaskets might be damaged You could wait longer before the next service 28. 77. When should the driver of a coach wear gloves? To load and stow passengers' luggage To operate a lift for disabled passengers To handle the fares To top up the oil or water levels 29. 13. Why should your engine oil be changed at the recommended intervals? To reduce friction and wear For better steering control To prevent oil leaks To improve clutch wear 30. 51. The bus you're driving is fitted with automatic transmission. When would you use kickdown? When stopping in an emergency When changing to a higher gear When driving at slow speed When needing brisk acceleration 31. 2. What's the purpose of the oil filter? To prevent the engine from overheating To give better fuel consumption To prevent the engine from over-revving To collect metal particles from the oil 32. 49.

While driving, your engine-oil warning light comes on. Why could it be dangerous to continue driving? The brakes will fail The engine may be damaged You'll need to have the vehicle serviced You'll need to replace the carburettor 36. 15. Where does a high-pressure fuel injector deliver fuel? Into the carburettors Into the combustion chamber Into the manifold Into the crankcase 37. 80. Some buses have different-sized wheels on the front and rear. What do you need to be aware of when driving at high speeds on long journeys? The tyres on the larger wheels are more likely to overheat The tyres on the smaller wheels are more likely to overheat The tyres on the larger wheels are more likely to lose pressure The tyres on the smaller wheels are more likely to lose pressure 38. 62.
