Vehicle technology questions for the Turkish driving test

Correct answer: C) With the engine off and the car on level ground

For an accurate reading, switch off the engine, park on level ground and check with the dipstick.

Correct answer: B) Alternator

When the engine is running, the alternator produces electricity and charges the battery.

Correct answer: B) Low coolant in the radiator

Low coolant, or a faulty thermostat or fan, makes the engine overheat.

Correct answer: B) To stop the wheels locking under sudden braking

ABS stops the wheels locking when you brake hard, so you can still steer while braking.

Correct answer: B) Stop in a safe place and switch off the engine

This is the oil pressure warning light. Driving on with low oil pressure seriously damages the engine. Stop safely and switch off the engine.

Correct answer: B) The charging system is not charging the battery

This is the battery (charging) warning light. If it is on with the engine running, the alternator may not be charging the battery, often because of the alternator belt or the alternator itself.

Correct answer: B) The engine is overheating

This is the coolant temperature warning light: the engine is overheating. Stop safely, and never open the radiator cap while the engine is hot.

Correct answer: A) Brake fluid is low

The brake warning light comes on when the handbrake is applied. If it stays on with the handbrake released, brake fluid is low or there is a fault in the braking system.

Correct answer: B) Intake - compression - power - exhaust

A four-stroke engine works in the order intake, compression, power (combustion) and exhaust.

Correct answer: B) Pressurised boiling water and steam can spray out and cause burns

When the engine is hot the cooling system is under pressure. Opening the cap can release boiling water and steam and cause serious burns.

Correct answer: C) 4 mm

Winter tyres must have at least 4 mm of tread. For summer tyres the limit is 1.6 mm.

Correct answer: B) To control what enters the combustion chamber and let exhaust gases out

The intake valve controls the entry of the mixture (air in a diesel), and the exhaust valve lets burnt gases out.

Correct answer: A) Traps dirt and foreign matter in the fuel

The fuel filter stops dirt and sediment from reaching the injectors and the fuel system.

Correct answer: D) Cools the hot coolant coming from the engine

The radiator cools the hot water from the engine by passing its heat to the air flowing through it.

Correct answer: B) Avoid high revs and heavy loads until the engine warms up

In a cold engine the oil has not yet reached every part, so do not strain it until it warms up.

Correct answer: C) Between the lower and upper marks

The oil level should be between the min and max marks. Too little and too much are both harmful.

Correct answer: D) Cuts the circuit when too much current flows, protecting the wiring

A fuse blows when too much current flows, cutting the circuit and protecting cables and devices.

Correct answer: B) The clutch parts wear out early

Resting on the pedal keeps the clutch partly engaged, wearing out the clutch plate and bearing early.

Correct answer: B) When the tyres are cold

Air expands as tyres heat up, so measure pressure when they are cold for a correct reading.

Correct answer: C) Switch to low beam

High beam dazzles the oncoming driver. Switch to low beam when a vehicle approaches.

Correct answer: D) Frequent hard acceleration and harsh braking

Sudden acceleration and hard braking waste fuel. Smooth driving saves fuel.

Correct answer: A) Screenwash antifreeze

Without screenwash antifreeze the water freezes in the tank and pipes and you cannot clean the windscreen.

Correct answer: B) The driving wheels

Chains are fitted to the driving wheels, which receive the engine's power, to prevent skidding.
