Show the correct answer
Correct answer
A. Stop the vehicle and switch off the engine.
Explanation
The question is about the red warning light for the coolant temperature, which has come on while you are driving. You must stop the vehicle and switch off the engine - answer A.
The Road Traffic Act requires a vehicle to be maintained in such a way that using it does not endanger the safety of the people travelling in it or of other road users. The red temperature warning light means that the engine is overheating - for example because of a coolant leak, a broken water pump or a broken fan. Driving on, even more slowly (answer B), risks the engine seizing or damage to the cylinder head gasket, and accelerating (answer C) will only make the engine overheat faster. You stop in a safe place and switch off the engine. You do not unscrew the cap of the expansion tank until the system has cooled down - hot coolant under pressure can burn you.
