Which of the following results may be caused by continuing driving when the engine oil pressure warning light is flashing red?

The red warning light with an oil can symbol is the engine oil pressure warning light. It comes on when the pressure in the lubrication system is too low - the oil does not reach the bearings, shafts and pistons. Without a film of oil, metal rubs against metal, the engine quickly overheats, and it may seize. That is why the correct answer is A: serious damage to the engine.

The brakes and the drive transmission mechanisms have their own systems and do not depend on engine oil pressure, so answers B and C are wrong. When this light comes on while you are driving, you pull over as soon as you can do so safely, switch off the engine and check the oil level. If the light is still on after you have topped up the oil, driving on means the risk of a repair costing thousands of PLN.
