Most cars would not have any oil pressure until after the engine starts turning because the oil pump is driven mechanically off of the engine.
For the operator to monitor the oil pressure of the engine. If the oil pressure drops below average when running, the engine is in trouble.
Yes. However, the oil pressure switch may be accurate, in which case you have low oil pressure in the engine which can be caused by a faulty oil pump or clogged oil pump screen. Low oil pressure can cause serious damage to the engine. The oil pressure switch is shutting the engine down to prevent any damage. The best thing to do is take the car to a mechanic.
When the engine is running in your car the pressure of the oil activates a switch that is fitted along the oil line. this switch turns of a light that would otherwise be on on the dash of your car whenever the ignition is turned on.

The real key here is "OIL PRESSURE" The car will drive and not be damaged as long as there is enough oil to keep the lubrication system working correctly, usually shown on the dash as oil pressure. The oil level will eventually fall low enough that the oil pump will no longer make pressure and the engine will be completely ruined in less than a minute.
