What roadside tests could be done if the low oil pressure warning light comes on when driving?
Pull over and park when it is safe to do so. Turn engine off. If
you are not a mechanic call for help. Otherwise open the hood, wait
a couple minutes, pull engine oil dipstick. Take notice of engine
oil level reading on dipstick. If the dipstick reading shows
nothing, do not drive any further until you can add oil. If the
dipstick shows you have oil, you may want to have your car towed
home. If you continue to drive the vehicle with the low oil
pressure light on you may destroy the engine.
