While you can always rely on sfDon's advice, your picture may suggest other problems.
You mention seeing "clear fluid" on the driveway. Look closely at your power steering reservoir and there appears to be some "red" liquid left. This may indicate you have something other than power steering fluid on the ground. Obviously, the power steering reservoir needs to be filled . . . but perhaps you need to do some more detective work before driving the car.
Assuming your mystery fluid is not water from the cooling system, windshield washer or air conditioning condensation, carefully check your brake fluid reservoir
again. Assuming you have a manual transmission, could you be leaking "clear" brake fluid from your clutch master or slave cylinder? On the same subject, your brake fluid reservoir cap is hardly sealed in your photo and needs attention.
Whatever transmission type is in your vehicle,
could it be the source of your mystery fluid? Although unlikely, it is possible to have uncolored mineral oil in a manual transmission. It is improbable but perhaps possible for auto transmission fluid to lose its red color after many years.. Or, maybe the fluid on your driveway is actually red - but merely looks clear when viewed on the ground?
One last thought about your mystery driveway fluid, could it be clear "fuel?"
Better to be safe than sorry. Best of Luck.
