What others have said. The studies are clear that deer hear in the same frequency range as humans. If you can't hear it the deer can't hear it.
Cars and trucks are noisy but deer run in front of them all the time. You can't undo tens of thousands of years of evolution in just a few years. See deer are unpredictable so that the mountain lion, tiger, bear, or whatever don't know which way to go to intercept them. It is what keeps them alive when being chased. They react to cars the same way attempting to avoid them by being unpredictable. That darting behavior is good if you are being chased but bad if what your trying to get away from is traveling in a straight line.
