I have to say that some of the questions on the practice tests were freebies, like what does a "No U-Turn" sign mean? In fact, there ought to be a few key questions on each test that are automatic fails, like under what circumstances you can mow down pedestrians and blind people.
Two days before my appointment at the DMV, I decided to take a few more practice tests - and failed 14 out of 18. These questions were exponentially harder: What is a crossbuck sign? (It's the X-shaped railroad crossing sign.) How many classes of mopeds are there? (Three.) What does a pentagonal sign mean? (School.) The average California driver would know "pentagonal" means five-sided?
I was in full-scale panic mode the morning of the test. Fortunately, the questions were of the type on my first set of practice tests and I got a perfect score. (What I couldn't do was work the test machine.)
Well, theoretically, I have a Real ID on its way to me and I will hopefully be dead (or not driving) the next time my license expires. It's all I can hope for.
