I don't mean to turn this into an argument over the quality of Texas' driving test, just point out that I, too, hold a Texas license and it is my first license. The driving test consisted of approximately two hours of driving near my local DPS office. I had to go through different types of intersections, parallel park, merge onto the freeway, make legal U-turns, signal appropriately (which is to say, all of the time, and is a skill that apparently didn't stick with most of my fellow drivers), stop at the appropriate spot, and so on.

My original point was that if you gave the DPS clerk a French license, you didn't have to do any of that because Texas considers it a license transfer.
