the chief principles of Texas driving as I have inferred them in my 26 months of living in the Lone Star State

At some point during the execution of a right turn, but always before your car is completely out of the road you have been driving on, be sure to come to a full stop.

Merge onto interstate highways at a speed no greater than 35 miles per hour.

Once on the interstate, if you are driving below the speed limit, make sure to stay in the far left lane and never leave it for any reason except to exit.
