Today I saw their truck on Hwy 6 heading to CS and notice that they ignored the "left lane for passing only" signs which is state law. They drove the whole distance in the left lane. Also, as we exited on Texas Avenue just before Harvey Mitchell Pkwy, a school bus which was stopped, the red lights on, it's stop sign out, picking up kids, the McCaffety truck drove right on by, never stopped. Isn't that a law? Last digits of the license plate is 5891. The driver may need to go back to driver's ed.
