Somewhat commonly. Oklahoma and Texas have a strong tendency to set down at least three sets of rumble strips on approach to a traffic light, stop, give_way or the side way of a T intersection when the speed limit is 55 or faster. Oklahoma Turnpike Authority also uses rumble strips to warn of the toll plaza on the state's only undivided turnpike. > I agree about the signs though.
