In Texas, when is it legal to drive on a paved shoulder to pass another vehicle on the right?

Explanation

Under Texas law, you may use the paved shoulder to pass a vehicle on the right in the following situations: (1) The vehicle is making or about to make a left turn; (2) the vehicle is slowing or stopped on the main traveled portion of the roadway; or (3) the vehicle is disabled on the main traveled portion of the roadway. (Never pass on the right by driving off the paved portion of the roadway.) You may also drive on the paved shoulder if necessary to accelerate before you enter the main traveled roadway, to decelerate before making a right turn, or to let another vehicle pass you. Of course, you may drive on the paved shoulder in an emergency or if so directed by official traffic control devices. (Note: In many other US states, it is illegal to drive on the paved shoulder for any reason except in an emergency or as directed by emergency personnel or flag persons. When traveling out of state, always check the local traffic laws.)
