The head of the Texas agency that regulates the oil and gas industry is urging people to wait three or four days to fill their cars and trucks with gasoline if they can.

Railroad Commissioner Ryan Sitton said Thursday that people are panicking and that’s causing a run on gas and empty fuel pumps.

He says there is plenty of gas in Houston and elsewhere, but there are logistical problems of making sure all of the stations are getting it.

He says he doesn’t think it will be an issue a week from now as long as people stay calm and fill up their tanks as they normally would.
