Gas prices continue to rise in Texas as global tensions — including the ongoing conflict involving Iran — continue to push up crude oil costs.
Nationally, prices are also climbing. As of Wednesday, the average price for a gallon of regular gasoline was $4.08, according to AAA.

A line graph shows the sharp increase, with prices rising from $2.98 on Feb. 26 to $3.98 on March 26.
