Gas hits $4 on average in US

The average price of standard gas in the U.S. hit $4 as of Tuesday morning, after hovering right under the dollar mark for about a week.

This is up by over a dollar from a month ago after the onset of the Iran conflict at the end of February spiked fuel prices. The average price of premium gas was at $4.90 and the average price of diesel was sitting at $5.45 in the U.S. on Tuesday morning, according to AAA.
