With the Fourth of July holiday just around the corner, motorists can expect to pay more at the pump this year. Gas prices are expected to be the highest on Independence Day in six years.

Violence in Iraq has called into question the stability of supply, and North American oil prices have advanced by only a few pennies, but the fear of what could happen next is the real concern.

If the exports were to fall victim to violence, the prices could increase even more, but with U.S. oil production as high as it's been since 1986, gasoline will still be well-supplied in all states during the holiday.

But not everyone says gas prices will affect their holiday travel plans. 

"The high prices wouldn't stop us from traveling over the holiday," said Kandice Pack, a local resident who was filling up Monday. "We weren't planning on traveling regardless though. We're having people come to our house instead."

Even with the current rise in prices, the average U.S. gas price for the first half of 2014 was the cheapest in the last four years.

The average price per gallon in the state of Texas according to GasBuddy.com Monday was $3.49, $0.12 higher than South Carolina, the state with the lowest average price.

In Stephenvile, the lowest reported price sat at $3.39 per gallon and the highest price reported was $3.49.
