(UNDATED) - Gas prices nearing four dollars a gallon in Indiana.
Pump prices have risen steadily and are at $3.89 a gallon in many places.
Greg Seiter with Triple-A Hoosier Motor Club says the price of crude oil continues to rise as unrest continues in the Middle East.
Seiter says that unrest is coming at a poor time for motorists because the formulation for gasoline changes with warmer weather and more people are hitting the road as spring turns to summer.
Seiter says it's hard to predict when prices will either stop increasing or fall, but he expects there to be a ceiling at some point.
