Are high gas prices giving you road rage? Well, wait "til you see what's coming.
Prices at the pump currently average $3.89 for a gallon of regular unleaded, up 30 cents in the last month.
But it's already over $4.00 per gallon in many cities - more than double the $1.85 a gallon that prevailed when President Barack Obama took office.
And most analysts are predicting gas prices will go much higher.
The national average gas price should reach $4.25 by the end of April as refiners shift over to more expensive summer blends, Tom Kloza of the Oil Price Information Service told the Wall Street Journal.
As prices shoot through the previous high-water mark of $4.11 in 2008, filling your tank could soon hit you for $75-$90.
And the sky's the limit if Iran decides to block the Strait of Hormuz in retaliation for economic sanctions that go into effect in June.
