Gas prices have gained 12 cents this week, as tensions over Iran heat up and oil prices keep moving higher.
The price of unleaded gasoline shot up overnight by 3.5 cents to a nationwide average of $3.647, according to the motorist group AAA. That's the 17th consecutive day of increases.
Since the start of the month, prices have gained nearly 6%. And they're up 11% from the start of the year.
In many parts of the United States, including New York City and parts of California, gas prices are already above $4 per gallon.
