The surge in prices over the past month has been triggered by rising oil prices the result of an Iranian blockade of the Strait of Hormuz.

Also, gas prices are starting to climb just as the spring break travel season gets underway.

This time a month ago, gas prices averaged $2.95 per gallon.

The last time average gas prices averaged above $4 per gallon was August 2022, as average gas prices remained above $4 for the months following the start of the Ukraine/Russia conflict.
