The Palm Beach County Commission is expected to vote Tuesday on an ordinance that would make it easier for drivers to know how much they're are paying for gas. 

Half of the gas stations in Palm Beach County advertise a discounted cash price on the street but charge a higher price at the pump when the customer uses a credit card.

The county proposal would require stations to post the highest price for fuel and those credit and cash prices would have to be the same size and visible from the street.
