For 40 years, UTA has provided free rides in downtown Salt Lake City. You may ride for free on TRAX or fixed-route bus as long as you enter and exit within the boundaries of UTA’s Free Fare Zone, as shown in the map below.
If you begin your ride within the Free Fare Zone and plan to exit outside the Free Fare Zone, you will be required to provide proof of payment. If you board outside the zone and travel into it, you also need to provide proof of payment. If you use an electronic fare card (FAREPAY, Eco Pass, Ed Pass, etc.) within the Free Fare Zone, you must tap on and off. If you do not tap off, you will be charged for the trip.
When boarding a bus within the Free Fare Zone, simply tell the operator that you intend to stay in the Free Fare Zone and you will be allowed to ride free of charge.
