SALT LAKE CITY — Parking in Salt Lake City is free until technical difficulties with metered stalls are fixed.

Parking-meter enforcement has been suspended until problems that spread throughout the Salt Lake City parking system have been fixed, according to a news release from the Salt Lake City mayor's office. Until then, cars need to follow the Saturday policy of free parking for two hours.

Salt Lake parking officials became aware of the problems Friday evening. People were having a hard time paying for parking, specifically with credit and debit cards, according to Art Raymond, spokesman for the mayor's office.

Metered-enforcement was suspended when city officials realized the problem was widespread. Technical teams and equipment vendors are working to figure out what caused the failures, which may have been triggered or made worse by the hot weather.

"It's too early to say definitively that that was at the heart of the issue, but it's one of the things that we're looking into," Raymond said.

City officials will give the public two to three days' notice before restoring the normal pay meters.
