FLAGSTAFF - Drivers busted by photo-enforcement cameras along state highways in northern Arizona's Coconino County will have to pay to challenge speeding tickets.

Coconino County Justice Courts will charge $20 extra when drivers challenge or ignore their tickets.

The only way for drivers to avoid the extra fee is to pay the ticket without question.

The court has yet to process any citations, but two mobile speed-enforcement cameras are being placed on major highways in the area, including Intestates 17 and 40.

Last year, the court processed 12,300 traffic-related tickets in Coconino County.

The new fee comes as state lawmakers weigh whether to toss out Arizona's controversial new statewide photo-enforcement program.
