Some major cities issue hundreds of thousands of parking tickets every year. It has been stated that in some cases, they have increased the enforcement of parking laws merely to increase city revenues. If that is the case in your area, you might want to deny them the income from your ticket, if you have a viable defense. It is not impossible to dispute parking tickets. In fact, some jurisdictions are seeing a 30% to 50% success rate among those who do so. But you must remember that a parking ticket is a civil infraction and does not appear on your driving record or increase your insurance rates. If you do not have a defense, it may cost more to fight a parking ticket than it does to pay it. If you do dispute a parking ticket, it is vital to follow the rules carefully. Especially be sure to meet filing deadlines. If you don't, you can be found guilty by default.
