I'll speak in favor of getting a good traffic attorney. I'm three-for-three getting tickets dismissed by employing Houston's infamous David Sprecher. He charges you the face value of your ticket and makes no guarantees. In the worst case, he got my ticket for speeding + out-of-date registration reduced to just the out-of-date registration. I then paid a $75 fee and walked away a free man. The only other cost is dragging your butt into court in the morning.

If there's a comparable attorney in your area, that's who you want.
