The speed limit on US Highway 175 East and West bound varies (70 MPH down to 30-35 MPH) as you travel along rural areas and then rather suddenly into small towns, usually without much, if any warning. Some of the areas along the highway, before entering a town, having warning signs, i.e. there is a speed limit sign ahead forewarning you that the speed limit is about to change and what that speed limit will be (so you have two chances to reduce your speed). Without driving the 70 or so miles back from Dallas to Eustace, I do not recall ever seeing any such warning sign (they may be there and I was daydreaming?) nor the fact the speed limit changed from 70 to 55. I was ticketed for doing 67 in a 55 MPH zone as I came around a curve into Eustace…heading north West on US 175 towards Kaufman and Dallas. Eustace ticket prices are out of site…$185 for 11-15 miles over the speed limit in my case. In reviewing the latest annual Eustace city budget (October 2011 to September 2012), it is very obvious that the city derives the majority of its city budget from fines ($210,500). That same total budget for the city shows $448,682.32 of expenses of which $224,054 is for various police expenses (50%). So it is pretty obvious that they are a speed trap. The Eustace Police department only costs the city about $13,554 ($224,054-$210,500) a year. The difference is made up in property and sales taxes. If someone else has a better evaluation, let me hear from you.
