Officer’s sit in their car at the top of the hill just West of the QT truckstop near I-35 and Pleasant Valley road in the fire station parking lot, or sometimes right across the street from the fire station. It is a 25 mile zone.

There is another one also near I-35 just North of the QT truck stop on Church Road (which is kind of an outer road running along side of I-35). They usually sit on Orchard road enforcing a 35 mile per hour zone that turns into a 45 mile zone (so if you are headed south on church road from Liberty, be sure to slow down to 35!)
