The car running radar parks well more than one mile from Piperton city limits. Tennesse law allows the unit to go a maximum of one mile out of city limits. The unit is about three miles north of the Piperton exit on 385. No Piperton city limit signs on 385. Car is facing north, sitting in the median. He can immediately pull into the south bound lane and “gotcha”. It would seem that a motorist receiving a citation at this point could, with a good attorney, own half the city.
