A police officer must have probable cause to make a traffic stop in an DUI investigation.  In Metro Nashville Davidson County’s DUI testing report commonly referred to as a 132 report it lists several reasons for a traffic stop.They are:

  • Crossing center dividing line
  • Failure to obey traffic signals
  • Swerving within the roadway
  • equipment violations such as driving without headlights
  • Speeding
  • Vehicle driving off roadway

The reason for the traffic stop is the first thing an experienced DUI lawyer investigates.
