The City of Austin works under a Zone Program.  This allows the Police Department to remove vehicles from major roadways (IH 35, Mo-Pac Expressway, US Hwy 183) that could potentially cause hazards.  Wrecker companies are stationed on these major roadways during rush hour times Monday – Friday from 6am-9am and 4pm-7pm, except for City of Austin Holidays.  If a vehicle is left unattended during this time, the vehicle will be removed immediately.  Any vehicle left unattended on IH-35 will be impounded as a traffic hazard because of the high volume of traffic on this road at any hour.  Otherwise, vehicles left unattended on the roadways that do not pose as a traffic hazard will be tagged as abandoned and impounded after 48 hours, if still on scene.
