Truck Lane Restrictions

In October 2009, the Texas Transportation Commission approved expansion of truck lane restrictions along IH 20, IH 30, IH 45 and IH 820, following a traffic study, stakeholder meeting, and three public hearings.   The recently approved restrictions were implemented by TxDOT in 2010.


The Truck Lane Pilot study was completed in 2006.  Based on traffic studies, truck lane restrictions have been shown to improve mobility, safety, and air quality. For a corridor to be eligible to be considered for truck lane restrictions there must be three or more traffic lanes (excluding frontage roads) in each direction and there cannot be left exits.  Truck lane restrictions currently exist along sections of IH 20 in Dallas, Kaufman, and Tarrant Counties; IH 30 in Tarrant County; IH 45 in Dallas and Ellis Counties; and IH 820 in Tarrant County.  In these corridor sections, trucks with three or more axles are prohibited from using the inside left lane, except when passing traffic.

Future Truck Lane Restriction Recommendations for North Texas 
Long-term plans for expanding the network of truck lane restrictions are included in Mobility 2045 Update: The Metropolitan Transportation Plan for the Dallas-Fort Worth Area. See the Mobility Option Chapter and the Mobility 2045 Recommendations Map for truck lane information.
