Vehicle Idling Restrictions

Information and documents on the vehicle idling restrictions that applies within the jurisdiction of any local government in Texas that has signed a memorandum of agreement with the TCEQ to delegate enforcement to that local government.

This rule limits the idling of heavy-duty vehicles within the jurisdiction of any local government that has signed a Memorandum Of Agreement (MOA) with the TCEQ for the local enforcement of the state's motor vehicle idling limitations.

Latest Changes

On August 8, 2012, the TCEQ adopted a rule revision amending 30 Texas Administrative Code (TAC) 114, Subchapter J, Division 2, the Locally Enforced Motor Vehicle Idling Limitations. This rule revision added an exemption for motor vehicles that have a gross vehicle weight greater than 14,000 pounds and are equipped with a 2008 or newer engine that has been certified by the United States Environmental Protection Agency or a state environmental agency to emit no more than 30 grams of nitrogen oxides (NOX) emissions per hour when idling.

On July 20, 2011, the TCEQ adopted a rule revision amending the Locally Enforced Motor Vehicle Idling Limitations to expand the enforcement period from April 1 - October 31 to allow for year round enforcement, and removed the expired prohibition for drivers using sleeper berths to idle in residential zones, school zones, and near hospitals. The rule revision also added an exemption for armored vehicles. 

Information

Description:

The Locally Enforced Motor Vehicle Idling Limitations rule, which was first established in December 2004, places idling limits on the gasoline and diesel-powered engines of heavy-duty motor vehicles within the jurisdiction of any local government that has signed a MOA with the TCEQ to delegate enforcement of the state's motor vehicle idling limitations to that local government. This rule prohibits any person in the affected local jurisdiction from permitting the primary propulsion engine of a heavy-duty motor vehicle to idle for more than five consecutive minutes when the vehicle is not in motion. The goal of this air quality control program is to lower NOX and other pollutant emissions from fuel combustion by heavy-duty motor vehicles.
