ACTION ALERT: Help us get SB 210 passed – contact your Assemblymember now!

BREAKING: SB 210 just cleared the Assembly Appropriations Committee and heads to the Assembly floor. Will you help us get it passed?

The fight isn’t over: Some polluter lobbies are opposing this common-sense bill, so we need your help to pass the bill on the Assembly floor!

SB 210, by Senator Connie Leyva (D-Chino) is an important opportunity to prevent thousands of tons of harmful pollutants emitted into our air by heavy-duty diesel trucks.

SB 210 establishes emissions-control inspection and maintenance requirements for diesel trucks weighing more than 14,000 pounds, bringing the hundreds of thousands of these big-rigs on California’s roads closer in line with the smog-check requirements imposed on passenger vehicles since 1984.

Contact your Assemblymember and urge them to vote yes on SB 210 today!

Help us put an end to this!

VOTE YES ON SB 210 (Leyva)




  • Heavy-duty trucks currently do not have a comprehensive inspection and maintenance requirement like the Smog Check program for cars;
  • Many heavy-duty vehicles operate with malfunctioning emissions controls, leading to emissions that are up to almost 10 times engine certification standards;
  • Heavy-duty diesel trucks operating in California account for 82% of diesel particulate matter (PM 2.5), a carcinogenic and toxic air contaminant, and 58% of the harmful oxides of nitrogen (NOx) emissions from mobile sources;
  • Over 90 percent of Californians live in areas impacted by unhealthy air, and the transportation sector is by far the leading source.

Solution – SB 210 would:

  • Establish a Heavy-Duty Vehicle Inspections and Maintenance Program to ensure timely repairs that are needed to reduce emissions of harmful pollutants;
  • Level the playing field for law- abiding truck owners and operators by requiring multiple state agencies to collaborate on an enforceable system;
  • Build in legislative oversight and accountability.
