CARB Regulations

What are the CARB Anti-Idling Regulations?

Anti-idling regulations are becoming increasingly important in the heavy-duty trucking market. In an industry that uses high voltage power, it can be challenging to find solutions that protect personnel, property, and the environment. The SAFEX system allows you to meet CARB regulations, as well as ensures proper connection and disconnection of shore power, all while protecting personnel and property.

Prepare Now

California’s CARB is putting regulations in place in order to prepare for a mandatory 480 VAC powering infrastructure that must be in place at all facilities by 2024. CARB indicates that truck diesel-powered reefers represent approximately 25% of total PM2.5 diesel emissions (making reefer pollution #3 after truck and train diesel engines). As a result, CARB will ban truck diesel-powered reefer units starting in 2025, so steps must be taken now to prepare for these changes.

The following timeline shows basic CARB requirements that will impact reefer use over the next few years:


  • All reefers operating in California must register with CARB
  • All new reefers must use refrigerant that is less than 2,200 GWP


  • All facilities that receive reefer trailers/containers must register with CARB


  • All facilities must complete installation of an electric powering infrastructure to support zero-emission reefers


  • All truck/trailer fleets must turn over more than 15% per year from diesel to zero-emission reefers
  • All reefers must use zero-emissions if parked for more than 15 minutes
  • All remaining diesel reefers must meet US EPA Tier 4 emissions standards


  • All new and used reefers must be 100% zero-emission (no diesel engines)
