The California 149 form, known as the Three Day Pass Exemption Form, plays a crucial role for fleet owners operating vehicles that do not meet the stringent emission reduction requirements set forth by the Truck and Bus Regulation. This temporary pass allows a single vehicle to operate in California for three consecutive days without facing penalties for non-compliance. Each company is permitted only one pass per calendar year, making it essential for fleet managers to plan accordingly. The form requires detailed owner and vehicle information, including the vehicle identification number (VIN), manufacturer, model year, and engine specifications. Additionally, the responsible official must attest to the accuracy of the provided information, ensuring accountability. To obtain this pass, fleet owners must submit the completed form to the California Air Resources Board (ARB) at least three days before the vehicle's intended entry into the state. While there are no mileage restrictions during the exemption period, it is important to note that the pass is only necessary if the vehicle is not already reported under compliance options. Understanding the nuances of this form can help fleet owners navigate California's regulatory landscape more effectively.
