Rental & Leasing
CARB & DOT Compliance
Every trailer in our fleet meets California Air Resources Board standards. Clean air, zero surprises.
Overview
What is CARB compliance?
The regulations and standards set forth by the California Air Resources Board (CARB). As an agency dedicated to combating air pollution in California, CARB oversees emissions from a variety of sources including vehicles, engines, fuels, and consumer products.
All Sonsray rental and lease trailers are inspected, certified, and maintained to current CARB standards before leaving our lots — so you stay compliant without the paperwork.
Importance of Compliance
Compliance is mandatory
For manufacturers, businesses, and individuals who produce, sell, or operate emissions-producing products in California. Adherence ensures reduced air pollution and promotes public health by limiting pollutants like nitrogen oxides (NOx), particulate matter (PM), hydrocarbons (HC), and carbon monoxide (CO).
Non-compliance can result in significant fines, vehicle impoundment, and suspension of operating permits. Our fleet keeps you covered from day one.

CARB Compliance Areas
Meet California's air quality standards across five key areas that apply to every vehicle in our fleet.
Emissions Standards
Emission limits are set for various pollutants crucial for vehicles and equipment to operate legally within California.
Certification
Manufacturers must obtain CARB certification, proving products meet necessary standards through rigorous testing.
Engine Technology
Vehicles and equipment must incorporate catalytic converters, diesel particulate filters, and other emissions-control systems.
Fuel Quality
Fuel standards ensure reduced combustion emissions, encouraging the use of cleaner and lower-carbon alternatives.
Onboard Diagnostics (OBD)
Vehicles must have OBD systems installed to continuously monitor and report on their emissions performance.
Heavy-Duty Vehicle Regulations
CARB has specific regulations for heavy-duty vehicles, including trucks, buses, and off-road equipment like reefer trailers. Requirements include engine upgrades, retrofitting, or replacement to meet stricter emission standards. Every unit in our rental fleet is fully certified and maintained to current CARB specifications.
Penalties & Oversight
Enforcement
CARB enforces compliance through inspections, emissions testing, and penalties for non-compliance. Businesses and individuals must ensure vehicles and equipment meet CARB requirements to avoid fines and operational consequences.
