About Us

Bolex LLC was founded to meet a growing need in the trucking industry — helping drivers and fleets stay compliant with California’s new CARB OBD testing requirements without the hassle of traveling out of state. Based in Cleveland, Ohio, and licensed by the State of California, we provide both in-house and mobile testing services for truck drivers operating across the United States.

We understand that time is money in the trucking business, which is why we’ve designed our process to be quick, efficient, and driver-friendly. Whether you’re an independent owner-operator or managing a large fleet, we bring the test directly to you, saving you downtime and keeping your routes on schedule.

Our $150 flat rate includes a free retest if your truck doesn’t pass the first time, ensuring you can get back on the road with confidence. We take pride in delivering honest, accurate, and professional service, backed by our official California certification and a commitment to helping drivers meet compliance standards with ease.

At Bolex LLC, our mission is simple: keep you moving, keep you compliant, and keep your business running smoothly.
