If it’s not safe, it’s not worth doing

Safety is mission-critical. Whether we’re running a simulation, testing our hardware or software, or putting our trucks on the road, we hold ourselves and each other to the highest safety standards at all times.

Operational Safety

While our engineers build safety into all of our systems, our in-vehicle test teams are responsible for putting theory into practice. That’s why we provide our Vehicle Operators and Right Seat Operators with extensive training including both formal instruction and extensive in-vehicle practice.

Functional Safety

Core to our systems engineering approach is a focus on functional safety. Building functional safety is the process of minimizing both the potential faults of a system as well as the risk that can come from those faults. The goal of our functional safety program is to determine as broad a universe of potential faults as possible, engineer the hardware and software to minimize the risk of those faults occurring, then develop fallback strategies for how to detect and mitigate those faults when they occur.

Behavioral Safety

In a new industry without standardized rules, we hold our self-driving trucks to our own nonnegotiable standard: they must exceed expert human behavioral performance at all times. To ensure that we meet our standard, we’re building our own safety analysis tools and conducting robust, ongoing safety simulations.

The Safety Case

Despite our passion for engineering solutions—and our belief in the promise of self-driving trucks—all of our trucks operate with human safety drivers. That won’t change until we can demonstrate beyond a shadow of a doubt that our system is safer than a human driver across a wide range of critical scenarios.
