Aurora Innovation and Kodiak AI have received a five-year federal exemption from a rule that required truck drivers to place reflective warning triangles on the road within 10 minutes of a breakdown. For self-driving trucks, that requirement was impossible to meet without a human on board, and it had become a major obstacle to commercialization. Aurora had previously sued federal safety regulators over the mandate, escalating to the District of Columbia Court of Appeals after an initial request was denied.

The Federal Motor Carrier Safety Administration now allows autonomous truck developers to replace roadside warning devices with cab-mounted warning beacons. Aurora's head of government relations called the beacons a "critical, 21st-century solution" that alerts other road users without putting a person in harm's way. Kodiak's vice president of external affairs said the exemption will help "usher in an autonomous era of freight movement on U.S. roads."

The decision removes a key regulatory barrier for driverless freight, though questions remain about whether the beacons could become standard equipment across the broader trucking industry. The source also noted other mobility deals this week, including Waymo's $5 billion debt financing and Uber's $2.3 billion acquisition of ezCater, but those are separate from the trucking exemption.
