A California-based tech company has got the green light today to move forward a new line of autonomous vehicles that will soon hit Houston streets.

Nuro, which has a few self-driving delivery pilot programs across Houston, has been granted its exemption petition from the United States Department of Transportation's National Highway Traffic Safety Administration. This move is a first for DOT, and it allows Nuro to roll out its vehicles on public roads without the features of traditional, passenger-carrying vehicles — like side mirrors or windshields, for instance.

"Since this is a low-speed self-driving delivery vehicle, certain features that the Department traditionally required – such as mirrors and windshield for vehicles carrying drivers – no longer make sense," says U.S. Secretary of Transportation Elaine L. Chao in a news release.

Now, with this permission, Nuro has unveiled its newest model — the R2. The new model is more narrow than the R1, and has 65 percent more climate-controlled space for its food deliveries. The vehicle also has new safety features, like 360-degree vision using lidar, radar, and cameras and even has a pedestrian-protecting feature that enables the car to collapse on impact.

"We founded Nuro on the belief that we could reimagine, design, and develop an autonomous vehicle that would make the world a safer place," says Nuro co-founder and president, Dave Ferguson, in a release. "Our second-generation vehicle will advance our goal of transforming local commerce, and we are gratified that the Department of Transportation, under Secretary Chao's leadership, is promoting public safety and providing regulatory certainty for the self-driving industry."

The R2 models are being assembled in the U.S. with Nuro's partner, Roush Enterprises, which is based in Michigan. Per the NHTSA announcement, Nuro can deploy up to 5,000 R2 vehicles during the two-year exemption period. According to the DOT release, the organization will be monitoring Nuro's work throughout those two years.

"NHTSA is dedicated to facilitating the safe testing and deployment of advanced vehicle technologies, including innovative vehicle designs, which hold great promise for future safety improvements," says NHTSA Acting Administrator James Owens in the release. "As always, we will not hesitate to use defect authority to protect public safety as necessary."

Nuro currently has three pilot programs — all of which were announced last year. The company is working with Domino's, Kroger, and Walmart on food and grocery deliveries in six Houston ZIP codes. Since entering the Houston market, Nuro has been using its fleet of self-driving Prius vehicles to research and map the city's roads.

With this permission granted from DOT, Nuro can start making deliveries using its R2 fleet with its three retail and restaurant partners.

"Today's decision shows that 'exemption' can mean more safety," says Ferguson. "Our world-class team solved countless novel problems to create this design, and, after extensive modeling, research, and testing, created a vehicle unlike any other on the road today."
