A one of its kind delivery van has been granted permission to test-run on US roads.

A company named Nuro in the United States has designed a self-driving vehicle with no basic human controls such as pedals, steering wheels or side-view mirrors, the van will act as a delivery vehicle and has been granted permission to test on US roads.

The designed vehicle is Nuro’s second generation, which it is calling R2. Reportedly, the vehicle will be tested in Houston, Texas and if successful its operation will be expanded to other cities.

This is considered as the first exemption to a rule requiring vehicles to have controls for human operators.

Most of the regulations for testing vehicles demand features that let a driver to safely take control of the vehicles.

Nuro's co-founder Dave Ferguson hailed the development of self-driving van as a "milestone for the industry".

"Moving forward, we must modernize the existing regulations that never envisioned a vehicle without a driver or occupants, and everyone in the industry must work to ensure self-driving technology is tested and deployed in the safest possible vehicles," he wrote in a blog post.

The vehicle has been designed to operate with a driver or passenger. It has no windscreens or side-view mirrors, but the rearview camera will be functional all the time, the vehicle has an egg-shaped frame that is compact and smaller than most cars in the US.
