Nevada drivers could soon be sharing the road with vehicles that don't need them.

Department of Motor Vehicles officials say they've issued Google the first US license to test self-driving cars on public streets.

Nevada officials said on Monday that demonstrations on the Las Vegas Strip and in Carson City helped show that the company was ready to move the autonomous cars into the next stage of development.

Self-driving vehicle technology works like auto-pilot to guide a car - in this case a modified Prius - with little or no intervention from a human operator.

Nevada's regulations require two people in the test cars at all times.

A DMV official said the cars will display red plates and an infinity symbol to represent their status as vehicles of the future. - Sapa-AP
