Michigan Becomes 4th State to Allow Self-Driving Cars

As expected, Michigan Gov. Rick Snyder has signed a law that permits developers to evaluate driverless vehicles on public roads. The state joins California, Florida and Nevada in allowing street tests of automated vehicles.

The new law requires a human to occupy the driver's seat, monitor vehicle performance and take control if necessary.

A companion law also signed by Gov. Snyder shields carmakers from civil liability for damages caused by vehicles modified for autonomous operation, unless the damages were the result of a defect in the original vehicle design.
