Waymo opened its instructions with a toll-free, 24-hour hotline number. The company is encouraging emergency responders to call it -- or press the Live Help button on the ceiling of the vehicle --- so they can talk to one of its trained specialists who can help them find the best solution for the situation at hand.

Waymo has also included an overview of its cars' parts and capabilities, along with instructions on how first responders can make sure the car doesn't drive away while they're breaking a window. It contains details on how to disable self-driving mode, how to switch the vehicle off completely, as well as how to disable electric power or disconnect the battery if responders can't get inside the car at all. Once the vehicle is switched off, Waymo says it can be towed just like any other vehicle.

Company spokesperson Alexis Georgeson explained that since the technology is new "part of that commitment means working closely with public safety officials and first responders so they understand how [its] vehicles work and can be prepared for any situation on the road including emergencies, collisions and other scenarios where there is no Waymo employee in the driverless car."
