The San Jose Fire Department received a report of a vehicle crashing into the Santa Teresa DMV office at 180 Martinvale Lane near Santa Teresa Boulevard at about 12:07 p.m., Capt. Cleo Doss said.
The vehicle has also ran over a gas meter, sheared the gas line and caused gas to escape, prompting fire officials to call for a 1-alarm response, Doss said.
Firefighters ordered the DMV office and a couple of adjacent buildings evacuated until the gas could be turned off, Doss said.
The scene was declared under control at 12:38 p.m.
Officials with the DMV say the office will be closed for the rest of the day to make sure the gas smell leaves the building. They say a handful of employees will stay to redirect customers and to help those with simple tasks and those who had appointments.
The driver of the vehicle was removed from the crashed vehicle, treated at the scene and then transported to a hospital, Doss said.
The investigation into the collision and gas leak is to be handled by the California Highway Patrol, since the DMV is on state property, Doss said.
CHP spokesman Chris Falkowski confirmed that the CHP would be investigating the incident.
