The Copyright Office stated the ruling would go into effect after 12 months. The exemption will run until 2018, when advocates will have to ask permission to repair their cars again.
Automakers argued against the ruling, taking the stand that the software in modern vehicles has become too advanced for average owners to comprehend and work on. Automakers claim cars are now "mobile computing devices," bringing automobiles and John Deere's tractors under the DMCA's umbrella. Both General Motors and John Deere previously claimed that the software in its machines didn't belong to the owners.
While modern computers and software have made cars safer than ever, hackers have revealed just how easy it can be to remotely take over a vehicle. The exemption will also give owners the ability to check their own cars for security vulnerabilities without visiting a dealership.
