Hello, Let's say Im going to make a website about some BMW racing driver, is it ok for me to use the BMW logo on that site? Or is it illegal? Thanks!
You should be okay as long as you don't use it in a fraudulent manner as in pretending you are associated with the company or are acting on the company's behalf.
I would go to the BMW corporate site and look for their terms specifically. They usually have media kits and will have the logos there for you to download and specify when/where you can use them. It's better to do it right rather than get them ticked off at you and sue you or, worse, file a DMCA with the search engines and get your site banned or flagged as a copyright violator in the search engines.
