Is Robotics and Automation Letters Open Access or Traditional Journal? I recently completed a paper and I am considering applying for the Robotics and Automation Letters (RA-L). Before submission, the paper plaza had a few guidelines which said 


  IEEE Robotics and Automation Letters (RA-L) is a hybrid access journal, allowing either traditional or Open Access ("golden", or author-pays OA) manuscript submission. According to the IEEE policy, you will only be able to select the Open Access option after acceptance, at the time of final submission. By selecting that option, you commit to pay the $1,950 OA fee in order to enable unrestricted public access.


I am confused with what this means? Does it mean that I will only be able to select the Open Access Option? Does it mean that I can choose the traditional option, but in case I prefer Open Access it will only be after acceptance.
"Only" means that you don't have the ability to choose traditional vs Open Access until after acceptance.
