There is essentially no restriction on using brake lights and turn signals at the same time, as they both signal actions/intentions that are often used in conjunction with one another. The brake light signals that you are using your brakes and slowing down, and the turn signal shows your intention to turn. As you will usually slow down as you come up to a turn, there will be many situations where both signals will be on at the same time.
