You're probably thinking about what other road users are doing (causing mishap), as long as you keep to your lane, signal right, wait if there's a buildup, the lights will eventually go red, in which you can go as your path will more than likely be clear.
Edit when I say they'll go red and you'll go, it's not illegal, you're already committed, go to flow.

Same rules apply, learn about the filter arrows too. Green means go, amber means proceed if safe.
