Get the green light意思

"Get the green light" is an English idiom that means to receive approval or permission to proceed with something. The phrase comes from the color green being used on traffic lights to indicate that it is safe and legal to proceed.

For example, if you have been waiting for your boss to approve your project, and they finally give you the go-ahead, you could say that you have "gotten the green light" to move forward with your plans.
