What is taking the reins meaning?

"Taking the reins" is a common idiom that means taking control or assuming responsibility for a situation or task. The phrase originates from the literal meaning of controlling a horse by holding onto the reins, which gives the rider control over the animal's direction and speed. To take the reins in a non-literal sense means to take charge of a situation, typically by assuming a leadership role or by becoming actively involved in resolving a problem. It implies a willingness to take charge and responsibility, and may also suggest a readiness to make difficult decisions or take bold action when necessary.
