For most people, a traffic violation simply means a fine. But for poorer people in the US, it could mean being imprisoned.

Presenter Ed Butler talks to Robin Steinberg, CEO of the non-profit Bail Project in Los Angeles, which is aimed at helping accused people stay out of jail while they're awaiting trial.
