How long does a person stay in jail for not paying their speeding fines?

The time you stay in jail varies with the crime and/or fines that are imposed. If you are behind on child support, the length of jail time can vary from 6 months to 1 year. If you did not pay fines for a traffic ticket, there may be no jail time depending on the violation, and the case is sent to collections and your license is suspended or revoked.
