TN Code § 40-11-105 (2019)
(a)
(1) When the defendant has been arrested or held to answer for any bailable offense, the defendant is entitled to be admitted to bail by the committing magistrate, by any judge of the circuit or criminal court, or by the clerk of any circuit or criminal court; provided, that if admitted to bail by the clerk of any circuit or criminal court, the defendant has a right to petition the judge of the circuit or criminal court if the defendant feels that the bail set is excessive, and shall be given notice of this fact by the clerk.
(2) The clerk of any circuit or criminal court may only admit the defendant to bail when the judge is not present in the court and the clerk reasonably believes that the judge will not be present within three (3) hours after the defendant has been committed to the county or city jail, following arrest.
(b) Except as provided in subsection (c), in no event may a clerk set the amount of bail in excess of:
(1) One thousand dollars ($1,000) if the defendant is charged with a misdemeanor;
I believe it also applies to the judge. Excessive is excessive, especially for minor traffic offences. $10,000 per for expired tags, and no insurance when they only carry a $50 fine each.
