A driver's license is a property interest that a state cannot take without due process, yet most licenses are lost through automatic administrative action rather than a court judgment. This article explains the four families of suspension: safety-based, implied consent, debt-based, and collateral. It traces the constitutional framework from Bell v. Burson through Dixon v. Love and Mackey v. Montrym, and explains why pre-deprivation hearings are rare. It walks the administrative hearing that most drivers never request, the deadlines that make it disappear, and the hardship license that keeps people working. It closes with reinstatement, the stacked-suspension trap, and what reform has actually changed.
