This article studies the unintended consequences of failure‐to‐pay (FTP) drivers' license suspensions. Unlike other traffic enforcement papers that focus on the public benefit to increases in enforcement, we focus on the private returns. Drawing on a unique administrative data set and institutional features that result in as‐good‐as random assignment of FTP suspension, we estimate the effect of these suspensions on the probability a driver receives additional tickets. We find that financial penalties and FTP suspensions reduce the probability of reoffense for White drivers. However, among Black drivers, financial penalties have no effect and FTP suspension increases the probability of reoffense by 6‐9 percentage points. A series of additional analyses fail to produce evidence of racial differences in drivers' responses to FTP suspension, leading us to conclude that following suspension drivers make behavioral adjustments to minimize the probability of future tickets. However, these behavioral adjustments are only effective for White drivers.

逃避法律的束缚？驾驶执照暂停对犯罪概率的影响方面的种族差异

本文研究了无法付款的（FTP）驾驶执照暂停带来的意想不到的后果。与其他注重公共利益以提高执法量的交通执法文件不同，我们专注于私人回报。利用独特的管理数据集和机构功能，可以对FTP暂停进行同样好的分配，我们估计这些暂停对驾驶员获得额外票证的可能性的影响。我们发现，经济处罚和FTP暂停会降低白人司机再次举报的可能性。但是，在黑人司机中，经济处罚没有影响，而FTP暂停将重新发动进攻的可能性提高6-9个百分点。一系列其他分析未能提供证据证明驾驶员对FTP暂停的反应存在种族差异，导致我们得出以下结论：后继的悬浮驾驶者会进行行为调整，以最大程度地减少未来入场券的可能性。但是，这些行为调整仅对白人驾驶员有效。
