What percentage of fatal truck crashes are caused by noncitizen or undocumented drivers?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Available reporting does not provide a single, authoritative percentage of fatal truck crashes caused by noncitizen or undocumented drivers; federal data cited in these sources says about 16–19% of U.S. truck drivers are foreign-born but does not translate that into a share of fatal crashes [1] [2] [3]. Recent high-profile fatal crashes involving drivers described by federal or state officials as undocumented sparked new DOT rules, audits and state funding threats but the sources note that comprehensive crash-rate comparisons by immigration or legal status are not published [4] [2] [1].
1. No clear national percentage exists — federal data gaps
There is no single percentage in the cited reporting that answers “what share of fatal truck crashes are caused by noncitizen or undocumented drivers.” Reuters and other outlets cite that roughly 16% of U.S. truck drivers were born abroad [1] [2], and Axios/other reporting give a similar ~18% figure for immigrant drivers [3]. None of the sources provide a systematic federal statistic that measures fatal-crash involvement by drivers’ citizenship or immigration status, and one industry analysis explicitly says comprehensive data comparing crash rates by nativity is not published [2] [1].
2. High-profile cases drove policy — not comprehensive epidemiology
Federal action in 2025 followed several widely reported fatal crashes involving drivers identified as in the country without authorization or as “non-domiciled” CDL holders. Those incidents — such as the August Florida crash that killed three people — prompted emergency DOT rules, visa pauses for foreign commercial drivers and audits of state CDL programs [5] [4] [1]. Reporting makes clear policymakers linked specific crashes to regulatory change, but the sources do not present those cases as establishing a national causal percentage [4] [1].
3. Proportion of foreign-born drivers ≠ proportion of crashes
Industry and government sources cited different context numbers: FMCSA/Reuters notes about 16% of truck drivers were born outside the U.S. [1], while trade/industry materials cite about 19% foreign-born among drivers [2]. One insurance-industry write-up compared the small number of identified fatal crashes involving non-domiciled CDLs to total fatal truck crashes (stating roughly five such crashes among 1,600 reported to mid‑2025, or ~0.31%), but it also acknowledged federal agencies do not systematically publish crash rates by immigration status [2]. That analysis indicates that isolated counts of high-profile incidents can give misleading impressions when compared to the whole industry [2].
4. Conflicting narratives: safety vs. immigration enforcement
Federal officials framed actions as road‑safety measures — citing English proficiency rules and vehicle/driver auditing — while critics and some states framed the moves as immigration enforcement or politically driven. The DOT and DHS tied regulatory pressure to specific crashes and to audits finding improperly issued CDLs, including California’s agreement to revoke 17,000 CDLs flagged by the department [1] [5]. Meanwhile, state officials and some coverage warned these policies risk removing large numbers of drivers from the road amid industry shortages and argued English‑test enforcement could be used as an immigration sweep [6] [3] [7].
5. What the sources do and do not show about culpability
The sources document individual prosecutions and allegations — for example, state charges in the Florida case and ICE detainers tied to several crashes — but they do not provide evidence that undocumented status alone causes disproportionate crash risk [5] [8]. Industry reporting and FMCSA materials cited in these sources explicitly state there is no comprehensive published comparison of crash rates by nativity or legal status [2] [1]. Therefore, attributing a specific percentage of fatal truck crashes to undocumented drivers is not supported by the cited material.
6. Policy implications and hidden incentives
Actions documented in these sources — emergency DOT rules, audit threats to state funding and visa pauses — respond to political pressure amplified by high‑profile crashes [4] [1]. That creates incentive for agencies and advocates to emphasize cases that link immigration status to roadway danger. Conversely, industry analyses emphasize the low share of identified cases involving non‑domiciled CDLs relative to total fatalities to argue against broad crackdowns [2]. Readers should note both safety and political enforcement agendas shape how the statistics are deployed in public debate [4] [3].
Limitations: available sources do not include a nationally standardized dataset that breaks fatal truck-crash responsibility down by drivers’ citizenship or immigration status; therefore precise percentage estimates are not available in current reporting [2] [1].
