Evidence

As of the current eCFR version, CDL knowledge tests may still be administered in a foreign language if no interpreter is used; CDL skills tests must be conducted in English.

Unverified model/legacy excerpt; not proof. AI summary (separate from source): Current federal CDL testing rules partially match the commitment: skills testing is English-only, but the knowledge test is not federally English-only. I found no official change in the 2026-09-08 to 2026-09-10 lookback window showing that this had changed.

Tiffany's official newsletter described Dalilah Law as legislation he cosponsored and said it would stop states from issuing CDLs to illegal aliens and mandate English-only CDL testing.

Unverified model/legacy excerpt; not proof. AI summary (separate from source): This is concrete legislative effort by Tiffany toward the commitment, but it reflects a pending legislative vehicle rather than enacted federal policy.

The promised federal outcome has not been delivered. Current federal CDL rules require skills tests to be conducted in English, but still allow CDL knowledge tests in a foreign language without an interpreter, so there is no full English-only CDL testing mandate. Tiffany cosponsored legislation in the same congressional term to create such a mandate, which is a serious legislative attempt, but the evidence does not show enactment or implemented federal policy.
