Sobriety Tests After Accidents: Your Rights and Obligations

In most U.S. states, implied consent laws mandate chemical testing (breath/blood/urine) after a DUI arrest involving serious injury or death.

Refusal consequences: Automatic license suspension (1+ years), admissible as evidence of consciousness of guilt, enhanced criminal penalties, mandatory ignition interlock.
Warrantless blood draws: Birchfield v. North Dakota (2016) — breath test OK without warrant; blood test generally requires warrant unless exigent circumstances.
Field sobriety tests (FSTs): Usually voluntary (no penalty for refusal), but refusal may be used against you.
State variation: Laws differ — know your jurisdiction.

Remain polite, comply with documentation (license, registration).
Decline FSTs politely if you choose (but know consequences).
Chemical test refusal carries severe administrative + criminal penalties in injury/death cases.
Contact a DUI attorney immediately.
