United States v. Vargas
3:14-cr-00587
N.D. Cal.Apr 23, 2015Background
- Defendant Nubia Vargas charged with DUI and BAC ≥ .08 after officer stopped her for allegedly not coming to a complete stop at a stop sign in the Presidio on March 1, 2014.
- Vargas moved for discovery under Fed. R. Crim. P. 16 seeking records of other stops and collisions within 250 feet of the stop sign during the year before her arrest.
- Vargas contended the stop sign was located nearly 20 feet from the edge of the traveled way and that placement violated the MUTCD (Manual on Uniform Traffic Control Devices).
- Vargas’s expert asserted MUTCD required signs to be 6–12 feet from the roadway; government argued MUTCD sets a minimum lateral offset (not a maximum) and requires signs be outside the clear zone.
- The court assumed, for argument’s sake, that the sign might violate the MUTCD but concluded that any technical MUTCD violation did not render the DUI arrest suppressible nor make the requested discovery material under Rule 16.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Rule 16 requires discovery of other stops/accidents near the stop sign | Discovery material because sign placement violated MUTCD, so evidence could show stop was unlawful | MUTCD violation shows sign not placed as required; discovery needed for expert and to challenge stop | Denied — discovery not required; MUTCD issue (even if assumed) does not make DUI arrest suppressible or discovery material |
| Proper reading of MUTCD lateral distance (minimum vs maximum) | MUTCD sets only a minimum offset; government: no maximum; sign complies | Vargas: expert says 6–12 ft implies placement within that band | Court reads MUTCD as prescribing a minimum offset, not a maximum; sign complies with MUTCD language |
| Whether a MUTCD violation invalidates an ensuing DUI arrest | N/A | Vargas cites authority that signal violations can invalidate citations and argues similar rule should apply | Court: even if citation for rolling stop would be invalid, that does not make an objectively reasonable DUI arrest suppressible as fruit of an unlawful stop |
| Relevance of MUTCD compliance to suppression of evidence | N/A | Vargas: MUTCD noncompliance undermines legality of stop and justifies discovery | Court: technical/non-obvious MUTCD noncompliance does not defeat officer’s objectively reasonable observation of failure to stop; discovery denied |
