280 P.3d 1226
Wyo.2012Background
- Deputy Beeston stopped Espinoza on I-80 after observing lane deviations and a center/fog line crossing.
- Espinoza was detained for driving under the influence after failing sobriety tests and a breath test showed 0.17%.
- WYDOT suspended Espinoza's license; he challenged the stop at the contested case hearing.
- OAH upheld the stop; the district court affirmed; Espinoza appealed to the Wyoming Supreme Court.
- Court analyzes whether Deputy Beeston had probable cause to stop Espinoza for violating § 31-5-209.
- Court reviews de novo questions of law and examines the record for substantial evidence supporting the agency’s findings.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether probable cause existed to stop for lane violation § 31-5-209. | Espinoza argues no probable cause given the DVD. | Espinoza contends the stop was unsupported; statutory interpretation insufficient. | Yes; substantial evidence supports probable cause to stop. |
| Whether the DVD conformed to the deputy's report on lane violations. | DVD contradicts the report and undermines justification. | DVD confirms report; not inconsistent; supports stop. | DVD confirms, not rebuts, deputy’s report. |
| Whether the deputy’s lane violations justified stopping Espinoza under § 31-5-209. | One or two minor deviations should not trigger stop under as nearly as practicable. | Surrounding circumstances show violation; one may be reasonable under adverse conditions. | Record shows conduct sufficient to justify stop. |
| Whether the stop violated the Fourth Amendment’s reasonableness standard. | Unclear lane breach does not amount to probable cause. | Officer observed violation; reasonable belief vehicle failed to stay in lane. | Probable cause satisfied; stop reasonable. |
