State of Missouri v. Anthony James Smith

Summary

The Court affirmed Smith’s conviction, holding that operating a vehicle onto the shoulder, including briefly crossing the fog line, violates the statutory requirement to drive on the right half of the roadway. Because the observed violation supplied probable cause for the traffic stop, the stop was constitutionally reasonable and the marijuana and statements obtained afterward were not subject to suppression. The court’s disposition affirmed the circuit court’s denial of Smith’s suppression motion.
