Wilton Larron Mahaffey, Appellant v. the State of Texas

Summary

The Texas Court of Criminal Appeals reversed the Court of Appeals, holding that a merge is not a "turn" under Texas Transportation Code § 545.104(a) and therefore does not require a turn signal; the case was remanded for the appellate court to determine whether the merge constituted a lane change that would require a signal. Justice Keller, dissenting, argued that the majority overstates the holding and would have required a signal for merges.
