The defendant committed a traffic offense by weaving into oncoming traffic, even though there were no clearly marked lanes, thereby creating reasonable suspicion for a traffic stop. Even though the defendant did not violate Transp. Code §545.060(a) because there were no marked lanes, the police had reasonable suspicion to stop the defendant for violating Transp. Code §545.051, which requires a motorist to drive on the right side of the road unless passing another vehicle. Doyle v. State, 01-06-01103-CR.
