426          (b) A determination under Subsection (1)(a)(ii) is reasonable if a reasonable person
427     acting under the same conditions and having regard for actual and potential hazards then
428     existing would determine that the movement could be made safely.
429          (c) On a roadway divided into two or more adjacent traffic lanes in the same direction
