ANNOTATION

Annotator's note. Since § 42-4-1003 is similar to § 42-4-903 as it existed prior to the 1994 amending of title 42 as enacted by SB 94-1, relevant cases construing that provision have been included with the annotations to this section.

Forward automobile not required to turn further to right. Under this section it would seem clear that where the left half of the roadway is clear and the forward automobile is on the right half thereof, the driver of the latter is not required to turn further to the right upon hearing a passing signal given by the driver of an overtaking car. Vasquez v. Morrow, 106 Colo. 540, 107 P.2d 246 (1940).

Failure to turn does not justify overtaking vehicle to drive into collision. The mere failure of the driver of an overtaken vehicle to turn to the right does not justify the operator of the overtaking vehicle to drive on into a collision with the first. Vasquez v. Morrow, 106 Colo. 540, 107 P.2d 246 (1940).

Situation in which section not applicable. Where plaintiff attempted to pass defendants' truck within 200 feet of an intersection on a four-lane, divided highway and defendants' driver attempted to make a U-turn in front of plaintiff without giving a warning signal, although plaintiff gave all signals customarily used in indicating that he was about to pass, this section did not apply and defendants' negligence was the proximate cause of a collision between the vehicles of the parties. Wilson v. Stroh, 121 Colo. 411, 216 P.2d 999 (1950).
