Conn. Gen. Stat. § 14-246a: Right-of-way at junction of highways.

The driver of any vehicle on a highway which joins but does not cross another highway shall, unless otherwise directed by a traffic officer, grant the right-of-way at the point where such highways join to any vehicle approaching on the other highway from either direction when such vehicles are arriving at approximately the same time at the area which would be common to both highways if they crossed each other. Failure to grant the right-of-way as provided by this section shall be an infraction.
