Which of the following statements about the meaning of vehicle traffic lights is INCORRECT?
As a rule, you may turn right on a circular red light after stopping if you do not obstruct other traffic, but there is a separate rule where a dedicated right-turn signal is installed (Enforcement Rule, Appendix 2). Work out which traffic light the rule and the exception each apply to.
Answer: ④
Explanation
Appended Table 2 of the Enforcement Rule allows a right turn on a circular red after stopping, as long as other traffic is not obstructed, but separately states that a right turn is not allowed when the right-turn three-color signal is red. So the statement about turning right on a red right-turn signal after stopping is wrong. Proceeding on a green arrow and turning left on green where an unprotected left-turn sign is posted are correct.
