The 'No Left Turn for Vehicular Traffic' sign (613) is a prohibition sign. It means you must not turn left at the junction or road ahead. This is a binding instruction for all vehicular traffic, so you must find an alternative legal route if left is your intended direction.
The instruction applies from the point where you see the sign, or from the stop line or road markings associated with it. The prohibition is in effect continuously unless a supplementary plate indicates specific times or vehicle types for which an exception applies.
Yes, exceptions may be shown on supplementary plates attached to the sign. These could specify certain times of day, particular types of vehicles (like buses or emergency services), or specific purposes for which a left turn is permitted. Always read these supplementary plates carefully.
A common trap is assuming you can turn left if other drivers are doing so, or if there appears to be no immediate traffic. The sign is a legal prohibition, and 'local habits' or another driver ignoring the sign do not grant you permission to break the law. Another trap is not noticing or correctly interpreting supplementary plates, leading to an illegal manoeuvre.
If the sign prohibits a left turn and you intended to go left, you must choose a different legal route. Look for alternative roads ahead or around the area that allow you to reach your destination. Do not attempt the left turn, as this would be a contravention of traffic regulations.
