Common grounds to appeal a code 50L PCN
- The 'no turn' sign was missing, obscured or not visible in time.
- An exemption on the sign applied (for example 'except buses' or times of operation).
- You were directed by police or avoiding an emergency.
Also check the PCN itself: are the date, time, location, vehicle and code correct, and was it served on time? Errors can support the statutory grounds, such as procedural impropriety or 'the contravention did not occur'.
