Core Refusal Reason
The proposed development constitutes a material contravention of national road policies and fails to meet mandatory sight visibility standards on a high-speed national route (N84), creating a significant traffic hazard.
Decision Maker's Conclusion
- The development is a material contravention of policies MPT 23 and MTP 24, which seek to protect the capacity and safety of the national road network by restricting additional traffic from direct accesses onto routes with speed limits exceeding 60 km/h.

- In the absence of any proposed improvement works to the existing substandard access onto the N84, the development would endanger public safety by reason of traffic hazard and obstruction of road users.
