Operational Notes for Dispatch
- State routes only. Local and municipal roads are not tracked by this system. Verify local road status directly with each municipality.
- No weight limits published. The viewer does not display specific weight reduction percentages, axle load limits, or gross vehicle weight limits. Call (603) 271-2691 or email [email protected] for limits applicable to your vehicle configuration.
- No effective dates displayed. The viewer does not show a restriction start date or projected end date. Check the source URL before every run.
- No exemptions or penalties published. These details are not surfaced in the viewer UI. Contact NHDOT directly for guidance on your specific operation.
- System placeholder: One administrative record (RID 25160, District 0) shows unknown city and county. This does not represent an operational road segment.
