Draft CMVR provisions for adapted vehicles and L1-1 vehicles

Applicability

Targets adapted M1 and N1 vehicles, adapted L-category vehicles, tricycles and L1-1 vehicles, with different clauses applying by category and modification type.

Key requirements

• Use the proposed Adapted Vehicle terminology and disability coding in relevant forms and licences.
• Meet AIS-169 braking and steering-effort provisions for affected M1 and N1 vehicles.
• Apply AIS-178 provisions to specified adapted L-category vehicles.
• Apply AIS-183 type-approval requirements to L1-1 category vehicles.
• Preserve recognition of existing approvals as stated in the draft transition text.

OEM impact

• Review base-vehicle and adaptation responsibility across OEM, converter and registration workflows.
• Update type-approval documents, forms, dimensions and control-system specifications by vehicle category.
• Create a transition plan for prior approvals and new production.

Supplier impact

• Adaptation-kit and control suppliers need evidence for braking, steering and ergonomic requirements.
• Converters need controlled installation instructions, inspection criteria and traceability.
• Component changes must be coordinated with the base-vehicle approval holder.

Testing / homologation impact

• Testing may include braking, steering effort, dimensional compliance and adaptation inspection.
• The approval route depends on vehicle category and whether the change is OEM-built or post-registration adaptation.
• Testing agencies may need category-specific information and modification drawings.

Action points

• Classify current adapted-vehicle offerings by category and modification route.
• Compare design and documentation against AIS-169, AIS-178 and AIS-183.
• Protect existing-approval records and identify transition assumptions.
• Monitor MoRTH for the final notification before applying mandatory dates.

Open questions

• Has a final notification superseded any proposed implementation date?
• How will state-level adaptation approvals align with the central type-approval process?
• What evidence will testing agencies accept for legacy modifications?
