Inspection

All systems, sub-systems and components particularly safety critical items, of new buses including e-buses must undergo inspection and type approval/ certification as per CMVR and other applicable standards. All the statutory approvals, test certifications and compliance document be checked and compliance confirmed, before the procurement and deployment of new e-buses by the inspection and the safety officer. During operations, effective implementation calls for targeted inspection and necessary corrective actions by relevant stakeholder, as outlined in the following table for enforcement and compliance.

QnA

Q1. Before deploying a newly procured e-bus fleet, the safety officer is verifying compliance with statutory inspection requirements.

Which action is MANDATORY prior to procurement and deployment of new e-buses?

Conduct only in-house functional checks of electrical systems Obtain type approval, test certifications, and compliance documents as per CMVR and applicable standards Perform road trials without certification to assess performance Rely solely on OEM self-declaration for compliance

Q2. During a periodic inspection, an e-bus is assessed for mechanical and structural soundness to ensure continued roadworthiness.

Which set of checks BEST aligns with regular inspection of mechanical and structural integrity?

Battery SoC trends and charging history Steering free play, chassis fasteners, tyre wear, and under-chassis leakages Firmware version updates and firewall configuration Passenger information display content

Q3. A periodic audit is conducted to verify the readiness and reliability of onboard technological systems in an e-bus fleet.

Which inspection activity is MOST critical under regular ITS and technology system checks?

Testing ADAS and DFMS for calibration, accuracy, and responsiveness Replacing hardware components based on age alone Disabling alerts to reduce driver distraction Limiting real-time data transmission to conserve bandwidth

Q4. During a periodic inspection, the safety officer is evaluating passenger-related safety provisions inside an e-bus before issuing roadworthiness clearance.

Which inspection item is MOST critical to ensure passenger safety during normal operations and emergencies?

Verifying secure fastening of seats, handholds, grab rails, and availability of emergency exits Ensuring availability of infotainment and passenger information displays Checking interior colour schemes and lighting aesthetics Confirming seat fabric material matches OEM branding

S.No.

Activities

Responsibility

Regular Vehicle Inspection and Maintenance

Regular inspection of the mechanical and structural Integrity of buses

Regular inspection for the Interior safety and other features

Regular Inspection of technological systems /ITS and related sub systems

Regular inspection of e-buses are essential to ensure roadworthiness, operational safety, and system reliability. The following safety-critical systems and components shall be mandatorily checked during periodic inspections.

Regular Vehicle Inspection and Maintenance: All e-buses should undergo comprehensive inspection periodically and roadworthiness certification by the designated transport authority at scheduled intervals. In absence of in-house capabilities, such periodical inspections may be contracted from qualified third-party /external agency. These safety checks shall include the following critical components:
- Electrical System – High Voltage Connections, terminals etc.
- Charging port for functionality
- Emergency shutdown systems for operational performance
- Battery System – With specific focus on Battery Management System, battery cooling system and leakages, overheating, dashboard display of various system parameters, etc.
- Overheating of traction and other motors, coolant levels in radiator.
- Lighting system – headlights, indicator lights, brake lights, entry exit lights for operational safety after sunset.
- Steering System – for smooth operational performance, angle and height adjustments
- Tyre for inflation, tread-ware indicators, cut, abnormal tread wear, etc
- Entry – exit doors for operational functionality, retraction when faced by resistance, prevention of vehicle movement with doors open.
- Braking System – Air pressure and braking system leakages, braking performance, brake liners and brake drum/ discs for wear, brake system, Anti-lock Braking System (ABS) and parking brakes performance.
- Conduct regular firewall inspection and real time cyber security audits.

Regular inspection of the mechanical and structural Integrity of buses:

- Inspect bus body condition for cracks, loose fastening, dents and any other visible physical damage.
- Check chassis and bus body fasteners for tightness, alignment and structural integrity.
- Inspect steering system and steering mechanism for wear, free play and proper functioning.
- Verify wheel alignment, king pin inclination and hub lubrication conditions.
- Inspect tyres for cuts, abnormal treadwear pattern and tread wear indicators.
- Check driver dashboard tell-tale signs, warning indicators and signalling systems for proper operation.
- Verify functionality of passenger information systems and onboard security cameras.
- Inspect reversing buzzer and camera for effective operations
- Check under-chassis components for damage, loose fittings or leakage.
- Inspect all lights & signalling device for proper illumination and visibility
- Check mirrors and windows for cracks, visibility, secure mounting and cleanliness.

Regular inspection for interior safety and other features:

Inspect seats-cushions, secure fastening and passenger comfort

Check handholds, grab rails and seat belts (where provided)

Verify door opening and closing mechanisms for smooth and reliable operations. Also check the operations and functionality of emergency doors/ hatches/ glass breaking devices.

Ensure bus movement is permitted only when doors are fully closed.

Inspect wheelchair accessibility ramps or lifts (where provided) for functionality, secure anchorage and safety alerts.

Check operations of audible and visual alert related to safety systems.

Inspect interior cooling and ventilation systems, including air-conditioning (where provided), for proper performance.

Regular Inspection of technological systems /ITS and related sub-systems:

- Verify the operational condition and effective utilisation of all onboard technological and Intelligent Transport Systems (ITS).
- Test Advanced Driver Assistance Systems (ADAS) for proper calibration and performance.
- Verify Driver Fatigue Monitoring Systems (DFMS) for alert accuracy and responsiveness.
- Check the Battery Management System (BMS) for data accuracy, alerts, and fault reporting.
- Verify real-time vehicle monitoring systems for continuous data transmission and system health.
- Inspect onboard microprocessors and control units for fault codes, software integrity and reliable operations.
