The Legal Framework Behind HGV Checks

In the UK, the driver and the operator share the legal burden of ensuring a vehicle is roadworthy before it enters the public highway. The requirement for daily checks is underpinned by several core laws:

• Road Traffic Act 1988: Driving an unroadworthy vehicle is a criminal offence, placing the driver directly in the firing line.
• Construction and Use Regulations 1986: Dictates the technical and mechanical standards your vehicle must meet.
• Goods Vehicles (Licensing of Operators) Act 1995: Requires operators to have robust systems to maintain vehicle safety.
• Operator Licence Undertaking: A formal, legally binding promise to the Traffic Commissioner to keep vehicles fit and serviceable.

We train drivers extensively on these legal requirements in our Drivers Legal Requirements CPC module, ensuring they know exactly what enforcement officers are looking for.

What Do HGV Daily Vehicle Checks Involve?

Pre-use safety inspections must be performed every 24 hours the vehicle is in operation. Even if someone else drove the vehicle earlier in the same day, if you are taking over the vehicle, it is your responsibility to check it before use.

✅ Outside the Vehicle (The Walkaround)

• Tyres & Wheels: Condition, pressure, and tread depth (minimum 1mm across a continuous band covering at least three-quarters of the breadth of tread). Check wheel nut indicators are aligned.
• Lights & Indicators: Clean, functioning, and showing the correct colour.
• Mirrors & Glass: Clean, secure, and properly adjusted to eliminate blind spots.
• Leaks: Look beneath the vehicle for fuel, engine oil, coolant, or AdBlue leaks.
• Load & Coupling: Ensure load security, curtain straps, and that trailer air lines/electrical connections are secure and undamaged.
• Exhaust: Check for excessive smoke and security of the exhaust system.

✅ Inside the Cab

• Dashboard Controls: Check for ABS/EBS warning lights, and test the horn.
• Visibility: Ensure wipers and washers operate correctly and the screen is clear of obstructions.
• Safety Equipment: Seatbelt condition, operation, and ensuring the correct Height Marker is displayed in the cab.
• Brakes: Air pressure buildup, footbrake operation, and parking brake hold.

Recording the Check: The 15-Month Rule

All HGV daily vehicle checks must be recorded—even if no defects are found (a "nil defect" report). This provides a crucial audit trail that protects both the driver and the operator.

The record must include:

• Driver’s full name and signature
• Date and vehicle registration (including trailer ID)
• Any defects found, or explicit "nil defect" confirmation
• Name of the person the defect was reported to

Operator Compliance: Operators are legally required to retain all daily check records (and the corresponding repair records) for at least 15 months. Transport Managers looking to modernise their systems often move away from paper pads. We recommend looking into Digital Vehicle Defect Reporting Tools to streamline this compliance.

Conclusion: Do You Need to Be a Mechanic?

No — but you do need to be competent and trained. Doing your daily check properly protects you, your vehicle, your operator, and everyone else on the road. It demonstrates professionalism, prevents costly roadside breakdowns, and safeguards your licence. Never assume the previous driver checked it properly. Walk the vehicle, check the vitals, and record it every single day.
