Why Daily Walkaround Checks Matter for 7.5-Tonne Vehicles

Every driver of a 7.5-tonne (Category C1) vehicle operating commercially in the UK is legally required to carry out a daily walkaround check before driving. This requirement is set out in the Road Vehicles (Construction and Use) Regulations 1986 and enforced by DVSA roadside inspectors. Failing to carry out a proper check — or driving a vehicle with a known defect — can result in a prohibition notice, a fixed penalty, points on your licence, and in serious cases a criminal prosecution. For employers, a failure to implement a proper daily check system can result in operator licence sanctions.

Beyond the legal obligation, daily checks protect you, your load, and other road users. A 7.5-tonne vehicle with a defective tyre, faulty brakes, or a broken light is significantly more dangerous than a car with the same fault, both because of the vehicle's mass and because of the stopping distances involved. The walkaround check is the driver's last line of defence before a potentially defective vehicle enters the public road.

What the Law Requires

The DVSA's Guide to Maintaining Roadworthiness sets out the expectation that drivers check their vehicle at the start of every working day, and after any break where the vehicle has been left unattended for an extended period. The check must cover all the items listed below. Drivers must report any defects found using their employer's defect reporting system — typically a paper or electronic defect report card — and must not drive the vehicle if a defect makes it unroadworthy until the defect has been assessed and, if necessary, repaired.

The operator (your employer or, if you are self-employed, you) is responsible for maintaining a record of daily checks and defect reports. DVSA inspectors can request these records during a roadside check or an operator compliance audit. Records should be kept for at least 15 months.

The Complete 7.5-Tonne Daily Walkaround Check

The following sequence covers all the items required by DVSA guidance for a 7.5-tonne vehicle. It is organised as a logical walk around the vehicle to avoid missing items. Allow at least 15–20 minutes for a thorough check.

1. Cab and Controls (Before Starting Engine)

• Mirrors: Check all mirrors are present, clean, correctly adjusted, and not cracked or loose. Ensure you have a clear view to the rear and both sides.
• Windscreen and windows: Check for cracks, chips, or damage that obstructs your view. Ensure wipers are in good condition and washer fluid is topped up.
• Instruments and warning lights: Check all gauges (fuel, oil pressure, coolant temperature, air pressure) are reading correctly. Note any warning lights that illuminate and do not extinguish after start-up.
• Steering: Check for excessive play in the steering wheel (more than 13° of free movement is a defect on a vehicle of this size).
• Seat and seatbelt: Ensure the driver's seat is secure and adjustable, and that the seatbelt is present, undamaged, and latches correctly.
• Horn: Test the horn is working.
• Lights and indicators: Check all cab-controlled lights are working — headlights (main and dipped), sidelights, fog lights, hazard lights, and indicators. Check the dashboard warning lights for any brake or ABS faults.

2. Engine Bay Check

• Engine oil level: Check using the dipstick. Top up if below the minimum mark. Note any signs of oil contamination (milky appearance indicates coolant mixing, which is a serious fault).
• Coolant level: Check the expansion tank. Do not open the cap when the engine is hot. Top up with the correct coolant if low.
• Power steering fluid: Check the reservoir level. Low fluid can cause heavy steering and pump damage.
• Brake fluid: Check the reservoir. A low level may indicate a brake system leak — do not drive if significantly low.
• Battery: Check terminals are secure and free from corrosion. Check the battery is held down securely.
• Air filter: Check the restriction indicator if fitted. A blocked air filter reduces engine performance and increases fuel consumption.
• Belts and hoses: Check for cracks, fraying, or leaks. Do not drive if a belt or hose appears about to fail.

3. Front of Vehicle

• Headlights and indicators: Walk to the front and visually confirm both headlights, sidelights, and indicators are working (activate from the cab if necessary).
• Number plate: Check the front number plate is present, secure, clean, and legible.
• Bumper and bodywork: Check for damage that could create a hazard (sharp edges, loose panels).
• Tow coupling (if fitted): Check the coupling is in good condition and the safety pin is in place.

4. Nearside (Left Side) of Vehicle

• Tyres: Check tread depth (minimum 1 mm across the central three-quarters of the tread width for C1 vehicles, though 2 mm is recommended), tyre pressure (use a gauge — visual checks alone are unreliable for commercial tyres), and condition (cuts, bulges, exposed cords, or uneven wear are all defects). Check the valve is present and undamaged.
• Wheel fixings: Check wheel nuts are present and show no signs of looseness (rust streaks, paint cracking around the nut, or a nut that can be moved by hand are all warning signs). Use a wheel nut indicator if fitted.
• Suspension: Check for obvious damage, leaks from air suspension bags (if fitted), or broken springs.
• Fuel tank: Check the filler cap is secure and there are no signs of fuel leaks.
• Bodywork and load restraint: Check the body panels are secure, the load doors/curtains are undamaged, and load restraint equipment (straps, bars, nets) is present and in good condition.
• Marker lights and reflectors: Check all side marker lights and reflectors are present and undamaged.

5. Rear of Vehicle

• Rear lights: Check brake lights, reversing lights, rear fog light, and indicators are all working. Use a wall or a colleague to confirm brake lights.
• Number plate and lighting: Check the rear number plate is present, clean, legible, and correctly illuminated.
• Rear reflectors: Check red rear reflectors are present and undamaged.
• Rear underrun protection: Check the rear underrun bar (if fitted) is secure and undamaged.
• Load security: Check rear doors, tail lift (if fitted), or curtain are secure and the load is properly restrained. A tail lift must be stowed correctly before driving.

6. Offside (Right Side) of Vehicle

Repeat the nearside tyre, wheel, suspension, bodywork, and marker light checks on the offside. Pay particular attention to the exhaust system — check for leaks, excessive noise, or damage that could allow exhaust gases to enter the cab.

7. Underneath the Vehicle

• Fluid leaks: Check the ground under the vehicle for oil, coolant, fuel, or brake fluid. A fresh puddle or drips indicate a leak that must be investigated before driving.
• Brake lines and air lines: Where visible, check for damage, chafing, or loose connections.
• Prop shaft: Check for obvious damage or missing universal joints (if accessible).

8. Brakes (Functional Check)

• Air brake pressure: For air-braked vehicles, allow the system to build to full pressure before moving. The low-pressure warning light and buzzer should extinguish once pressure is reached. Check the pressure does not drop excessively when the brakes are applied.
• Parking brake: Apply the parking brake and attempt to drive forward gently — the vehicle should not move. Release and confirm the vehicle moves freely.
• Service brake: At low speed in a safe area, apply the brakes firmly and check the vehicle stops in a straight line without pulling to one side.

Defect Reporting: What to Do When You Find a Fault

If you find a defect during your walkaround check, you must record it on your employer's defect report form (paper or electronic) before driving. Defects are classified as either minor (can be driven with caution pending repair) or dangerous (vehicle must not be driven until repaired). Common examples:

Never drive a vehicle you know to be unroadworthy. If your employer pressures you to drive a defective vehicle, you have the right to refuse, and DVSA provides a confidential reporting line for drivers who face this situation.

Daily Check Records and Driver CPC

Daily walkaround checks and defect reporting are a core topic in Driver CPC periodic training. Understanding your legal obligations as a driver, and the operator's obligations as a licence holder, is tested in the Driver CPC Case Studies module. For a full guide to the Driver CPC qualification and what it covers, see our guide: Complete Guide to Driver CPC UK 2026.
