Pre-Start Inspection
A pre-start inspection focuses on determining whether the vehicle is mechanically safe and roadworthy before the engine is started or the vehicle is moved.
Typical checks include:
- Tyres and wheels
- Lights, indicators and reflectors
- Mirrors and cameras
- Fluid levels (oil, coolant, washer fluid)
- Leaks underneath the vehicle
- Windscreen and wipers
- Couplings, turntables and safety chains
- Safety equipment (fire extinguisher, warning triangles)
- General vehicle condition and damage
The purpose is to identify defects that could make the vehicle unsafe or non-compliant before commencing work.
Pre-Trip Inspection
A pre-trip inspection is generally broader and includes the pre-start checks, but also confirms that the vehicle, load and journey are ready to commence safely.
In addition to vehicle checks, a pre-trip inspection may include:
- Load restraint compliance
- Mass and dimension compliance
- Route assessment and permits
- Fatigue management requirements
- Documentation and work diary requirements
- Trailer and load security
- Delivery instructions and site requirements
- Any journey-specific risks
The purpose is to confirm that the entire transport task can be undertaken safely and legally.
Summary
Pre-start = Is the vehicle safe to operate?
Pre-trip = Is the vehicle, load, driver and journey safe and compliant to commence?
In practice, many fleets combine both into a single checklist and simply call it a Daily Vehicle Inspection, Pre-Operational Check, or Pre-Start Check.
That distinction can become important when discussing safety technologies, load security, route risks and Chain of Responsibility obligations.
