Heavy Vehicle Pilots
Heavy Vehicle Pilots are used to provide advanced warning to other road users that an oversize load is approaching and to facilitate the safe movement of the oversize loads by directing traffic in their vicinity. To operate in Western Australia all heavy vehicle pilots must obtain a Western Australian Heavy Vehicle Pilot Licence.
Heavy Vehicle Pilots (Pilots) provide advanced warning to other road users that an oversize vehicle is approaching and facilitate the safe movement of the oversize vehicles by directing traffic in their vicinity. Pilot Vehicles are easily recognised by a large yellow reflective sign with the words “Oversize Load Ahead” and amber flashing warning lights mounted on the roof. Pilot Vehicles escorting loads in excess of 4.5 metres in width will also display white flashing lights on the front of the vehicle. The number of Pilots accompanying an oversize vehicle will vary depending on the complexity of the load and their positioning will vary depending on where they are needed to safely manage traffic.
Important things to note:
- A pilot vehicle with flashing amber lights, signals the pilot is escorting an oversized load - approach with caution, be prepared to slow down, and maintain a safe distance.
- A pilot vehicle with alternate white flashing lights, warns road users of an impending hazard or the need for an immediate change in traffic conditions – respond promptly and adjust speed accordingly
- Directions given by Pilots are lawful directions and must be obeyed
The Heavy Vehicle Pilot Licence was introduced in 2016 to ensure that Pilots operate to an improved standard of operation and professionalism within the industry. Heavy vehicle pilots play a key role in ensuring road safety and property protection in the movement of oversize and/or overmass (OSOM) loads. All heavy vehicle pilots operating in Western Australia (WA) are required to obtain a Western Australian Heavy Vehicle Pilot Licence (HVPL).
