Safety inspection intervals for all commercial vehicles should fall between 4 – 13 weeks. The standard interval is generally 6 weeks but depending on the type of work you’re doing, the mileage covered and the terrain the vehicle is usually travelling on, this can differ. For example, if you are involved in quarry work or regularly drive on building sites, these type of conditions can contribute to accelerated ‘wear and tear’ and inspecting vehicles more frequently would be recommended. Alternatively, if your vehicle accumulates low mileage and is only ever lightly loaded, it may be more practical to inspect every 8-13 weeks.
