This expansion of cover, known as "Driving Other Cars" (where it is allowed) for the most part applies to the Policyholder as it were. Albeit absolved from the requirement to safeguard, this gives no invulnerability against claims being made against them, so an otherwise Crown Exempt authority may guarantee unexpectedly, wanting to cause the known cost of insurance premiums rather than acknowledge the open-finished introduction of adequately, self-protecting under Crown Exemption. Extensive insurance covers the majority of the above mentioned and harm to the vehicle caused by the driver themselves, and also vandalism and other dangers. This is generally the most costly kind of insurance. A few classes of vehicle possession, or use, are "Crown Exempt" from the requirement to be secured under the Act including vehicles claimed or worked by specific committees and neighborhood authorities, national park authorities, training authorities, police authorities, fire authorities, health benefit bodies, the security administrations and vehicles used to or from Shipping Salvage purposes.
