Some classes of vehicle ownership, or use, are "Crown Exempt" from the requirement to be covered under the Act including vehicles owned or operated by certain councils and local authorities, national park authorities, education authorities, police authorities, fire authorities, health service bodies, the security services and vehicles used to or from Shipping Salvage purposes. Although exempt from the requirement to insure, this provides no immunity against claims being made against them, so an otherwise Crown Exempt authority may choose to insure conventionally, preferring to incur the known expense of insurance premiums rather than accept the open-ended exposure of effectively, self-insuring under Crown Exemption.
It is an offence to use a motor vehicle, or allow others to use it without insurance that satisfies the requirements of the Act. This requirement applies while any part of a vehicle (even if a greater part of it is on private land) is on the public highway. No such legislation applies on private land. However, private land to which the public have a reasonable right of access (for example, a supermarket car park during opening hours) is considered to be included within the requirements of the Act.
Road Traffic Act Only Insurance differs from Third Party Only Insurance (detailed below) and is not often sold, unless to underpin, for example, a corporate body wishing to self-insure above the requirements of the Act. It provides the very minimum cover to satisfy the requirements of the Act. Road Traffic Act Only Insurance has a limit of £1,000,000 for damage to third party property, while third party only insurance typically has a greater limit for third party property damage.
Driving without the necessary insurance for that vehicle is an offence that can be prosecuted by the police and fines range from 841 to 3,287 euros. Police forces also have the power to seize a vehicle that does not have the necessary insurance in place, until the owner of the vehicle pays a fine and signs a new insurance policy. The same provision is applied when the vehicle is standing on a public road.
But liability coverage levels come in threes — you’ll probably see something like 50/100/50 up to 250/500/250 in typical policies. You can think of these limits like: individual injuries / total injuries / property damage. Insurers are a little more technical, calling them bodily injury liability, total bodily injury liability and physical damage liability.
