In most U.S. states, moving violations, including running red lights and speeding, assess points on a driver's driving record. Since more points indicate an increased risk of future violations, insurance companies periodically review drivers' records, and may raise premiums accordingly. Rating practices, such as debit for a poor driving history, are not dictated by law. Many insurers allow one moving violation every three to five years before increasing premiums. Accidents affect insurance premiums similarly. Depending on the severity of the accident and the number of points assessed, rates can increase by as much as twenty to thirty percent. Any motoring convictions should be disclosed to insurers, as the driver is assessed by risk from prior experiences while driving on the road.
In 1930, the UK Government introduced a law that required every person who used a vehicle on the road to have at least third-party personal injury insurance. Today, this law is defined by the Road Traffic Act 1988, (generally referred to as the RTA 1988 as amended) which was last modified in 1991. The Act requires that motorists either be insured, or have made a specified deposit (£500,000 in 1991) and keeps the sum deposited with the Accountant General of the Supreme Court, against liability for injuries to others (including passengers) and for damage to other persons' property, resulting from use of a vehicle on a public road or in other public places.
To reduce the insurance premium, the insured party may offer to pay a higher excess (deductible) than the compulsory excess demanded by the insurance company. The voluntary excess is the extra amount, over and above the compulsory excess, that is agreed to be paid in the event of a claim on the policy. As a bigger excess reduces the financial risk carried by the insurer, the insurer is able to offer a significantly lower premium.
Yes, you surely can avail the NCB if you change your insurance provider at the time of renewing the policy. All you would need to do is producing a proof of the earned NCB from your current insurance provider. You can produce the original copy of your expiring policy and a certification that you haven’t filed any claim for the (expiring) insurance plan. A renewal notice or a letter stating that you’re entitled to the NCB from your previous insurance provider can be a proof for this.
Several Canadian provinces (British Columbia, Saskatchewan, Manitoba and Quebec) provide a public auto insurance system while in the rest of the country insurance is provided privately [third party insurance is privatized in Quebec and is mandatory. The province covers everything but the vehicle(s)]. Basic auto insurance is mandatory throughout Canada with each province's government determining which benefits are included as minimum required auto insurance coverage and which benefits are options available for those seeking additional coverage. Accident benefits coverage is mandatory everywhere except for Newfoundland and Labrador. All provinces in Canada have some form of no-fault insurance available to accident victims. The difference from province to province is the extent to which tort or no-fault is emphasized. International drivers entering Canada are permitted to drive any vehicle their licence allows for the 3-month period for which they are allowed to use their international licence. International laws provide visitors to the country with an International Insurance Bond (IIB) until this 3-month period is over in which the international driver must provide themselves with Canadian Insurance. The IIB is reinstated every time the international driver enters the country. Damage to the driver's own vehicle is optional – one notable exception to this is in Saskatchewan, where SGI provides collision coverage (less than a $1000 deductible, such as a collision damage waiver) as part of its basic insurance policy. In Saskatchewan, residents have the option to have their auto insurance through a tort system but less than 0.5% of the population have taken this option.
A lot goes into an auto insurance rate quote, including your ZIP code, coverage levels, marital status, annual mileage, driving history and vehicle make, year and model. In most states, your gender and credit history are also used to determine rates. And again, the reason auto insurance comparison shopping is so important is because rates between companies are different for each person, too.
In 1998, the Progressive Insurance company started a pilot program in Texas, in which drivers received a discount for installing a GPS-based device that tracked their driving behavior and reported the results via cellular phone to the company. The program was discontinued in 2000. In following years many policies (including Progressive) have been trialed and successfully introduced worldwide into what are referred to as Telematic Insurance. Such 'telematic' policies typically are based on black-box insurance technology, such devices derive from a stolen vehicle and fleet tracking but are used for insurance purposes. Since 2010 GPS-based and Telematic Insurance systems have become more mainstream in the auto insurance market not just aimed at specialised auto-fleet markets or high value vehicles (with an emphasis on stolen vehicle recovery). Modern GPS-based systems are branded as 'PAYD' Pay As You Drive insurance policies, 'PHYD' Pay How You Drive or since 2012 Smartphone auto insurance policies which utilise smartphones as a GPS sensor, e.g. . A detailed survey of the smartphone as measurement probe for insurance telematics is provided in 
If a vehicle is to be "laid up" for whatever reason, a Statutory Off Road Notification (SORN) must be submitted to the DVLA to declare that the vehicle is off the public roads and will not return to them unless the SORN is cancelled by the vehicle's owner. Once a vehicle has been declared 'SORN' then the legal requirement to insure it ceases, although many vehicle owners may desire to maintain cover for loss of or damage to the vehicle while it is off the road. A vehicle that is then to be put back on the road must be subject to a new application for VED and be insured. Part of the VED application requires an electronic check of the MID, in this way the lawful presence of a vehicle on the road for both VED and insurance purposes is reinforced. It follows that the only circumstances in which a vehicle can have no insurance is if it has a valid SORN; was exempted from SORN (as untaxed on or before 31 October 1998 and has had no tax or SORN activity since); is recorded as 'stolen and not recovered' by the Police; is between registered keepers; or is scrapped.
