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 September 2012, it was announced that the Competition Commission had launched an investigation into the UK system for credit repairs and credit hire of an alternative vehicle leading to claims from third parties following an accident. Where their client is considered to be not at fault, Accident Management Companies will take over the running of their client's claim and arrange everything for them, usually on a 'No Win - No Fee' basis. It was shown that the insurers of the at-fault vehicle, were unable to intervene in order to have control over the costs that were applied to the claim by means of repairs, storage, vehicle hire, referral fees and personal injury. The subsequent cost of some items submitted for consideration has been a cause for concern over recent years as this has caused an increase in the premium costs, contrary to the general duty of all involved to mitigate the cost of claims. Also, the recent craze of "Cash for crash" has substantially raised the cost of policies. This is where two parties arrange a collision between their vehicles and one driver making excessive claims for damage and non-existent injuries to themselves and the passengers that they had arranged to be "in the vehicle" at the time of the collision. Another recent development has seen crashes being caused deliberately by a driver "slamming" on their brakes so that the driver behind hits them, this is usually carried out at roundabouts, when the following driver is looking to the right for oncoming traffic and does not notice that the vehicle in front has suddenly stopped for no reason. The 'staging' of a motor collision on the Public Highway for the purpose of attempting an insurance fraud is considered by the Courts to be organised crime and upon conviction is dealt with as such.
The regulations for vehicle insurance differ with each of the 50 US states and other territories, with each U.S. state having its own mandatory minimum coverage requirements (see separate main article). Each of the 50 U.S. states and the District of Columbia requires drivers to have insurance coverage for both bodily injury and property damage, but the minimum amount of coverage required by law varies by state. For example, minimum bodily injury liability coverage requirements range from $30,000 in Arizona to $100,000 in Alaska and Maine, while minimum property damage liability requirements range from $5,000 to $25,000 in most states.
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.
Any car insurance comparison tool you look at should have your state’s minimum car insurance requirements pre-loaded into its options. States requiring PIP or medpay are generally referred to as “no-fault” states, meaning that when injuries occur, each driver in a crash makes a claim with their own insurance company to pay for them. Beyond the PIP or medpay limit, the at-fault driver’s liability insurance kicks in to cover the rest.
