In case there are any changes that need to be made in the policy such as address change or any particular changes regarding the automobile or its usage, it could be done by an endorsement by the insurance provider. You need to submit a letter to your insurance provider along with the proof of the changes so that you could obtain the endorsement. There are few endorsements that might charge an extra premium from you.
It’s important to note that every company considers credit very differently, and even among insurers this factor fluctuates by state. For example, NerdWallet’s 2019 car insurance rate analysis indicates that while State Farm charges higher rates for poor credit in many states, it doesn’t seem to do so in Maine. Similar variations are true for many other companies as well.
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 
Third-party vehicle insurance is mandatory for all vehicles in Hungary. No exemption is possible by money deposit. The premium covers all damage up to HUF 500M (about €1.8M) per accident without deductible. The coverage is extended to HUF 1,250M (about €4.5M) in case of personal injuries. Vehicle insurance policies from all EU-countries and some non-EU countries are valid in Hungary based on bilateral or multilateral agreements. Visitors with vehicle insurance not covered by such agreements are required to buy a monthly, renewable policy at the border.
CTP insurance is compulsory in every state in Australia and is paid as part of vehicle registration. It covers the vehicle owner and any person who drives the vehicle against claims for liability for death or injury to people caused by the fault of the vehicle owner or driver. CTP may include any kind of physical harm, bodily injuries and may cover the cost of all reasonable medical treatment for injuries received in the accident, loss of wages, cost of care services and, in some cases, compensation for pain and suffering. Each state in Australia has a different scheme.
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.
