The first step to buying car insurance is to gather personal and vehicle information to get an accurate quote. Familiarize yourself with basic coverage options, such as liability, collision and comprehensive coverage, to determine your needs. You can then get quotes from an agent, broker or the insurer directly. After comparing multiple quotes based on cost and coverage, select a provider. Assuming they have all the necessary information, many insurance companies can provide coverage the same day you get a quote.
For drivers switching insurers, remember to align policy start dates to avoid coverage lapses. Even if you already have a policy, shopping around may help you find better coverage for your needs at a lower rate.
