The Patient Protection and Affordable Care Act of 2010, more commonly known as Obamacare, impacted healthcare in the United States in numerous ways. The act's effects vary by person, but you'll need to have health insurance for at least nine months out of every 12 or be subject to a tax. There are exceptions to this rule based on financial hardship, your income and living situation. But in general, whether it's through Obamacare or not, you should have health insurance.
While all car insurance companies offer a similar product, they differ in how they deliver it. Some car insurance companies are basically self-service, allowing you to shop for and choose a policy completely online. Others use local agents who can meet with you and talk you through the process of buying a policy and personally handle any claims you have. Some companies use a mix of the two. Make sure you find a company that has the type of service you want.
