Auto Insurance 101: What You Need to Know Before You Buy
September 20, 2025

Auto insurance is more than just a legal requirement—it’s one of the most important investments you’ll make as a car owner. Whether you’re getting your first policy or shopping for a better rate, understanding the basics of auto insurance can save you money and help you choose the best coverage for your needs.
At JNA.org, we break down everything you need to know before you buy, from key coverage types to tips for comparing quotes.
What Is Auto Insurance?
Auto insurance is a financial agreement between you and an insurance company. In exchange for a monthly or annual payment (called a premium), the insurer agrees to help cover costs if your car is damaged, stolen, or involved in an accident.
Policies differ based on what they cover, how much they pay out, and what you’re legally required to have based on your state laws.
Why Auto Insurance Is Mandatory
In most states, having car insurance is legally required. Driving without it can lead to hefty fines, license suspension, and even criminal charges. But beyond the legal aspect, it provides critical protection for:
- You and your passengers in case of injury
- Damage to your vehicle or someone else’s
- Legal costs if you’re sued after an accident
- Replacement of your car if it’s stolen or totaled
Common Types of Auto Insurance Coverage
Before buying, it’s important to understand the basic types of coverage available. Here’s a quick overview of the most common ones:
Liability Insurance covers damage or injuries you cause to others in an accident. It’s mandatory in nearly every state.
Collision Insurance helps pay to repair or replace your vehicle after a crash, regardless of who’s at fault.
Comprehensive Insurance covers non-collision incidents like theft, fire, vandalism, or natural disasters.
Personal Injury Protection (PIP) or Medical Payments coverage pays for medical expenses, regardless of fault, and may cover lost wages.
Uninsured/Underinsured Motorist Coverage helps if you’re hit by a driver without insurance or with insufficient coverage.
What Impacts the Cost of Auto Insurance?
Many factors affect how much you’ll pay for car insurance. These include:
- Your age and driving experience
- Where you live (urban areas typically cost more)
- Your driving history and record
- The type of car you drive
- Your credit score (in most states)
- Coverage levels and deductibles
You can lower your premium by maintaining a clean driving record, choosing a higher deductible, and bundling policies (like home and auto insurance together).
How to Choose the Right Auto Insurance Policy
Selecting the right policy doesn’t have to be stressful. Start by determining how much coverage you really need. If you drive an older car, you might skip comprehensive and collision. But if you rely on your car for daily commuting or have a newer model, broader protection could save you thousands in case of an accident.
Be sure to:
- Get multiple quotes from different insurers
- Check reviews and complaint histories of providers
- Ask about discounts for good drivers, students, or bundled policies
- Read the fine print on what’s excluded from coverage
- Avoid choosing the cheapest option if it leaves you underinsured
When to Review or Update Your Policy
Life changes quickly—and so should your insurance. Review your policy at least once a year, or sooner if:
- You buy or sell a vehicle
- You move to a new location
- Your driving habits change
- You add or remove a driver from your policy
Staying proactive helps ensure you always have the right protection at the best possible rate.
