Why These Myths Stick — and What They Cost You
Car insurance is one of the larger fixed costs in a family budget, yet most households renew their policy with surprisingly little scrutiny. Persistent myths — passed along by word of mouth or simply never challenged — lead families to make decisions that inflate their premiums, leave gaps in their cover, or both.
The myths covered here are widespread and specific: they involve the details of how premiums are actually calculated, how no-claims bonuses work, and which add-ons genuinely earn their keep. Getting these details right doesn't require becoming an insurance expert — it just requires knowing which assumptions to question. You might also find it useful to check our car maintenance myths that cost drivers money, since misplaced beliefs about upkeep can affect both reliability and insurance outcomes.
Myth
Red cars cost more to insure because insurers charge extra for bright colors.
Fact
Vehicle color has no bearing on car insurance premiums. Insurers rate risk based on the vehicle's make, model, engine size, and your driving history — not its paint.
This myth is remarkably persistent, but color simply doesn't appear on any standard insurance rating formula used by US insurers. What actually drives your premium includes the car's safety record, repair costs, theft rates for that model, and your personal driving history. A red sports car costs more to insure than a red minivan — but only because of the vehicle type, not the color. When shopping, focus your energy on those real factors rather than the shade of your vehicle.
Myth
Third-party-only insurance is always cheaper than comprehensive coverage.
Fact
Comprehensive policies are sometimes priced lower than third-party-only cover, depending on the insurer's risk calculations and your vehicle's profile.
Counterintuitive as it sounds, insurers have historically found that drivers who seek minimal, third-party-only cover can be statistically higher-risk, which pushes those premiums up. Meanwhile, comprehensive policyholders tend to be assessed as lower-risk on average. The gap varies by insurer and individual circumstance, so always compare both levels of cover when getting quotes. Assuming third-party is automatically the budget option without checking can leave money on the table — or leave your own vehicle unprotected unnecessarily.
Myth
You automatically lose your entire no-claims bonus if you make any claim.
Fact
Most insurers reduce your no-claims bonus by a set number of years per claim rather than wiping it entirely, and some allow you to protect it for a fee.
The mechanics of no-claims discounts (NCDs) vary by insurer, but a single claim rarely zeroes your bonus outright. Many policies reduce it by two or three years — still a financial hit, but not a complete reset. No-claims protection add-ons let you make a limited number of claims without affecting your discount, though you should weigh the cost of that add-on against the potential saving. Read your policy terms carefully so you understand exactly how claims are handled before one occurs, not after.
Myth
Adding your teenager as a named driver will always send your premium through the roof.
Fact
Adding a young driver raises premiums in most cases, but the increase varies widely — and adding an experienced driver can sometimes bring premiums down.
Young, inexperienced drivers are statistically higher-risk, so adding them to a policy typically increases cost. However, the size of that increase depends on the insurer, the vehicle, and the young driver's own record. Conversely, adding a more experienced, low-risk adult driver to a policy can reduce the overall premium in some cases. One important caution: never list an experienced driver as the primary driver when a younger person is the main user — this is called fronting and constitutes insurance fraud, which can void a claim entirely.
Myth
Your credit score has nothing to do with your car insurance costs.
Fact
In most US states, insurers are permitted to use a credit-based insurance score as one factor when calculating premiums.
Most major US insurers use a credit-based insurance score — a distinct calculation from your standard credit score, but derived from similar underlying credit data — as part of their rating process. Research by the Federal Trade Commission has found that these scores correlate with the likelihood of filing claims. A handful of states, including California, Hawaii, and Massachusetts, restrict or prohibit this practice. If you live in a state where it applies, improving your broader financial health over time may gradually influence your insurance costs, though insurers weight many factors together.
Myth
Optional add-ons like roadside assistance and courtesy car cover are always worth having.
Fact
Many families already have roadside assistance through other memberships or manufacturer warranties, making duplicate coverage an unnecessary cost.
Before accepting every add-on offered at renewal, check what you already have. Roadside assistance may be included in a manufacturer's warranty, a separate auto club membership, or even a credit card benefit. Paying for it through your insurer as well means you're covering the same risk twice. Review each add-on individually against what you already own. That said, some add-ons — like legal expenses cover — can provide genuine value for families, so the goal is an informed choice rather than a blanket rejection of all extras. See our guide to cutting insurance costs without cutting cover for a fuller breakdown of how to assess each option.
Putting Accurate Information to Work
Correcting a myth is only useful if the accurate picture helps you act differently. Here's the practical upshot:
- When getting quotes: Compare comprehensive and third-party cover side by side — never assume one is cheaper.
- At renewal: Check whether no-claims protection is worth its cost by calculating how much your discount is currently worth versus the add-on's price.
- Before adding drivers: Understand that the impact depends on the individual's profile, and never misrepresent who the primary driver is.
- Before accepting add-ons: Audit what roadside assistance or other benefits you already hold through other policies or memberships.
- On credit: If you live in a state where credit-based insurance scoring applies, general financial health can be a slow-moving lever on costs.
Families who question inherited assumptions tend to find real savings — not by reducing protection, but by paying accurately for the protection they actually need.
