Boulder insurance requirements

Drivers in Boulder must meet or exceed Colorado’s minimum car insurance requirements, which are abbreviated as 25/50/15. The minimum coverage limits include:

  • $25,000 in bodily injury coverage per person
  • $50,000 in bodily injury coverage per accident
  • $15,000 in property damage coverage per accident

Drivers who want a cheap rate may choose to purchase a minimum coverage policy to keep costs low. However, most insurance experts recommend higher liability limits if you can afford them. If you cause an accident and the damages and injuries exceed your policy’s limit, you would be responsible for paying the rest out of pocket. Higher liability limits offer more financial protection.

Additionally, if you lease or finance your vehicle, most lenders require drivers to carry full coverage insurance until the loan is repaid. Full coverage policies include comprehensive and collision coverages.

Car insurance discounts in Boulder

Most car insurance companies in Colorado offer at least a few discounts to help drivers lower their premiums. The exact savings differ between providers, but some of the most common ones include:

  • Multi-policy discount: If you purchase an auto and home, condo or renters insurance policy from the same company, you may qualify for a discount.
  • Good student discount: Drivers under 25 who maintain a certain GPA in school can often qualify for a lower car insurance rate.
  • Safe vehicle discount: If your car is equipped with safety features like anti-lock brakes, airbags or an anti-theft device, you might be able to get a cheaper rate.
  • New vehicle discount: Insuring a new vehicle can sometimes help you qualify for a discount on your premium.

While car insurance discounts can help you save money, every discount has a different savings potential. When comparing insurers, look at the average savings for each discount you can qualify for in order to get the lowest rate possible.

Frequently asked questions

What is the best car insurance company?

The best car insurance company is different for every driver, because every driver has different insurance needs. The best provider for you is the one that meets your needs, including what coverages you need and how much you can afford to pay for insurance.

How much car insurance do I need in Boulder?

Drivers in Boulder are required to purchase at least 25/50/15 personal liability car insurance. However, most insurance professionals recommend that most drivers raise their coverage limits or purchase a full coverage policy for additional protection. Working with a licensed agent might help you determine how much car insurance you need, including which coverages and what levels to purchase.

Do I need to buy full coverage in Boulder?

Full coverage is not required by law, but if you have a loan or lease on your vehicle you probably need a full coverage policy. Full coverage may also be a good idea if you have a new or expensive vehicle, or if you do not have the finances to pay for vehicle repairs out of pocket.
