Cheapest car insurance in South Dakota

Nationwide has the cheapest average rate in the state at $1,526 a year.

While Nationwide is the cheapest for many drivers, the perfect insurer for you may be a different company.

Insurers consider a wide variety of factors when setting a premium including your driving record, credit score, age, marital status as well the vehicle. Where you live also affects rates.

“States that have a higher rate of severe weather that damages cars or helps cause accidents will typically have higher rates,” says Chong Gao, director of product management R&D at Mercury Insurance. “Florida, for example, is prone to extreme weather like hurricanes and its car insurance costs are consequently much higher.”

Insurance companies crunch all this data with proprietary algorithms, which can result in dramatic differences in premium quotes.

The data clearly shows the range of premiums for similar drivers.

In South Dakota, as mentioned earlier, the cheapest policy is with Nationwide with an average rate of $1,526 a year. Allstate follows with an average premium of $2,070 a year or $173 a month and State Farm with premiums of” $2,096 a year or $175 a month.

Progressive is the most expensive insurer with an average premium of $3,163.

Shopping for car insurance in South Dakota

Shopping around for coverage is a great way to make sure you are getting the best rates on your auto insurance. Experts often tell consumers to shop for insurance yearly. But that doesn’t necessarily mean you should be looking to switch.

“I recommend that people stay with the same insurance company, as they tend to get a better rate when they have been with the same carrier for more than 12 months.” The more tenure you have with a carrier,” the more potential there is to earn benefits,” says Tim Bottini, a Country Financial insurance agent based in St. Louis. “The carrier can also review your claims history and provide information about applicable discounts.”

But make sure you are comparing like coverage levels and deductibles.

“It is extremely important to make sure you start off with an apples-to-apples comparison,” Bottini says. “However, if a person has low limits, say 25/50/25 – limit per person/per occurrence/limit for property damage – I am going to recommend and quote at least 50/100/100. Depending on their age/income and profession, I would quote higher limits to protect their net worth and earnings potential.”

Bottini also says people can save money on their car insurance by keeping their credit score up, following the speed limit and placing both home and auto insurance with the same carrier.

Cheapest car insurance in South Dakota by age

Insurance companies consider your age when setting a premium and teens and young adults pay more for coverage as statistics show that young drivers, because they are inexperienced, have more accidents and claims.”

Regardless of your age, in South Dakota, Nationwide is the most affordable coverage with an average rate of $1,526 a year.

As teens transition into young adults and get more experience under their belt rates start to drop. By their mid to late-20s (assuming they keep their record clean) driver rates should stabilize and then stay stable until the driver moves into their 70s when rates will start climbing again.

Cheapest car insurance for senior drivers in South Dakota

Seniors in the state pay more for coverage than all other driver groups, except for teens. Nationwide is the most affordable option for seniors with a yearly premium of $1,243 or $104 a month. State Farm was the second cheapest at $1,818 and Farmers rounded out the top three at $1,841.

Seniors tend to pay more for coverage due to age. Many seniors suffer from vision and hearing issues as well as slowing reflexes. In addition, medications they may take can impact their driving. All of these factors combined lead to more accidents and claims which will result in a higher premium.

The chart below shows the average premium for senior drivers.

Car insurance for young drivers in South Dakota

While young adults pay less than teen drivers, they still pay more than older more experienced drivers. The best choice for young adults (early 20s) in South Dakota is Nationwide with an annual rate of $2,392 or $199 a month.

Farmers had the second cheapest premium at $2,905 a year followed by State Farm was third at $3,142.

Car insurance for teen drivers in South Dakota

Adding a teen to a car insurance policy will always push up the rate. Teens are the least experienced drivers out on the road which leads to more accidents and claims and higher premiums.

“Teen drivers are statistically more likely to be involved in accidents due to their lack of driving experience and tendency to engage in risky behaviors like speeding,” says Eliezer Zupnick, founder of East Leads Group LLC. “Teens are involved in three times as many auto accidents per mile compared to drivers aged 20 and up, making them a high-risk category for insurers.”

For South Dakota teens, Nationwide is the most affordable option with a premium of $4,562 a year or $380 a month. State Farm is the next most affordable at $4,973 a year or $414 a month followed by Auto-Owners running $5,952 a year.

If your teen has a B average or better, ask for a good student discount to help save a bit of money. Having your teen drive an older vehicle will also help save some money. If the car is old enough that you wouldn’t repair it after an accident, you may be able to drop collision and comprehensive.

In South Dakota, the average premium is $2,280, which makes South Dakota the 5^th most expensive state for coverage.

All states have large metropolitan areas, which will always push up the cost of insurance as more vehicles on the road lead to more accidents and claims. A high crime rate will also impact rates.

“If a state has a higher rate of car insurance claims associated with vandalism or car theft, prices are usually higher because car insurance companies view insuring these cars as a higher risk for them,” says Chong Gao, director of product management R&D at Mercury Insurance.

Minimum car insurance requirements in South Dakota

Most states require all drivers to carry a minimum amount of liability coverage to drive legally. South Dakota requires drivers to carry 25/50/25 in liability coverage, which translates into:

$25k for bodily injury and $50,000 for death for a person involved in an accident

$50k for bodily injury and $100,000 for death for two or more people in an accident

$25k for property damage for a single accident

These required minimums are fairly average when compared to other states. However, these minimums are rarely enough coverage if you are involved in a serious accident. Once your coverage levels are exceeded, you will be on the hook for any remaining damage.

Experts typically recommend carrying 100/300/50 as a minimum liability coverage level.

What our expert says

Q: Is it a good idea to switch insurers?

Tim BottiniInsurance agent, Country Financial

“I recommend that people stay with the same insurance company, as they tend to get a better rate when they have been with the same carrier for more than 12 months. The more tenure you have with a carrier, the more potential there is to earn benefits. The carrier can also review your claims history and provide information about applicable discounts.”
