Yes your insurance rates are impacted and affected by your credit score.
The lower your credit score the higher your insurance premiums usually are and you can usually get a lower insurance premium by having a higher credit score.
Your driving record is also taken into account when deciding the rate of your insurance premiums so if you have a good driving record your auto insurance will cost less and if you have a bad driving record then your auto insurance will cost much more.
Having a good driving record and a good credit score is key to having lower auto insurance costs.
