I noticed mine did and I am thinking this is down to offering a driving service. I do have coverage for it but it didn't go up right away. It went into effect 3 months after the fact and I am not sure why. I am currently paying $82 MORE a month and I am not sure if this is just me or what.
Mine did go up but it went back down. I did change vehicles and a few laws were changed in my area. I would see if maybe things changed in your area in terms of coverage and speak to your insurance provider.
I think some companies will raise it when they know you are driving more. The more you drive, the more likely are your chances of being in some form of accident, even a bumper to bumper tap on a main road which is the most common for people.
Does driving for LYFT raise your insurance?
However, adding this endorsement increases your premium 15% to 20%. USAA and Farmers both offer coverage during Period 1, which is considered the riskiest period for drivers because Lyft's lower-limit liability coverage is in effect during this time.
