I had this happen to me... Even though they aren't suppose to use it against you some places play a round about game and try to...
It will stay on your record for 5 years... Last year I went to get Motorcycle insurance (September 2013) and my broker told me to wait until November 2013 (when it drops off) because the insurance company wanted to know why it was there and would not insure me until they knew... (on the record it doesn't disclose the exact reason why you got it).
Tried another insurance company (State Farm) and had to jump through hoops to prove that that was the only thing on my record (5 year abstract). They wanted to know why I got the administrative suspension...After speaking with the FSCO, Etc. I was informed that I don't have to disclose why. They explained that there are numerous things that can cause an admin suspension. but to keep in mind it is an immediate cancellation if I'm found lying.
My suspension was tied in to me not having a valid tag (got pulled over for that) that led into the admin suspension for Warn range. So I omitted the last part.
sum it up... if your going to new insurance you may have so explaining to do.. but for your current one... I didn't have any problems.... for the next 5 years after that suspension my Car insurance never went up nor did they ask me about it...
I hope you learned from this experience... even if you have one don't drive.... I was in my 30's went I had this happen and now I don't touch my keys if I have even one beer.
