An SR22 is a type of insurance that you may be required to carry in some states. Generally you have to carry this if you were in an accident and at the time of the accident had no insurance. You may also have to have one if:DUI or DWI or any serious moving violation, license suspension, and too many tickets in a short span of time. You will most likely have to keep the sr22 for 3 years but once it is in place and filed with your state you can begin to drive legally again. If you move to anothe state you must continue the sr22 even if your new state does not require one.
