Will Diabetes Affect My Car Insurance? 
Most companies will have a medical question referring to it or similar . Had a customer black out due to low blood sugar and carrier was refusing to pay due to disclosure failure . Had another customer who was blind in one eye . That carrier did not have a medical question about that -LRB- only diabetes -RRB- . customer never had a wreck with the good eye ... can not say the same for the other . He said it was not his fault he did not see it coming -LRB- did not turn his neck far around enough to look -- carrier did pay . Usually if the car is adapted for a disability no problem . They have not figured out how to adapt for blackouts for high or low sugar.Did have one customer upset that a carrier would not insure her , she explained that she only had seizures at night and saw no reason why she could not drive in the daytime .
