Gender
Men average more miles driven per year than women do, and consequently have a proportionally higher accident involvement at all ages. Insurance companies cite women's lower accident involvement in keeping the youth surcharge lower for young women drivers than for their male counterparts, but adult rates are generally unisex. Reference to the lower rate for young women as "the women's discount" has caused confusion that was evident in news reports on a recently defeated EC proposal to make it illegal to consider gender in assessing insurance premiums. Ending the discount would have made no difference to most women's premiums.
Age
Teenage drivers who have no driving record will have higher car insurance premiums. However, young drivers are often offered discounts if they undertake further driver training on recognised courses, such as the Pass Plus scheme in the UK. In the U.S. many insurers offer a good grade discount to students with a good academic record and resident student discounts to those who live away from home. Generally insurance premiums tend to become lower at the age of 25. Senior drivers are often eligible for retirement discounts reflecting lower average miles driven by this age group.
Marital status
Drivers who are unmarried are often charged higher insurance premiums as opposed to married drivers.
Vehicle classification
Owners of sports cars, muscle cars, some sport utility vehicles, and motorcycles would have higher insurance premiums as opposed to compact cars, midsized cars, or luxury cars. However, in the case of motorcycles, the chance of causing extensive damage to other vehicles is relatively low (as opposed to damage to oneself) and thus liability insurance premiums are often lower.
