Studies reveal that between ages 30 and 50, men pay slightly less auto insurance than women do. Married car owners also are charged with less insurance premiums, they tend to be more careful now that they are driving for their families.
The Mexican government requires that tourists get auto liability insurance from a Mexico-based insurance company.
