Within Colorado, Fort Collins is the least expensive neighborhood, with an average annual insurance rate of $921, well below the state average. Aurora, Loveland, and Longmont are also extremely affordable auto insurance neighborhoods, with average annual insurance rates of $934, $990, and $1002, respectively. Boulder, Estes Park, and Aspen are also relatively cheap, with average insurance rates of $1035, $1053, and $1076, respectively.

Colorado classifies alcohol-related offenses into two categories: driving while ability is impaired by alcohol or drugs (DWAI) and driving under the influence of alcohol or drugs (DUI). A person who drives with a blood alcohol concentration (BAC) between 0.05% and 0.07% is considered to be driving while ability is impaired by alcohol or drugs (DWAI), and any higher than that is considered DUI. DUI entails heavier fines, more jail time and automatic license suspension.
Both alcohol-related offenses have a huge impact on insurance rates. In Fort Collins, a DWAI will result in your premium going up to $1713 per year. This is higher than the insurance rates in Denver, the most expensive neighborhood. In Estes Park, an alcohol-related offense could increase your premium to $1959. In Longmont, a single alcohol-related offense could increase your insurance rates from $1002 to a whopping $1864. Most insurance companies will keep your rates high for at least three years after your first conviction.
Taking a defensive driving course could help lower your premium. In Fort Collins, this would help bring your premium down to $1456, in Longmont to $1584 and in Estes Park it would bring your premium down to $1665.
