Alaska Speed Limits – National Speed Limits in Alaska

In Alaska speed limits for several roads are posted at the maximum speed limit of 65 mph (105 km/h): a majority of the Parks Highway between Fairbanks and Willow (excepting slower zones through Nenana, Denali Park, Cantwell, and Healy), most of the Richardson Highway between Valdez and North Pole, a 35-mile stretch of the Glenn Highway between Wasilla and Anchorage, the Seward Highway freeway in Anchorage between 36th Avenue and Rabbit Creek Road, and other non-freeway parts of the Seward Highway farther south.

The Minnesota Drive Expressway features a 60 mph (97 km/h) speed limit. Engineering studies are needed to define which road segments to post a speed limit higher than 55 mph (89 km/h).

The speed limit in all rural areas of Alaska is 55 mph (89 km/h) unless otherwise posted, and the default limit on a rural two-lane highway is 55 mph (89 km/h). The speed limit when towing a mobile home is 45 mph (72 km/h). Speed limits in Alaska are 15 mph (24 km/h) in alleys, 20 mph (32 km/h) in a business district, 25 mph (40 km/h) in a residential district, and 55 mph (89 km/h) on other roads.

The Alaska Vehicle Code is the rule book for all things having to do with motor vehicles, roads, and, driving. It can be found under Title 28 of the Alaska Statutes.

Most of the lengths of the Interstates in Alaska are not constructed to Interstate Highway standards, but are small, rural, two-lane undivided highways.

Some portions of these highways are built to Interstate standards. The Seward Highway, part of A-3, is built to freeway standards in Anchorage. The Glenn Highway, which is part of A-1, is built to freeway standards from Anchorage to Wasilla. A small portion of the George Parks Highway, A-4, is constructed to freeway standards in Wasilla. In and around Fairbanks, the Richardson Highway, part of A-2, is constructed to freeway standards. In addition to these highways, the Johansen Expressway, in Fairbanks, and the Minnesota Drive Expressway, in Anchorage, are constructed to expressway standards.

Alaska Speed Enforcement

Sec. 28.35.040. Reckless driving.


A person who drives a motor vehicle in the state in a manner that creates a substantial and unjustifiable risk of harm to a person or to property is guilty of reckless driving. A substantial and unjustifiable risk is a risk of such a nature and degree that the conscious disregard of it or a failure to perceive it constitutes a gross deviation from the standard of conduct that a reasonable person would observe in the situation.


A person convicted of reckless driving is guilty of a misdemeanor and is punishable by a fine of not more than $1,000 or by imprisonment for not more than one year or by both.

The Alaska Vehicle Code can also come in handy if you are attempting to settle with an insurance company over a minor traffic accident, or if you received a ticket and wish to go to court rather than simply pay the fine, especially in a case where you feel like you did not break the law.
