What "Alaska traffic law" actually covers
Alaska's vehicle code regulates speed, right-of-way, signaling, lane use, parking, equipment, insurance, alcohol, and the documents you must carry while driving. Most of the questions on the Alaska permit exam come from a few sections of that code — speed and right-of-way alone account for nearly a third of the test. The Alaska DMV publishes a free PDF handbook that summarizes the relevant sections in plain language; this page condenses the parts that show up on the knowledge test.
Speed limits at a glance
In Alaska, expect 65 mph on rural Interstates, 55 mph on urban Interstates, 25 mph in residential areas, and 20 mph in marked school zones when children are present. The basic speed law overrides every posted limit: you must drive at a speed that is reasonable for the weather, traffic, road, and visibility — even if that means going well below the posted number in fog or heavy rain.

Right-of-way essentials
At a four-way stop the first vehicle to arrive proceeds first; if two arrive together, the one on the right goes. At an uncontrolled intersection, yield to any vehicle already in the intersection and to the vehicle on your right when arrivals are simultaneous. Pedestrians in any marked or unmarked crosswalk always have right-of-way in Alaska, and emergency vehicles with lights and siren require you to pull to the right and stop.
Alcohol, drugs, and implied consent
The legal BAC limit in Alaska is 0.08% for drivers 21 and older, 0.02% for drivers under 21, and 0.04% for any driver operating a commercial vehicle. By accepting a Alaska driver license or permit you give implied consent to chemical testing — refusing the breath, blood or urine test triggers an automatic license suspension separate from any DUI conviction.
Phones, seat belts, and child seats
Handheld phone use while driving is illegal in Alaska. Texting while driving is illegal for all drivers regardless of age. Seat belts are required for primary enforcement for all front-seat occupants. Children must be in an approved restraint until they meet the Alaska height-and-weight thresholds — currently required for children under 8 or under 4'9".
