Must-know rules

Alaska is outside IFTA and the Whittier tunnel bars placarded hazmat loads, so the state's own rules matter more here than for most carriers. I could not confirm current truck speed limits, idling limits, handheld-phone rules or any weight-distance tax from official sources, so those topics are left out.

• Must knowWeigh stations: who must stop

  Every commercial vehicle or combination with a GVWR of 10,001 lbs or more must stop at any open weigh station or open roadside inspection site. The state's rule is to stop where an official highway sign says a station is operating, or when an officer directs you.

• Must knowOversize/overweight permits: when needed

  A permit is required when the vehicle or load exceeds the maximum dimensions or weights in 17 AAC 25 and will use a public road. Permits are issued for non-divisible, non-standard vehicles and loads. They are not issued to increase payload or to get around the legal size and weight limits.

Weight limits, oversize permits and chain laws

Alaska's legal limits are 8.5 ft wide and 15 ft high. Its tandem-axle limit is 38,000 lb, not the federal 34,000 lb, and no fixed gross-weight cap is stated in the sources I found. I found no truck chain-carry season. Chains and studs are instead banned on paved roads in summer. Spring-breakup weight cuts of up to 50% are the biggest seasonal risk.

Weight limits

20,000 lb single axle, 38,000 lb tandem
Alaska's 38,000 lb tandem and 42,000 lb tridem limits are above the federal 34,000 lb tandem figure. The rule's table also lists 50,000 lb for a 4-axle group. FHWA says Alaska has no stated gross-weight cap. Gross weight is set by the bridge formula and the axle-group limits. With the 53-ft trailer limit, the practical limit for a 5-axle tractor-semitrailer is 80,000 lb. Alaska also allows long co
A permit is needed when a vehicle or load exceeds the weights in 17 AAC 25. Permits are for non-divisible loads only. They are not issued to increase payload or gain a competitive advantage. Overweight permits require an exact route. The single-trip fee is a $40 base charge, plus $25 if gross weight is 150,000 lb or more (17 AAC 25.380). Extended and annual permits also exist; fees and the 125% ca Source

Legal size without a permit

8 ft 6 in wide, 15 ft high, 53 ft semitrailer
Single-trip oversize permit: $40 from Alaska DOT&PF, Division of Measurement Standards & Commercial Vehicle Compliance (MSCVC), Commercial Vehicle Customer Service Center, 11900 Industry Way, Buildi
Official permit manual: overwidth moves are daylight-only unless equipped with proper lighting and retroreflective tape. They are also subject to weekend and holiday restrictions printed on the permit. Loads over 10 ft 6 in wide, up to 12 ft, need at least one pilot/escort on all routes. Single-trip permits are 3 days, or 5 days if the trip is over 400 miles one way. Some other websites say 'no Su Source

Chain law

No chain law for trucks
I found no Alaska rule that trucks must carry chains in a season, and no official statute requiring chains when signs are posted. A trucking-association chain-law summary says there is no requirement for trucks to carry chains during any specified period. It is dated 2016, so verify. Chains are actually restricted: AS 28.35.155 bans tires with chains or studs on paved roads in summer. North of 60° Source Non-government source

• Must knowSpring-breakup seasonal weight restrictions

  DOT&PF imposes seasonal weight limits on vehicles over 10,000 lb GVW. They are stated as a percentage of legal axle loading under 17 AAC 25.013(e). They typically occur between March and June and can cut allowable gross weight by up to 50%. All state routes may be subject to them, and they are posted on the MSCVC website.

Fees and DOT requirements

Alaska commercial truck registration is based mainly on the truck's unladen (empty) weight, not its gross weight, so the 26,001 lb and 80,000 lb figures don't map directly to a fee. Alaska does not take part in the International Registration Plan (IRP). Official sources I could find don't state a state operating-authority fee for for-hire intrastate carriers, and I could not confirm whether such authority is required.

Class B CDL

$100 for 5 years (about $20 a year)
The official DMV table lists the CDL and CDL renewal at $100 standard or $120 REAL ID, for Classes A, B and C. The commercial road (skills) test is $25. The official fee page I saw does not list separate endorsement or knowledge-test fees, so I give none (null). The $15 commercial learner's permit f Source

Class A CDL

$100 for 5 years (about $20 a year)
Same fee table as Class B: $100 standard or $120 REAL ID, for issue or renewal. $25 commercial road test. No separate endorsement or knowledge-test fees are stated on the official page (null). The 5-year validity is from a non-official source and is unconfirmed, as with Class B. Source

How registration is figured

Commercial vehicle fees are primarily based on unladen weight under AS 28.10.421(c). The biennial tiers are $180 (up to 5,000 lb), $268 (5,001–12,000), $516 (12,001–18,000) and $662 (over 18,000). Registration is normally for 24 months, but commercial vehicles may choose 12 or 24 months. If 12 month
The fee schedule uses empty weight, not gross weight, so I cannot give an exact dollar figure for a 26,001 lb straight truck or an 80,000 lb combination. If the power unit's unladen weight is over 18,000 lb, the top tier applies: $662 for 24 months, or about $331 for 12 months. Lighter empty weights fall into lower tiers. A trailer is a separate registration; older statute text and secondary sourc Source

Intrastate operating authority

Not confirmed. I found no official source naming a state operating-authority certificate or permit for for-hire intrasta. unknown (no fee or renewal schedule found), depends on the type of operation; see source.
A compliance-service summary says Alaska does not require exempt carriers operating intrastate to obtain a permit for operating authority. That summary covers exempt carriers only, not necessarily all for-hire carriers. It says intrastate exempt carriers with vehicles over 10,000 lb unladen weight must file proof of insurance ($500,000 bodily injury and $200,000 property damage, or $700,000 combin Source Non-government source

State DOT requirements

• Must knowIntrastate USDOT number

  A motor carrier operating only in intrastate commerce must file a Form MCS-150 with FMCSA and receive an intrastate USDOT number before beginning operations. The carrier must display the number on each self-propelled commercial motor vehicle, with the additional marking information required by 49 CFR 390.21.
