Alaska waives the road skills test and Entry Level Driver Training for a commercial driver license if your military job involved driving a military vehicle like the class of commercial vehicle you are applying for. The CDL knowledge tests cannot be waived, and you cannot transfer school bus or passenger endorsements.
Complete the Alaska Division of Motor Vehicles application for a military skills test waiver. Page two has to be signed by your commanding officer. The DMV commercial driver license page explains the rest of the process.
The waiver application signed by your commanding officer, and documentation that you are currently licensed on, or were employed within the last year in, a military position operating that class of vehicle.
