Alaska Road Sign Practice Test

How road signs are tested in Alaska

Road sign questions are part of the Alaska written knowledge test (20 multiple-choice questions, 16 right to pass). Know the signs well and those questions become easy points.

Signs from the Alaska Driver Manual (REV. 10/2025). What every kind of sign means, by shape and color: our road sign guide.

Signs the Alaska Driver Manual adds

• Signs

  A lane-reduction sign showing the right edge moving in means the road narrows ahead: merge left. p. 45

• Signs

  A low clearance sign (for example 12'-6") means vehicles taller than the clearance must take another route around it. p. 46

• Slow moving vehicle emblem

  The slow-moving vehicle (SMV) emblem is required on all slow-moving vehicles, those that go 25 mph or less. p. 54

  A speed limit is the maximum speed in ideal conditions; slow down for hills, curves, bad weather and other hazards. p. 34

• DO NOT ENTER SIGN • red and white

  The Do Not Enter sign faces traffic entering a road or ramp the wrong way; a white-on-red WRONG WAY sign may be placed further along the wrong direction. p. 44

• Signs
