Sample questions

In every state except Utah, a driver aged 21 or older is legally impaired 'per se' at or above what blood alcohol concentration?

  1. 0.02 percent
  2. 0.10 percent
  3. 0.08 percent
  4. 0.15 percent
Show the answer

C. 0.08 percent

All states but Utah set the per se limit for adult non-commercial drivers at 0.08 percent (Utah uses 0.05). The 0.10 figure is an older limit that no state uses today.

An oncoming driver fails to dim blinding high beams at night. Where should you look?

  1. Straight ahead at the oncoming lights
  2. Down at your instrument panel
  3. Into your inside rear-view mirror
  4. Toward the right edge of your lane
Show the answer

D. Toward the right edge of your lane

Looking toward the right edge line or the edge of the road lets you keep your lane while avoiding the glare. Staring at the lights blinds you for several seconds, and flashing your own high beams back only blinds both drivers.

Reference: State driver's manual, night driving

Several vehicles approach an all-way stop from different directions at different times. Who goes first?

  1. The vehicle that is travelling on the wider street
  2. The vehicle that is going straight ahead rather than turning left
  3. The vehicle that reached the intersection and stopped first
  4. The vehicle that has the most passengers on board
Show the answer

C. The vehicle that reached the intersection and stopped first

At an all-way stop, drivers go in the order they arrived after each makes a full stop. Street width and passenger count have no bearing on right of way.

Reference: Uniform Vehicle Code, Chapter 11 (Rules of the Road); state driver's manual

A five-sided sign shaped like a house (pentagon) warns of what?

  1. A railroad crossing a short way ahead
  2. A no-passing zone on a hill
  3. A school zone or school crossing
  4. A county or state border ahead
Show the answer

C. A school zone or school crossing

The pentagon is used for school advance warning and school crossing signs, so watch for children and slow down. Railroad advance warning uses a round sign, not a pentagon.

Reference: MUTCD 11th Edition, Part 7 (Traffic Control for School Areas); state driver's manual, traffic signs chapter

Traffic around you is moving 10 mph over the posted speed limit. What is true about keeping up with it?

  1. It is legal as long as everyone does it
  2. It is legal in the left lane only
  3. It is still speeding and you can be ticketed
  4. It is required so that you do not block traffic
Show the answer

C. It is still speeding and you can be ticketed

The posted limit applies no matter what other drivers are doing; 'going with the flow' above the limit is still a violation. If others want to go faster, keep right and let them pass.
