1. While driving in a flex lane bordered by double dashed yellow lines, the overhead signal above your lane shows a red X. What must you do?

  2. Continue driving; the X marks an emergency stopping area only
  3. Proceed only if you are turning left
  4. Slow to the posted advisory speed and continue

Answer: A — You may not use the lane; move to another lane

A red X over a flex lane means the lane is closed to you and you may not enter or continue in it.

  1. One second
  2. Four seconds
  3. Two seconds

  1. Four or more
  2. Two or more
  3. One
  4. Three or more

Answer: B — Two or more

The express lanes are free for vehicles carrying two or more people, along with motorcycles, buses and C-decal vehicles.

6. The signals at a single-point urban interchange lose power during an outage. How should a driver treat the intersection?

  3. Proceed with extreme caution and courtesy
  4. Wait for a police officer before entering under any circumstance

Answer: C — Proceed with extreme caution and courtesy

A powered-down single-point urban interchange is specifically not treated like a four-way stop; drivers proceed carefully, and most have battery backup anyway.

  2. The driver on the right
  3. Whichever vehicle is larger

  4. When safe, turning left from a one-way street onto a one-way street
