Traffic lights and pavement markingsQuestion 157 of 318

The traffic lights at an intersection do not work, and no other sign replaces them. What must you do?

  1. Go first if you are on the wider road
  2. Treat the lights as flashing yellow lights
  3. Stop and wait until the lights work again
  4. Treat the intersection as if every direction had a stop sign
Show answer

Correct answer: Treat the intersection as if every direction had a stop sign

Treat an intersection with broken lights as an all-way stop. Every driver stops and then goes in turn.
