California Car / Permit practice question · Road Signs

You approach a white rectangular sign reading 'SLOWER TRAFFIC KEEP RIGHT'. What does it tell you to do?

White tall rectangular road sign

Answer choices

  • You may not turn right at this location.
  • Slower vehicles must stay in the right lane so faster traffic can pass.— Correct answer
  • Parking reserved for vehicles displaying a disability permit.
  • Do not enter the road or ramp from this direction.

Why this is the answer

Drivers who go slower than other traffic belong in the right lane, and you should move right when someone close behind wants to go faster. A Slower Traffic Keep Right sign asks for the same behavior. It is not about turning right, parking, or entering a ramp.
