  • A completed driver medical report form is required for Class 4, and a registry agent checks your vision at the counter.

AlbertaRules of the road

Your paying passenger is belted in, and you are ready to pull your taxi away from the curb into moving traffic.

  1. Pull out briskly so following drivers have time to adjust
  2. Signal, check your mirror and over your shoulder, then wait for a gap you do not have to force
  3. Signal and move out because traffic must yield to a taxi leaving the curb
  4. Remain stopped until another driver waves you into the traffic lane

The answer is B

You must signal, check the mirror and blind spot over your shoulder, then wait for a safe gap before leaving the curb. This lets you find cyclists and vehicles beside the taxi and keeps moving traffic from braking or swerving to avoid you. A signal shows your intention, but it does not require another driver to yield.
