Taxis, ambulances, emergency and tow vehicles: key rules to remember

Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗

Ch. 1 Licence Class 4 and Class 5 (pp. 5–7)

  • Class 4 covers ambulances used for hire, taxis and rideshare vehicles carrying 9 or fewer, and buses or PB/PC vehicles carrying 24 or fewer.
  • Taxi, limousine and rideshare drivers file a criminal record check with the company every year; an unsatisfactory check can bring a T restriction: no passengers for hire.
  • An experienced Class 5 driver may drive a taxi or rideshare vehicle seating 10 or fewer with two years post-GDL experience and a satisfactory record (under 12 points in two years, no impaired-driving suspension in 10 years).
  • Taxis, limousines and rideshare vehicles need a PMVI inspection every 12 months.
  • Taxis, ambulances, police vehicles and vans should keep at least a three-second following distance.

Emergency vehicles (pp. 131–132)

  • Emergency vehicles: police, firefighting (including municipal fire pumpers) and ambulances.
  • Normal rules of the road are suspended only while responding to a call (or chasing a suspect in a serious crime) and only while continually using siren and flashing lights.
  • Emergency drivers must still use due care and remain responsible for safe operation; they must not use the exemption when not on an emergency.
  • Other drivers must yield to an emergency vehicle with lights and siren, pull parallel to the right edge, and if in an intersection clear it and stop beyond.
  • Do not assume other drivers have seen or heard you; in cold weather with windows closed, sirens are hard to hear.
  • Drivers must slow to 60 km/h when passing a stopped emergency vehicle with flashing lights, unless it is on the other side of a divided highway.

Recovery vehicles (tow trucks) (pp. 132–133)

  • Use the tow truck's flashing lights only when the tow truck or the vehicle being helped is a hazard or obstruction.
  • A vehicle in tow needs temporary tail, brake and signal lights at its rear.
  • Flashing lights give a tow truck no special right-of-way privileges.
  • Remove wrecked vehicles and clean up collision debris; post a flagperson if a tow line crosses the highway.
  • Towing that makes the combination longer than the legal length needs a permit.
  • Drivers must slow to 60 km/h passing a stopped tow truck or service vehicle with amber, or amber and blue, flashing lights, unless it is across a divided highway.

Taxis (pp. 133–134)

  • Taxis travel about 64,000 km a year, close to four times the average car.
  • Pressures include radios and meters, emergencies, passengers urging speed, and unruly or intoxicated passengers.
  • Speeding and ignoring traffic controls in heavy traffic saves only a few minutes.
  • A taxi driver must obtain a criminal record check.
  • Check the vehicle before a shift; report defects to the dispatcher, and have a seriously defective taxi towed rather than driven.
