Question: When passing a stopped emergency or tow vehicle with flashing lights on a road with a limit of 100 km/h, you must slow down to no more than:

Answer options:

  • 30 km/h
  • 60 km/h ✅ 70 km/h
  • 80 km/h

Correct answer: 70 km/h

Explanation: Quebec's safety corridor rule (corridor de sécurité) requires drivers to slow down and change lanes when approaching a stopped emergency or tow vehicle with flashing lights. On a 100 km/h highway, reducing your speed to a maximum of 70 km/h provides a safe buffer for personnel on the shoulder. Options like 80 km/h are too fast to ensure roadside safety, while 30 km/h or 60 km/h are excessively slow, creating rear-end collision hazards on fast-moving highways. Understanding these speed reduction rules is critical for the SAAQ knowledge test, as safety corridor violations carry heavy fines and demerit points.
