Question: In Quebec, what speed rule applies in a construction zone with workers present?

Answer options:

• Standard 50 km/h applies ✅ fines are typically doubled
• There is no specific rule
• Posted speed always applies

Correct answer: fines are typically doubled

Explanation: Under the Quebec Highway Safety Code, traffic fines are doubled for speeding in active construction zones when workers are present to ensure worker safety. Standard speed limits do not automatically default to fifty kilometers per hour, specific legal rules definitely exist, and merely stating the posted speed applies ignores the severe penalty multiplier triggered by worker presence. Knowing this rule is highly relevant for the SAAQ Class 5 knowledge test, which frequently evaluates driver awareness of doubled fines and safety protocols in orange-sign construction zones.
