What is the maximum speed limit for long combination vehicles?

• A. 90 km/h
• B. 100 km/h
• C. 110 km/h
• D. 120 km/h

Answer: (B)

Long combination vehicles are expected to travel at the same usual highway speed as cars on Alberta roads, which is 100 km/h on most highway sections. This limit is chosen because heavy, long vehicles need more distance to stop and can be less stable in turns or on grades, so keeping within a consistent, lower limit helps reduce risk and keeps traffic moving safely. Always follow the posted speed signs for the road you’re on, and adjust for conditions like weather, road surface, or construction. If a sign specifies a lower or higher limit for trucks, follow that, but the standard maximum for long combination vehicles is typically 100 km/h.
