Question: What is the minimum safe following distance you should maintain behind a large truck in ideal dry conditions on a highway travelling at 100 km/h?
Answer options:
- 2 seconds
- 3 seconds
- 4 seconds ✅ 5 seconds
Correct answer: 5 seconds
Explanation: For the ICBC knowledge test, the correct following distance behind a large truck on a highway is five seconds. Under ideal conditions, while a standard vehicle requires a three-second gap on high-speed roads, large trucks severely block your line of sight and have much longer stopping distances, requiring you to increase this cushion to five seconds. Shorter intervals like two, three, or four seconds are incorrect because they fail to provide adequate reaction time or visibility if the truck brakes suddenly. Understanding these variable following distances is highly relevant for Class 7 applicants, as space margin rules are frequently tested.
