How far should warning triangles be placed from an obstruction?

  1. 15m (49 ft)

  2. 30m (98 ft)

  3. 45m (147 ft)

  4. 60m (197 ft)

The correct answer is: 45m (147 ft)

The correct distance for placing warning triangles from an obstruction is 45 meters (147 feet). This distance is based on regulations that aim to maximize visibility and ensure safety for both the driver setting up the warning triangle and approaching traffic. When placing a warning triangle, it should be far enough away to alert oncoming vehicles of potential hazards without putting the person setting it up in danger. A distance of 45 meters provides a clear line of sight for drivers to see the triangle from a distance, allowing them to react appropriately and safely navigate around the obstruction. While placing the triangle too close, like at 15 or 30 meters, might not give drivers sufficient warning time, placing it further than 45 meters may lead to confusion or reduced effectiveness as the triangle could be less visible or out of context for the situation. Therefore, adhering to the 45-meter guideline strikes a balance between visibility and safety, making it the most appropriate choice.
