What is the maximum stopping distance required for combination vehicles weighing more than 3,000 pounds when traveling at 20 mph?

The maximum stopping distance for combination vehicles weighing more than 3,000 pounds traveling at 20 mph is 40 feet. This figure is derived from safety regulations that account for the increased weight and complexity of combination vehicles, which can include tractor-trailers and other large configurations.

At higher speeds and heavier weights, it takes longer for a vehicle to stop due to inertia and the greater momentum involved. Regulatory guidelines have set this distance to help ensure that these vehicles can safely stop within a certain range under ideal conditions, thus providing a standard for drivers and ensuring safety on the road. Therefore, recognizing this maximum stopping distance is crucial for safe driving practices, especially for larger vehicles that require more time and distance to brake effectively.

This understanding is vital for drivers who operate these vehicles, as it directly impacts their ability to react to road conditions and avoid potential hazards.
