If a trailer is 3000 lbs or less, the combination must stop within what distance at 20 mph?

When determining stopping distances for a combination vehicle, regulations set specific requirements based on the weight of the trailer. For a trailer weighing 3000 lbs or less, the law states that the maximum stopping distance at a speed of 20 mph should not exceed 40 feet. This measurement ensures that vehicles can stop safely and effectively, reducing the likelihood of accidents due to insufficient stopping power.

Factors influencing this standard include vehicle design, weight distribution, and braking efficiency. Stopping distances are crucial for maintaining safety on the road, especially in environments with unexpected obstacles or conditions that may necessitate sudden braking.

While other distances are presented in the options, they exceed the legal requirement established for this scenario, making them less appropriate. Compliance with the 40 feet stopping distance ensures that drivers remain within safe operational limits for their vehicle type and load.
