What should you do before making a right turn in a tractor-trailer?

Answer: B — Pull your tractor-trailer straight into the intersection

Before making a right turn in a tractor-trailer, it is essential to position the vehicle correctly to navigate the turn safely. Pulling the tractor-trailer straight into the intersection allows the driver to angle the truck properly and ensure there is enough room for the trailer to follow the path of the turn without hitting curbs, pedestrians, or other vehicles. This maneuver aids in establishing a safe turning radius, which is vital due to the length of the trailer and the unique dynamics of larger vehicles. Reducing speed, which is also important, should be done alongside pulling straight into the intersection but is not the primary action before the turn. Signaling is a critical safety step, but signaling and immediately turning without properly positioning the vehicle could lead to dangerous situations, such as running over curbs or colliding with obstacles. Checking mirrors is crucial for awareness, but it should be done in conjunction with other actions to ensure a comprehensive approach to making the turn safely.
