When turning right with a long vehicle or combination truck-trailer, what is the recommended approach if you cannot stay in the proper lane?

The recommended approach of staying about 4 feet from the curb when turning right with a long vehicle or combination truck-trailer is important for several reasons. Long vehicles require a wider turning radius due to their length. Staying a safe distance away from the curb helps ensure that the trailer does not strike the curb, which could cause the trailer to swerve or get stuck, potentially leading to accidents or damage.

Positioning the vehicle approximately 4 feet from the curb allows for a safer turning trajectory, minimizing the risk of clipping obstacles or pedestrians that may be present. This approach also enhances the driver's ability to maintain control throughout the turn by providing the necessary space for their trailer to move through the turn without obstruction.

Being cautious in this situation is essential for the safety of all road users, as it increases visibility and gives the driver enough space to navigate the turn effectively.
