According to the driving characteristics of the vehicle in the overtaking lane, the position of the sighting point of the overtaking lane on the outer side of the center dividing line and its horizontal clearance are analyzed. When the line of sight of the overtaking lanes on the outer side of the central divider of the expressway can not meet the requirements of the codes, solutions and measures for solving the problems are put forward for the design of expressways.
