Sec. 18-53. Limitations on privilege of overtaking and passing.[207]
The driver of a vehicle shall not drive to the left side of
the center line of a street in overtaking and passing another
vehicle proceeding in the same direction unless such left side
is clearly visible and is free of oncoming traffic for a sufficient
distance ahead to permit such overtaking and passing to be
made in safety.
No person operating a truck or tractor and trailer shall
pass or attempt to pass any truck or tractor and trailer going
in the same direction on an upgrade hill if such passing will
impede the passage of following traffic. (Code 1959, § 18-53.)
