The City Traffic Engineer is hereby authorized
to determine those intersections at which drivers of vehicles shall
not make a right, left or U-turn and shall place proper signs at such
intersections. The making of such turns may be prohibited between
certain hours of any day and permitted at other hours, in which event
the same shall be plainly indicated on the signs or they may be removed
when such turns are permitted.
Whenever authorized signs are erected indicating
that no right or left or U-turn is permitted, no driver of a vehicle
shall disobey the directions of any such sign.
The driver of any vehicle shall not turn such
vehicle so as to proceed in the opposite direction upon any street
in a business district and shall not upon any other street so turn
a vehicle unless such movement can be made in safety and without interfering
with other traffic.
