Traffic officer signals mean the following:

• Arms extended to the sides or lowered:
• From the left and right sides: Trams may drive straight. Other vehicles may drive straight and turn right. Pedestrians may cross the roadway;
• From the front (chest) and back: All vehicles and pedestrians must stop.

Right arm extended forward:

• From the left side: Trams may turn left. Other vehicles may drive in all directions;
• From the front (chest): All vehicles may only turn right;
• From the right side and back: All vehicles must stop;
• Pedestrians may cross the roadway behind the traffic officer's back.

Arm raised straight up:

• All vehicles and pedestrians must stop and not move in any direction. This does not apply to cases described in paragraph 6.14 of the Traffic rules.
• The traffic officer may use other hand signals that drivers and pedestrians can understand.

To make signals easier to see, the traffic officer may use a baton or a disk with a red reflector.
