What it means
Traffic officer hand signal (SS1): arm extended horizontally. Traffic approaching from behind the officer must stop and remain stationary until signalled to proceed.
What to do
- Stop even though the officer faces away; the extended arm covers your approach.
- Remain stationary until the officer signals you to proceed.
In the K53 test
Officer signals outrank lights and signs. From the rear you stop on the arm position, not on whether the officer is looking at you.
Where you will see it
Wherever a traffic officer is directing traffic; their signals outrank lights.
