Adverse Conditions

Reading Police and Marshal Signals

Genuinely useful, specific knowledge most drivers only pick up by accident — here it is directly, from the official handbook.

A traffic police officer's hand signals:

Signal

Meaning

One arm raised, palm facing traffic approaching from behind the officer

STOP — for traffic behind the officer

Both arms raised, palms out

STOP — for traffic from both in front and behind

Arm signal indicating forward movement

Come on — proceed

Arm signal facing oncoming traffic

STOP — for traffic approaching from in front

A beckoning motion

Keep coming — continue toward the officer

Read the palm and the facing, not just the raised arm — the same gesture is addressed to different traffic depending on which side you approach from.

A traffic marshal's signals (typically at pedestrian crossings):

Signal

Meaning

Barrier arm position

Stopping pedestrians from crossing

Ready stance

Ready to let pedestrians cross — vehicles must be prepared to stop

Arms extended, blocking

All vehicles must stop

Relaxed stance

Not ready to let pedestrians cross

(Seed both as tables.)

The skill underneath both tables: an officer's signal is directional. The same raised arm means stop for you or nothing for you depending on which side of the officer you're approaching from — so read the palm and the facing, not just the raised arm.

Key takeaways

  • One arm raised = stop for traffic behind the officer · both arms raised = stop for both directions · beckoning = keep coming — read the palm and facing, not just the arm
  • A traffic marshal's arms-extended block stops all vehicles; a ready stance means be prepared to stop for pedestrians

Quick check

A police officer stands in the junction with both arms raised, palms facing outward. What does it mean for you?
