An officer with their arm raised vertically requires all road users approaching the officer to stop, except for drivers who cannot do so with sufficient safety. If this signal is made at an intersection, it will not require drivers who have already entered it to stop.
When the officer has one or both arms extended horizontally, it requires users approaching the officer from any direction that crosses the direction indicated by the extended arm or arms to stop, regardless of their direction of travel, and remains in force even if the officer lowers their arm or arms, as long as they do not change position or make another signal.

If the officer swings a red or amber light, it requires road users towards whom the officer directs the light to stop. (Photo 2)
If the officer extends their arm and moves it alternately up and down, it requires drivers approaching the officer on the side corresponding to the arm making the signal, and perpendicular to that arm, to reduce their vehicle's speed. (Photo 3)
