Depending on the country and even on the region, gestures during the voting of a machine can carry different meanings. Therefore, experimenting with gestures is not worth it. To stop the car, just wave your hand.
Instruction manual

It is best to start voting when you are in the driver’s field of view. Then you need to smoothly and confidently raise your hand and vote. The driver will notice movement, that is, a raised and waving hand, than something static on the road, when the voter raises his hand and stands, not moving, regardless of whether or not a car passes by him. Voting, you need to look at the driver, not looking away.

Be attentive to the part of the road on which you intend to vote. So, cars cannot stop on the bridge. A stop on the road without a curb can trigger an accident. It is also undesirable to vote where there is a narrowing of the road or a sharp turn, or repair work. When voting, you need to stand on the side of the road so that the outstretched hand does not interfere with the passage of cars. Closer to stand is more dangerous, further - the driver may not notice you.

If in the evenings you often have to get home on the way, make sure that your clothes have reflective inserts. So you will be more noticeable on the road. It is both safer and more effective for voting on the road. After all, the fact that the voter sees the car does not mean that the driver of the car sees the voter.

Even if you need to leave very urgently, do not take extreme measures and do not jump out directly onto the road. The driver may not notice you in time, do not have time to react and slow down. Understand that the machine will not stop instantly. The braking distance at a speed of 60 km per hour is about 30 meters. And if you jump onto the road for, it would seem - sufficient, 10 meters to the car, the chances of not being shot down will be small.
