In light of the security situation, the Home Front Command publishes defensive instructions when missiles are fired
When staying outside - lying on the ground saves lives
If we are outside while rockets are being fired and there is no building near us, we must lie down and protect ourselves with our hands on our heads. The reason: reducing the chance of being hit by shrapnel.
Lying on the ground saves life watch
How does lying on the ground during rocket fire save lives?
When a rocket hits the ground, it is better to be as close to the ground as possible and to reduce as much as possible the height of the silhouette of our body and the area of its exposure. This is because most of the warheads of the rockets and missiles have a steel casing, which creates many dangerous fragments in a very dense distribution. These shrapnel directly hit the ground only in a very small area near the place of the explosion, but in most of the area exposed to impact and as you move away from the place of the explosion - the flight path of the shrapnel is diagonal and upwards.

When staying in a vehicle during a warning - stay away from the vehicle
Danger of flaming, broken glass and exposure to shrapnel - even though the vehicle is seen as a relatively protected place, staying in it while missiles and rockets are being fired increases the risk we face.
A large part of our daily routine includes travel. For example, on the way to and from work, dropping the children off at school or classes, visiting grandparents, meeting friends, shopping and hanging out. Even during the firing of rockets or missiles at the residents of the country, it is recommended to maintain your daily routine, in accordance with the instructions of the Home Front Command.
The instructions according to which we must act upon receiving a warning about rocket or missile fire instruct us to stop the vehicles on the side of the road, turn off the engine and get out of it as safely as possible. If there is a nearby building or shelter, which can be reached according to the time of defense in the area where we are staying, we must enter them. If there is no structure or shelter nearby, lie on the ground and protect your head with your hands.

I wrote a number of times. There are no recommendations regarding driving in the city when there is no school to get off and it is dangerous to get out of the vehicle onto the road
