On some roads, there is a margin or side space on the road, and this space cannot be parked in it except for reasons beyond your control.

You can use the side of the road if there is a breakdown in your car, or if there is a car behind you that wants to pass you, or if you want to turn right, and so on.

If you enter the side of the road and want to return to the road again
 You must give priority to all traffic coming from behind you
 You must look in the mirror at the left and dead angle and give a dimple to the left before entering the road again.
 
 If your car tires go off the edge of the road for some reason, the situation is dangerous and you must act calmly and immediately
 You must let go of the accelerator pedal, steer the car toward the road calmly, and beware of quick movements with the steering wheel.
 
 In the dark, it is inappropriate to drive on the side of the road because the vision ahead is not clear
 Even if this is to facilitate the process of overtaking those behind you, because the side of the roads may be crossed by bicycles or pedestrians, and it is not safe.
 
 I must also point out that there are columns on the margins of the roads or on the sides of the roads
 Some of them are red and some are white with a specific sign or drawing inside them, including the following:

The first picture

Now you must memorize these drawings because they were mentioned in the theoretical exam.
 These poles carry reflectors in the dark to facilitate spotting the road and the edge of the road

• The white column on the right has a black line with a | sign inside it  It is placed on the right and means that you are moving in the right direction.
• The white column on the left side has a black line inside it: it is placed on the left and means that the other field is for the opposite lane.

Second picture

These red poles, which carry a white reflective sign in the dark, show where the edge of the road is so that the driver does not approach it if the ground is covered with snow and the road is not clear and the edge of the road or the edge of the road is not visible to the driver.
 
 Roads may not contain lines that clarify or separate driving lanes, whether in the middle or on the edges of the road.
 This is why you must drive your car on the right and not in the middle of the lane
 If the road is wide and does not contain white lines on the ground
