When must you NOT open the door of your motor vehicle?

If it's likely to hit someone or something, such as a cyclist

When the car is moving

If you are less than 10 meters away from a bus stop

When you are asked to get out of the car by a police officer

When stopped on the right on a one-way street

The correct answer is: If opening the door would result in a collision with other people or objects, such as cyclists. The importance of this rule lies in ensuring the safety of all road users. Failing to pay attention to the surroundings when opening a car door can lead to what is known as a "dooring accident," where the action of opening the door forces cyclists or other passersby to suddenly swerve, potentially resulting in a collision with the door or other objects. Such accidents can cause physical injuries to cyclists and increase the risk of traffic accidents. Therefore, this regulation is significant for protecting vulnerable groups on the road.
