1、客体要件

（1）本罪侵犯的客体是公共安全，主要是指船只、汽车的交通运输安全和不特定多数旅客的生命、健康及财产安全。本罪的犯罪对象只能是船只、汽车。船只、汽车是大型的现代化交通运输工只，与公共安全联系密切。劫持这类交通工具，就有可能危害船只、汽车的交通运输安全和不特定多数旅客的生命、健康及财产安全，造成人员伤亡和财产毁损。

（2）本罪侵犯的对象，是船只、汽车。船有机动船和非机动船之。这里所说的船只应理解为机动船，非机动的木帆船、牛皮划等小船遭受侵犯虽也可造成损失，但一般不危害公共安全。

1. Object element

(1) The object of this crime is public safety, which mainly refers to the traffic and transportation safety of ships and cars and the life, health and property safety of the unspecified majority of passengers. The object of this crime can only be ships and cars. Ships and cars are large modern transportation workers, closely related to public safety. The hijacking of such means of transport may endanger the safety of transportation of ships and cars and the safety of the lives, health and property of the unspecified majority of passengers, causing casualties and property damage.

(2) The object of this crime is ships and cars. There are motor boats and non-motor boats. The ship mentioned here should be understood as a motor ship. The invasion of non-motor wooden sailboats, cowhide paddles and other **all boats can also cause losses, but generally does not endanger public safety.

2. Objective elements

The objective aspect of this crime is to hijack ships and cars by violence, coercion or other means. Violence refers to binding, beating and injuring people on ships and cars, especially drivers and ticket sellers, to force ships and cars to change direction or control aircraft by themselves. Coercion is to impose mental intimidation and coercion on the crew, such as threatening by car or ship, so that the driver and operator dare not resist, and obey their command or control the driving by themselves. Other methods refer to any other hijacking methods other than the above-mentioned methods of violence and coercion, such as the use of ********s to make the driver drunk and faint, so that the driver is in a state of no resistance or no resistance, so as to achieve the purpose of hijacking ships and cars. The hijacking here refers to the behavior that criminals use the above-mentioned means to forcibly control ships and cars according to their will. The crime of hijacking ships and cars is an act crime, not a result crime. As long as the perpetrator commits the act of hijacking a ship or car by violence, coercion or other means, it will constitute an accomplished crime, regardless of whether the criminal purpose is achieved.

3. Main elements

The subject of this crime is the general subject. Any natural person who has reached the age of criminal responsibility and has the capacity of criminal responsibility can constitute a crime. It can be composed of Chinese, foreigners or stateless persons. For example, foreign ships, cars and planes entering China also constitute the crime of hijacking ships and cars.

4. Subjective element

The subjective aspect of this crime is intentional crime, but there is no requirement for the purpose of the crime. The perpetrator hijacks cars and ships, regardless of the purpose, will not affect the establishment of this crime.
