If the president and vice president die in a car crash, he would lead the country according to the 25th amendment?

No, the 25th Amendment to the United States Constitution does not specifically address the scenario where the President and Vice President both die in a car crash. However, the 25th Amendment does provide guidelines for presidential succession and the filling of a vacant Vice Presidential position.

According to the 25th Amendment, if the President is unable to fulfill their duties, the Vice President becomes the President. In the case of the Vice President's position being vacant, the President must nominate a Vice President who is then confirmed by a majority vote in both the House of Representatives and the Senate.

If both the President and Vice President were to die in a car crash simultaneously, the line of presidential succession beyond the Vice President would come into play. The order of succession is as follows:

1. Speaker of the House of Representatives
2. President pro tempore of the Senate
3. Secretary of State
4. Secretary of the Treasury
5. Secretary of Defense
6. Attorney General
7. Secretary of the Interior
8. Secretary of Agriculture
9. Secretary of Commerce
10. Secretary of Labor
11. Secretary of Health and Human Services
12. Secretary of Housing and Urban Development
13. Secretary of Transportation
14. Secretary of Energy
15. Secretary of Education
16. Secretary of Veterans Affairs
17. Secretary of Homeland Security

So, if both the President and Vice President were to die, the Speaker of the House would be next in line to lead the country, according to the order of succession established by law.
