How many people can ride in a Honda CR-V?

Can it fit 8 people?

You can take as many people as there are seats in the car. To take more people is illegal. The Honda CR-V has 5 seats.

Why don't you just go to a Honda site and read the specs?

Looks like 5

Take a look inside. There will be one seat belt for each allowed passenger. If I remember correctly, there are five.

No, you can't ( legally ) fit 8 people in any generation CR-V.

Count the number of seat belts, that is the maximum number of people.
