How many passengers can I carry in the car?

In most countries in Europe, it is an offence to carry more passengers in a vehicle than it is intended to carry.   Many countries do not permit children to travel in the frontseat, or if so, only allow them to do so when using a restraint system appropriate to age and / or height. 

NEVER use a rear–facing child restraint system in a front seat where the vehicle is fitted with a passenger airbag.
