Adult occupant
The passenger compartment of the 208 remained stable in the frontal impact. Dummy readings indicated good protection of the knees and femurs of the driver and passenger. Peugeot showed that a similar level of protection would be provided for occupants of different sizes and to those sat in different positions. In the side barrier test, protection of the chest was adequate and that of other body regions was good. In the more severe side pole test, protection of the chest was marginal. The seat and head restraint provided marginal protection against whiplash injuries in the event of a rear-end collision.

Child occupant
In the frontal impact, forward movement of the head of the 3 year dummy, sat in a forward facing restraint, was not excessive. In the side impact, both dummies were properly contained by the protective shells of their restraints, minimising the likelihood of contact with parts of the car's interior. The passenger airbag can be disabled by means of a switch, allowing a rearward facing child restraint to be used in the passenger seat. However, labelling of the switch positions was not sufficiently clear and the system was not rewarded. There were clear warnings of the dangers of using a reaward facing restraint in that seating position without having deactivated the airbag.

Pedestrian
The bumper provided good protection to pedestrians and the car scored maximum points in this area. The front edge of the bonnet was at best marginal in the protection offered to pedestrians. In most areas where a child's head might strike, the bonnet provided good protection but was predominantly poor in those areas likely to be struck by an adult's head.

Safety assist
Electronic stability control is standard equipment on the 208 and met Euro NCAP's requirements. A seatbelt reminder is standard for the driver and front passenger seats. A driver-set speed limitation device is also standard equipment.
