Front impact
The passenger compartment remained stable during the impact. The driver's knees were well protected by an airbag mounted in the lower dashboard. Peugeot showed that the airbag would also protect occupants who were larger or smaller than the dummy used in the test, and those sat in different seating positions. The passenger was well restrained and his knees did not get close to the dashboard.

Side impact
The 308 scored maximum points in the side impact and pole tests.

Child occupant
The passenger airbag can be disabled to allow a rearward facing child restraint to be used in that seating position. However, information provided to the driver regarding the status of the airbag is not clear. The presence of ISOFIX anchorages in the front passenger seat and the rear outboard seats was not clearly marked.

Pedestrian
The bumper scored maximum points for its protection of pedestrians' legs. Also, the protection offered by the bonnet to the head of a struck child was predominantly fair. However, protection of adults' heads was mostly poor.
