Adult occupant
The passenger compartment remained stable in the frontal impact. Dummy readings indicated only marginal protection for the driver's chest, knees and lower legs. The Isuzu D-max scored maximum points for the protection it provided in the side barrier test. The front seat and head restraint provided good protection against whiplash injuries in a rear-end collision.

Child occupant
Based on dummy readings in the frontal and side impact tests, the 18 month old child offered only adequate protection to the neck and chest. However, poor protection was offered to the chest of the 3 year old child. The passenger airbag could not be deactivated to allow for placement of a rearward facing child restraint on the front passenger seat. Permanently attached labels on the sun visor clearly warn of the dangers of using a rearward facing child seat in that position without first disabling the airbag.

Pedestrian
In those areas likely to be struck by a pedestrian's lower leg, the protection was good. The front edge of the bonnet offered poor protection, which is where a pedestrian's upper leg would contact. In most areas likely to be struck by the head of a child and an adult, the protection was mostly marginal and poor.

Safety assist
Electronic stability control is standard and met Euro NCAP's requirements. There is a seatbelt reminder system for the driver and passenger, but not for the rear seats. The Isuzu D-max is not available with a speed limitation device.
