The passenger compartment of the 01 remained stable in the frontal offset test. Protection of all critical body areas was good or adequate for both the driver and passenger dummies. Protection of the knees and femurs was good and Lynk & Co. showed that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions. Analysis of the deceleration of the impact trolley during the impact, and of the deformable barrier after it, indicated that the 01 would be a benign impact partner in a frontal collision. In the full-width rigid barrier test, protection of all critical body areas was good or adequate. In both the side barrier test and the more severe side pole impact, the Lynk & Co. 01 provided good protection to all critical body areas and scored maximum points in this part of the assessment. Tests showed that the excursion (the extent to which an occupant is thrown to the other side of the car in a far-side impact) was adequately controlled, and that the centre airbag, designed to mitigate occupant to occupant injuries in such impacts, performed well. Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision. A geometric assessment of the rear seats also indicated good whiplash protection.  The Lynk & Co 01 is equipped with a post-impact braking system, designed to prevent secondary collisions, and with an advanced eCall system which automatically alerts the emergency services in the event of a serious accident.

In the frontal impact, protection of all critical body areas of both the 6 year and 10 year dummy was good, apart from the neck of the 10 year dummy, protection of which was adequate. In the side barrier test, the Lynk & Co. 01 provided good protection to all critical body areas and scored maximum points. The front passenger airbag can be disabled to allow a rearward facing child restraint to be used in that seating position. Clear information is provided to the driver regarding the status of the airbag and the system was rewarded. All of the restraint types for which the 01 is designed could be properly installed and accommodated.

The bonnet provided predominantly good or adequate protection to the head of a struck pedestrian, with some poor results at the base of the stiff windscreen pillars. The bumper provided good protection to pedestrians' legs at all points tested by Euro NCAP. Protection of the pelvis was more mixed, with some test points showing good protection and other performing poorly. The 01 has an autonomous emergency braking (AEB) system which can detect vulnerable road users like pedestrians and cyclists as well as other vehicles. In Euro NCAP's tests of it reaction to cyclists, the system performed well, with collisions avoided in most scenarios tested. The system's reaction to pedestrians was rated as adequate. The 01 does not have a system to help avoid accidents where the car reverses into pedestrians.

The Lynk & Co. 01 has a seatbelt reminder system, including occupant detection in all seating positions, as standard. It is also equipped with a system which monitors the driver's state of alertness using steering inputs which can provide indications of fatigued or impaired driving. A lane support system gently corrects the car's path if it is veering out of lane, and also intervenes in some more critical situations to stop the car from leaving the road. The speed assistance system recognises the local speed limits, allowing the driver to set the limiter appropriately. The AEB system worked adequately in Euro NCAP's tests, with collisions with other vehicles avoided in several test scenarios.
