The Arkana is structurally identical to the Renault Captur tested by Euro NCAP in 2019 and has the same safety equipment.  Based on data analysed by Euro NCAP, the same safety rating applies to both cars.

The passenger compartment remained stable in the frontal offset test. Dummy readings indicated good protection of the knees and femurs of the driver and passenger. Renault showed that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions. Protection was rated as good for all critical body areas for the passenger. In the full-width rigid barrier test, protection was good or adequate for all critical body areas, both for the driver and the rear passenger. In the side barrier impact, protection of all critical body areas was good and the car scored full points in this test. Even in the more severe side pole test, protection of the chest was adequate and that of other body regions was good. 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 standard-fit autonomous emergency braking (AEB) system performed well in tests of its functionality at the low speeds at which many whiplash injuries occur, with collisions avoided in most test scenarios.

In the frontal offset test, protection was good or adequate for all critical parts of the body, for the 6 and 10-year dummies. 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. The vehicle handbook says that the rear centre seat is not suitable for a universal child restraint, so the installation assessment was deemed a fail. Otherwise, all restraint types for which the car is designed could be properly installed and accommodated.

The protection provided by the bonnet to the head of a struck pedestrian was good or adequate at almost all test locations on the bonnet. The bumper provided good protection to pedestrians' legs but protection of the pelvis was generally weak or poor. The AEB system can detect vulnerable road users like pedestrians and cyclists, as well as other vehicles. In tests of its response to such road users, the system performed well, collisions against both being avoided or mitigated in all test scenarios.

A seatbelt reminder system is standard equipment for the front and rear seats. The AEB system performed adequately in tests of its response to other vehicles at highway speeds. A lane support system helps prevent inadvertent drifting out of lane. A speed assistance system uses a camera mapping to identify the local limit and the driver can choose to allow the car to adjust the speed limiter accordingly.
