The Civic was assessed earlier in July 2017.  Since then, Honda has introduced a modified side curtain airbag to lessen the impact of head bottoming out, seen in the previous assessment, of the head of 10 year child dummy in the side barrier test. Honda is working to further develop the side curtain airbag to improve performance in this area.

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.  Honda showed that a similar level of protection would be provided to occupants of different sizes and to those sat in different positions.  In the full-width rigid barrier test, protection of the driver was good or adequate.  However, for the rear passenger, dummy readings of chest compression indicated a weak level of protection for this part of the body.  For the side barrier and side pole tests, the Civic scored maximum points with good protection of all critical body areas.  Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision.  However, a geometric assessment of the rear seats indicated poor whiplash protection in those positions.  The standard-fit autonomous emergency braking system performed well in tests of its functionality at the low speeds typical of city driving at which many whiplash injuries are caused, with collisions avoided at all test speeds.

In the frontal offset test, dummy readings of neck tensions indicated marginal protection for both the 6 and the 10 year dummy.  In the 10 year dummy, chest deceleration also indicated weak protection of this part of the chest.  In the side barrier test, dummy injury values for the head of the 10 year dummy were reduced compared to the previous assessment (see General comments) but protection was still rated as weak.  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.  Since the Civic was last assessed, Honda has modified the position of the front passenger seatbelt buckle.  Now, all restraint types for which the Civic is designed could be installed and accommodated in the car.

The bonnet provided predominantly good or adequate protection to the head of a struck pedestrian but weak and poor results were recorded along the base of the windscreen and along the stiff windscreen pillars.  The protection provided by the bumper to pedestrians' legs was good at all test locations and maximum points were scored.  Protection of the pelvis was also good.  The autonomous emergency braking system can detect pedestrians as well as other vehicles.  In tests, the system performed well with impacts avoided or mitigated at all test speeds.

The autonomous emergency braking system performed well in the tests of its functionality at highways speeds, with collisions avoided or mitigated at all test speeds.  The Civic has a seatbelt reminder system for the front and rear seats.  Also standard is an intelligent speed limiter.  This indicates the local speed limit to the driver, who can then choose to set the limiter appropriately.  A lane keep assistance system alerts the driver when the car is drifting out of lane and gently steers the car away from the lane marking.
