The passenger compartment of the Yaris remained stable in the frontal offset test.  Dummy readings indicated good protection of the knees and femurs of the driver and passenger.  However, structures in the dashboard were thought to present a risk to occupants of different sizes and to those sat in different positions, and protection of this body region was rated as marginal.  Protection of the driver's chest was also rated as marginal, based on dummy readings of chest compression.  In the full-width rigid barrier test, protection of the driver was good or adequate.  However, the pelvis of the rear passenger dummy slipped under the lap section of the seatbelt and protection of the pelvis was rated as poor.  In addition, the head moved further forward in the impact than recommended and its protection was rated as marginal even though dummy injury values were not excessive.  In the side barrier test, protection of all critical body areas was good and the Yaris scored maximum points.  However, in the more severe side pole test, dummy readings indicated marginal protection of the chest and abdomen.  Tests on the front seats and head restraints demonstrated good protection against whiplash injury in the event of a rear-end collision.  A geometric assessment of the rear seats also indicated good whiplash protection.  The Yaris has, as standard, an autonomous emergency braking system.  In tests of its functionality at the low speeds at which many whiplash injuries occur, the system demonstrated good performance, with collisions avoided or mitigated at all test speeds.

In the frontal offset test, protection of both child dummies was good or adequate.  In the side barrier test, the curtain airbag did not cover the area needed to provide protection for the head of the 10 year dummy, sat on the struck side.  The head contacted the interior trim and recorded deceleration which demonstrated marginal protection for this critical body area.  Protection of other critical body areas was good for both child 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.  Installation of the rearward-facing Group 0+ universal restraint in the rear centre seating position was not possible owing to insufficient length of webbing to pass around the shell and buckle the belt.  Otherwise, restraints could be properly installed and accommodated in the car.

The protection provided to the head of a struck pedestrian was predominantly good or adequate, with poor results recorded on the stiff windscreen pillars.  The protection offered to pedestrians' legs was good in all areas tested while that offered to the pelvis was good in some areas and weak in others.  The autonomous emergency braking system detects other vehicles but cannot detect vulnerable road users such as pedestrians or cyclists.

The Yaris has a seatbelt reminder for the front and rear seats.  The standard-fit autonomous emergency braking system performed well in tests at highway speeds, with collisions avoided or mitigated in most scenarios.  A lane departure warning system is also standard equipment on the Yaris.
