In Insurance Institute for Highway Safety (IIHS) crash-testing, the Yaris earned top 'good' ratings for frontal, side, and rear impact, but it was rated just 'acceptable' in the rollover-related roof strength test. The 2011 Toyota Yaris hasn't yet been tested under new, more rigorous crash tests and ratings standards introduced for this model year. Under the previous federal tests, the Yaris earned four-star results across the board.
The Toyota Yaris hasn't been particularly strong in safety, but Toyota has improved the package in the past couple of model years by making electronic stability control and anti-lock braking standard, as well as side and curtain airbags. To its credit, the Yaris is actually one of the few vehicles in its class of lowest-priced vehicles to offer the feature on every trim—even the base model.
