Since the 2009 Smart Fortwo is built by Mercedes-Benz, ample occupant protection would be expected, and the Smart delivers. Standard safety equipment includes side airbags, antilock brakes (front discs and rear drums), stability control and traction control. Despite its tiny size, the Smart car has performed well in crash testing. In government crash tests, the Smart was awarded four out of five stars for frontal crash protection of the driver and three stars for passenger protection. In side impacts, the Smart was awarded a perfect five out of five stars. The Insurance Institute for Highway Safety awarded the Smart its highest rating of Good for both frontal and side impact protection.
