The phrase "safest vehicles" refers to cars, trucks or other modes of transportation that are equipped with advanced safety features and technology designed to minimize accidents and protect passengers in case of an accident. These vehicles often have a range of active and passive safety systems such as airbags, anti-lock brakes, electronic stability control, lane departure warning, blind spot detection, rearview cameras, and collision avoidance technologies that can help prevent or mitigate the severity of accidents on the road. The phrase is often used to describe vehicles with high safety ratings from organizations such as the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS).
