For enhanced safety, the front and rear seat shoulder belts of the Nissan Altima have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Toyota Prius doesn’t offer pretensioners for its rear seat belts.
The Nissan Altima has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Prius doesn’t offer a front passenger side knee airbag.
The Altima SL/SR VC-Turbo has a standard Intelligent Around View Monitor to allow the driver to see objects all around the vehicle on a screen. The Prius only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The Altima has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the Prius LE/XLE/Limited offers a blind spot warning system.
To help make backing out of a parking space safer, the Altima has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Only the Prius LE/XLE/Limited offers Rear Cross Traffic Alert.
Compared to metal, the Altima’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Toyota Prius has a metal gas tank.
Both the Altima and the Prius have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Altima, with its five-star roll-over rating, is 1.5% less likely to roll over than the Prius, which received a four-star rating.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, with its optional vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Altima its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS. The Prius last would have qualified as only a standard “Top Safety Pick” for 2019.
