For enhanced safety, the front and rear seat shoulder belts of the Mazda 3 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 Volkswagen Jetta doesn’t offer pretensioners for its rear seat belts.
The Mazda 3 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 Jetta doesn’t offer knee airbags.
The Mazda 3 has standard Whiplash Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The Jetta doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The Mazda 3 Turbo Premium Plus has standard Smart Brake Support that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Jetta doesn’t offer backup collision prevention brakes.
The Mazda 3 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Jetta doesn’t offer all-wheel drive.
The Mazda 3’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Jetta.
The Mazda 3 Turbo Premium Plus has a standard 360-Degree Monitor to allow the driver to see objects all around the vehicle on a screen. The Jetta only offers a rear monitor.
The Mazda 3’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Jetta doesn’t offer a driver alert monitor.
Both the Mazda 3 and the Jetta have standard driver and passenger frontal airbags, front side-impact 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, rearview cameras, available blind spot warning systems and rear cross-path warning.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mazda 3 is safer than the Volkswagen Jetta:

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Mazda 3 Sedan is safer than the Jetta:

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Mazda 3, with its five-star roll-over rating, is 3% less likely to roll over than the Jetta, which received a four-star rating.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Mazda 3 the rating of “Top Safety Pick” for 2023, a rating granted to only 53 vehicles tested by the IIHS. The Jetta last would have qualified as a “Top Safety Pick” in 2017.
