Yes. Full-face helmets are the safest option for motorcycle riding because they protect the chin, jaw and face, the areas that crash studies show absorb a substantial share of impacts. Open-face and half helmets leave that zone completely unguarded. If maximum protection is the goal, a full-face or closed modular is the only rational choice.
The chin bar is not decoration. Crash research, most thoroughly documented in the European COST 327 study and in the work of researcher Dietmar Otte, consistently shows that a meaningful share of helmet impacts occur at the chin-bar region: the precise zone that open-face and half helmets simply leave exposed. No padding, no shell, no protection. If that region takes a hit, you feel all of it.
Our research desk went through the crash data, the ECE 22.06 test protocols and the engineering trade-offs to give you an honest answer: yes, full-face helmets are safer, and here is exactly why, where the gaps in the alternatives are, and what the honest trade-offs of wearing a full-face actually look like. We also cover where a modular slots in and where it falls short compared to a true full-face.
Why the chin bar is the key difference
In a motorcycle crash, the body's instinct is to lead with the face and chin as the rider pitches forward. The COST 327 project (a large European Commission crash study) and Dietmar Otte's injury research both found that the chin and face area accounts for a substantial share of all helmet impact zones, commonly discussed in the industry as roughly a third of recorded impacts. That figure is cited widely enough to be a baseline assumption in helmet design; it is why ECE 22.06 introduced specific chin-bar impact tests in its 2020 revision.
An open-face helmet covers the top, back and sides of the skull. A half helmet covers even less. Both leave the chin, jaw, teeth and lower face with zero hard protection. In a low-speed slide or a direct frontal impact, that gap is exactly where the pavement introduces itself.
Full-face vs modular: close, but not equal
A modular (flip-up) helmet is the closest thing to a full-face in terms of coverage. When the chin bar is locked down, it protects the same zones. That makes modulars a genuinely useful option (especially for riders who tour long distances or wear glasses) and modern high-end modulars earn ECE 22.06 certification in both open and closed positions, which is a meaningful improvement over older standards that only tested them one way.
The honest engineering caveat: a modular chin bar is a moving part held by a latch mechanism. A fixed full-face chin bar is structurally bonded into the shell. In a severe impact, a latch under extreme load is a potential weak point that a welded full-face shell does not have. The hinge and mechanism also add weight and complexity. For everyday riding, a quality ECE 22.06-certified modular is a defensible choice. For track days or maximum-protection commuting, a full-face remains the cleaner engineering solution.
- ECE 22.06 modulars are now tested both open and closed. That is a real safety step forward from 22.05.
- Latch integrity is the variable a fixed full-face eliminates entirely.
- Weight is typically 100-200g higher on modulars due to the hinge assembly.
- Convenience is real: raising the chin bar at a stop without removing the helmet is a genuine quality-of-life win for touring.
Full-face vs open-face: the protection gap is real
Open-face helmets cover the skull and offer good top-and-side impact protection. They are a popular choice for city commuters, cafe racer riders and anyone who values ventilation and a wide field of vision. The problem is structural, not cosmetic: the face and chin are exposed. Riders who crash in open-face helmets report road rash and injuries to the face and jaw at rates that full-face wearers simply do not experience in equivalent crashes.
There is also a debris and bug-strike consideration at higher speeds that is obvious once you have thought about it once. At 60 mph, a pebble becomes a projectile. A full-face visor stops it. An open face does not.
Open-face helmets are not reckless. Millions of riders use them safely and accept the trade-off knowingly. But the trade-off is real, and anyone making the choice deserves to make it with accurate information rather than a vague sense that "it'll be fine."
Full-face vs half-shell: the widest protection gap
Half-shell helmets (also called brain buckets or skull caps) cover only the top of the head. They offer the minimum possible legal coverage in jurisdictions that require helmets at all, and leave the face, chin, jaw, ears and much of the back of the head unprotected. DOT certification on a half helmet means the top portion met the DOT impact standard; it says nothing about the rest of the head.
The protection gap compared to a full-face is not a matter of degrees; it is a different category of device. In cruiser culture and certain agricultural or off-road settings, half helmets remain a legal and popular choice among riders who have consciously weighed the trade-off. For anyone whose primary goal is minimizing injury risk, the data does not support them as equivalent to a full-face. Riders who want the chin-bar protection of a full-face but still want a shape that suits a cruiser build can find well-matched options in our guide to full-face helmets for cruiser riders.
The honest trade-offs of wearing a full-face helmet
Full-face helmets are the safest option, and they come with real trade-offs that riders notice every day. Pretending otherwise does not serve anyone.
- Heat: a sealed chin bar means less airflow. In summer commuting or stop-start city traffic, a full-face gets warm. Look for helmets with aggressive chin vent systems if this is your primary environment.
- Weight: a quality full-face typically runs 1,400-1,600g. A half helmet can be under 700g. Over a long day, the weight difference shows up as neck fatigue.
- Visibility: a full-face visor gives a narrower horizontal field of view than open-face riding. This is mitigated by modern wide-vision shells, but it is a real geometric constraint.
- Claustrophobia and comfort: some riders genuinely cannot tolerate the enclosed feeling. That is a personal limit, not a failing, and it matters for consistent helmet use.
- Communication: having a conversation at a cafe or a tollbooth requires removing the helmet or raising a modular chin bar. Minor inconvenience for most; a deal-breaker for some.
None of these trade-offs change the safety data. They are reasons why a rider might rationally choose a different helmet for specific use cases, not reasons to believe a half helmet is equivalently protective.
What the safety standards actually test
Understanding the standards helps because "DOT certified" on a half helmet and "ECE 22.06 certified" on a full-face are not the same kind of claim.
- DOT (FMVSS 218, USA): self-certification. The manufacturer tests and declares conformance. Independent spot-checks happen, but no pre-sale lab verification is required. The DOT sticker on a helmet means the company says it passed.
- ECE 22.06 (Europe, updated 2020): independent test house certification required before sale. ECE 22.06 added rotational impact tests (IMPACT and MIPS-adjacent oblique tests), improved chin-bar standards, and introduced testing modulars in both open and closed positions. Considerably more rigorous than DOT.
- Snell M2025: third-party non-profit certification, often regarded as stricter than ECE on linear impact energy. Used widely in motorsport. Does not test rotational impact the way ECE 22.06 does.
- SHARP (UK): 1-5 star independent test ratings that layer on top of ECE certification. A useful comparator for buying decisions.
The takeaway for this question: ECE 22.06 now tests chin bars specifically and modulars in both positions. Buying a full-face or modular with ECE 22.06 certification gives you confidence the chin protection has actually been lab-tested, not just assumed.
Matching helmet type to your riding: a practical summary
For a full breakdown of all helmet types and how they differ in design and intended use, see our types of motorcycle helmet guide. The short version for this question is below.
The right helmet for any rider is the safest one they will actually wear consistently. A full-face that gets left at home because the rider finds it unbearable is not safer than an open-face that goes on every single ride. Comfort, fit and wearability matter, and they are also where budget matters: our cheap vs nice helmet breakdown covers what a higher price actually gets you in terms of comfort and long-ride usability. What the data does not support is the claim that different helmet types offer equivalent chin-and-face protection. They do not, and riders deserve to know that when making the choice.
Helmet type protection comparison
| Helmet type | Face protection | Chin protection | Relative safety |
|---|---|---|---|
| Full-face | Full visor coverage | Integrated chin bar, structurally bonded | Highest: covers all impact zones including chin |
| Modular (closed) | Full visor coverage | Latch-secured chin bar, ECE 22.06 tested open and closed | High: slightly below full-face due to latch mechanism |
| Modular (open) | None | None (chin bar raised) | Equivalent to open-face while open |
| Open-face / 3/4 | None | None | Good top-and-side protection; chin and face exposed |
| Half-shell | None | None | Minimum: covers top of head only |

Frequently Asked Questions
Are full-face helmets safer than open-face?
Yes. Full-face helmets cover the chin, jaw and face, the areas that crash research shows absorb a significant share of impacts in motorcycle accidents. Open-face helmets leave that entire zone unprotected. The protection difference is structural, not marginal.
Do I need a full-face helmet for city commuting?
You do not need one legally in most jurisdictions, but the safety data supports it. City commuting involves frequent low-speed crashes and hazards where chin and face protection is relevant. Many commuters choose open-face for comfort and visibility; that is a legitimate personal trade-off made with accurate information.
Is a modular helmet as safe as a full-face?
A quality ECE 22.06-certified modular with the chin bar locked down is close in protection to a full-face, but not identical. The latch mechanism that allows the chin bar to flip is an engineering variable a fixed full-face does not have. For everyday riding a certified modular is a strong choice; for track use, a full-face is the cleaner option.
What does ECE 22.06 test that older standards did not?
ECE 22.06, the current European standard updated in 2020, added rotational impact testing, tightened chin-bar impact requirements, and introduced mandatory testing of modular helmets in both open and closed positions. It is considerably more rigorous than the self-certification DOT standard used in the US.
Are half helmets dangerous?
They offer the minimum possible protection and leave the face, chin, jaw and ears fully exposed. They meet the legal minimum in many US states, and millions of riders use them, but the protection gap compared to a full-face is not a matter of degrees; it is a fundamentally different category of device. Riders who choose them should do so with a clear understanding of what they are and are not protecting.
