Lap 12 at a Saturday club kart race. Two karts touch going into the hairpin, one rides up over the other’s rear wheel, and both spin into the grass. The drivers climb out, wave that they’re fine, and the race goes on. But the ten-year-old in the red kart is holding his side, and his dad is wondering whether that knock to the helmet was as harmless as it looked. Crashes still happen at every level, from rental karts and youth motocross to NASCAR, IndyCar, F1 and MotoGP. And even without a crash, the body takes a beating: g-forces load the neck, the seat presses the ribs and a hot cockpit inside a fire suit pushes body temperature up. This page covers the injuries that keep showing up, what lowers the risk and when to get checked.

General information, not medical advice. If you’re hurt, see a sports medicine doctor, physical therapist (PT) or certified athletic trainer (AT), and use the track’s medical team after any crash. For the bigger picture of the sport, start at our motorsports hub.

Crash injuries: what the data show

Safety rules work. A 2025 review of every Formula 1 driver from 1950 to 2023 (865 drivers) counted 264 injuries and 43 deaths over the sport’s history, and found clear drops over time in total injuries, deaths, fractures, head injuries and burns as safety rules evolved. A 2025 review in Current Sports Medicine Reports names the spine, shoulders and knees as common injury areas for car racers and calls helmets and head-and-neck support devices essential for lowering the risk of concussion and serious injury.

On two wheels the pattern is different, because riders fall off. The MotoGP medical team’s records of 9,092 crashes in MotoGP, Moto2 and Moto3 from 2013 to 2017 show that only about 1.3% caused a fracture, and riders typically returned after missing one to five weeks. The most common fractures needing surgery were in the upper limb, led by the collarbone (clavicle). An analysis of the 2024 MotoGP season found the same story in the serious cases: hand, wrist and collarbone fractures, from the instinct to put an arm out when you fall.

Collarbone and wrist fractures

The American Academy of Orthopaedic Surgeons (AAOS) explains that a broken collarbone usually comes from a direct blow to the shoulder or a fall on an outstretched arm. Signs: a sagging shoulder, pain that stops you lifting the arm, a grinding feeling, a bump or deformity, bruising and swelling. Significant pain or a visible deformity after a fall means a doctor and an X-ray, the same day.

Motocross injuries

Motocross is one of the highest-risk forms of racing. A 12-year study of European off-road competition (15,870 riders, 1,870 injuries) found that half of all fractures were in the arms and shoulders and 38% in the legs, and that knee ligament injuries made up the largest share of sprains and tears. The authors noted that even with better protective gear, knee sprains and wrist and collarbone fractures were still common. Indoor stadium racing (supercross-style) had a higher injury rate than outdoor motocross.

Kids race motocross too, from as young as 4 at some amateur events. A 10-year study of one week-long amateur championship in the US (286 hospital visits by children under 18) found that 25.5% of injured children were admitted to hospital, almost 10% needed surgery, about a third had injuries in more than one body system, and one teenager died. Families should take gear, bike size, track choice and supervision seriously. More on that on our youth motorsports page.

Karting rib injuries

Karts have no suspension, and the driver sits in a hard seat with ribs pressed against its edge through every corner. When the FIA (motorsport’s world governing body) introduced its karting body-protection standard, FIA 8870-2018, it said rib injuries were the most common injury in karting competition. The standard covers combined chest and rib protectors tested against impacts with the seat edge, steering wheel and steering column, and those protectors became mandatory in all FIA karting championships from 2021 and in all karting events on the FIA international calendar from 2022. Rib pain that builds over a race weekend, hurts when you breathe deeply or cough, or stays sore for days should be checked by a doctor: bruised or cracked ribs need time, not more laps.

Rental and recreational go-karts

Not every kart injury happens in a race. A 2026 study of US emergency-department data estimated about 34,561 visits for go-kart-related head, neck and spine injuries from 2004 to 2023. The median age was 15, nearly two-thirds of the injured were 18 or younger, and more than half of these injuries involved the head; concussion made up about 17%. Helmets, belts where fitted, and supervision matter just as much at a birthday party track as at a race.

Concussion: recognize it and get out of the car

A big impact can cause a concussion even with a top-rated helmet, and so can a hard jolt with no head contact at all. The CDC’s HEADS UP program is clear: if you think someone may have a concussion, remove them from activity. “When in doubt, sit them out.” They stay out for the rest of the day and until a health care provider clears them.

Signs to watch for (CDC): looking dazed or confused, slow answers, clumsiness, mood changes, vomiting, not remembering the crash. Symptoms drivers and riders report: headache, dizziness, nausea, blurry vision, sensitivity to light or noise, feeling foggy or slowed down. Call 911 or go to the emergency department for the CDC’s danger signs: one pupil larger than the other, a headache that gets worse and won’t go away, slurred speech, weakness or numbness, repeated vomiting, seizures, increasing confusion or agitation, or loss of consciousness.

Coming back is gradual. The 2022 Amsterdam international consensus statement on concussion in sport recommends only relative rest for the first 24–48 hours, then light activity, with each return step usually taking at least 24 hours, and the American Medical Society for Sports Medicine (AMSSM) says there is no same-day return after a diagnosed concussion. Final clearance comes from a licensed health care provider.

Neck loading from g-forces

In fast corners and under heavy braking, Formula 1 drivers feel forces upwards of 5 g, according to sports scientists writing in The Conversation: the head and helmet effectively weigh several times their normal weight, and the neck muscles have to hold them steady, corner after corner. A 2026 review in the British Journal of Sports Medicine, built on the published research plus interviews with three F1 performance coaches, found that F1 drivers are not especially exceptional in aerobic fitness or size, but they do have clearly stronger necks, and teams train for it routinely. Karts and other single-seaters load the neck too, on a smaller scale. A sore, stiff neck after a race weekend is common; pain that shoots into the arm, numbness, tingling or weakness is not, and needs a doctor. How drivers build neck strength safely is on our motorsports training page.

The other neck protection is the gear. NASCAR made head-and-neck restraints mandatory in October 2001, after a run of fatal crashes, and the FIA’s equipment rules make an FIA-approved frontal head restraint (the HANS type of device) mandatory for drivers in international events. Helmets for car racing carry standards such as the Snell Foundation’s SA rating; the new SA2025 standard took effect on October 1, 2025, with a stricter peak-g limit than SA2020. Replace a helmet after a significant impact.

Heat stress in cockpits and fire suits

A fire suit, gloves, balaclava and helmet are life-savers in a fire, but they also trap heat. Cockpit temperatures can exceed 50 °C (122 °F), the same sports scientists note. In a study of nine NASCAR Pro Series drivers in a hot race, core temperature rose from 38.0 to 38.5 °C and heart rates finished at 89% of age-predicted maximum. A study of male and female drivers found closed-cockpit cars produced higher core temperatures and physiological strain than open-cockpit cars. Researchers who measured drivers minute by minute warn that drivers heat up quickly and that longer events carry a real risk of serious heat illness.

The National Athletic Trainers’ Association (NATA) describes exertional heat stroke as a medical emergency: confusion, odd behavior or collapse plus a very high core temperature (above 40.5 °C). The rule is cool first, transport second, with cold-water immersion the most effective method. Dizziness, cramps, headache, nausea or unusual fatigue are early warning signs: get out of the suit and into shade and cooling. How to prevent it on race day (fluids, cooling systems, cold drinks) is on our race day page.

Gear many drivers use for prevention

No product prevents injuries on its own, and your rulebook decides what’s required. But karters commonly wear a rib protector such as the Alpinestars Youth Bionic Air Rib Protector or the OMP KK048 karting body protection (check whether your series requires an FIA 8870-2018 homologated model, and look for the label). For neck training at home, many drivers start with a simple Harbinger padded head harness and light weight, ideally under a coach’s eye.

When to see a sports medicine doctor, PT or athletic trainer

• Right away (emergency): any concussion danger sign, confusion or collapse in the heat, neck pain after a crash with numbness, tingling or weakness, a possible broken bone, trouble breathing or chest pain after a hit.
• Same day: any suspected concussion, collarbone or wrist pain after a fall, a knee that popped or swelled, rib pain that hurts with each breath.
• Soon: neck or back pain that keeps coming back after race weekends, rib soreness that lasts more than a few days, forearm or hand pain from gripping, a child who complains after every race.

Who does what: a sports medicine physician diagnoses and decides on scans; a physical therapist guides rehab and neck and shoulder strength; a certified athletic trainer often works with teams and series on prevention and first care. In pro racing, a dedicated medical team is part of every event; at club level, know where the track’s medical staff are before you go out. Getting back to full speed is easier with good habits after the race, covered on our motorsports recovery page. For how other sports handle the same issues, see our soccer injuries page.

Motorsports injuries: FAQs

What are the most common injuries in motorsports?

It depends on the vehicle. In karting, the FIA says rib injuries are the most common. In motorcycle racing and motocross, collarbone, wrist and hand fractures and knee ligament injuries lead the list. Car racers mostly deal with neck and back strain, heat stress and, in big crashes, head, spine and internal injuries.

Do karters need a rib protector?

In FIA karting championships, yes: an FIA 8870-2018 chest and rib protector has been mandatory since 2021, and in all karting events on the FIA international calendar since 2022. Club and national series set their own rules, but many karters wear one anyway because the ribs take a pounding against the seat.

Can a driver keep racing after a crash if they feel fine?

Not if a concussion is possible. The CDC says remove the athlete for the rest of the day until a health care provider clears them, and AMSSM says there is no same-day return after a concussion diagnosis. Symptoms can appear hours later, so a check by the track medical team is always worth it.

Why do race car drivers need strong necks?

Because cornering and braking forces multiply the effective weight of the head and helmet; F1 drivers feel upwards of 5 g. A 2026 review found stronger necks are the clearest physical trait that sets F1 drivers apart, and teams train it routinely.

How dangerous is motocross for kids?

It carries real risk. In a 10-year study of one US amateur championship, about a quarter of injured children were admitted to hospital and almost 10% needed surgery. Proper gear, a bike that fits, the right class for the child’s skill and adult supervision all matter; talk to your pediatrician as well.
