Bleeding control kits and Stop the Bleed training: what is inside and when to act
Choose a reliable kit, learn how tourniquets work and keep your skills ready
Safety Behind the Wheel Foundation built this guide from National Highway Traffic Safety Administration (NHTSA) data, the U.S. Department of Homeland Security’s Stop the Bleed campaign, American Red Cross course information, federal workplace first aid rules and published trauma research. Every source is listed at the end.
Why bleeding control belongs in your plan for a car accident
In 2024, 39,254 people died in traffic crashes on roads in the United States, and about 2.42 million more were injured [1]. Some collision injuries cause heavy bleeding from an arm, a leg or a deep cut.
Bleeding like that can kill fast. Heavy bleeding can kill a person in as little as five minutes [2]. However quickly responders come, the people already at the scene will be there first [2].
Help can take a while. A national study of 2015 emergency calls found the median wait for the first ambulance was 7 minutes [3]. In rural areas, it was 13 minutes [3]. A trained bystander with the right tools can fill that gap.
It also helps to know what a kit cannot do. One study reviewed 512 people in a large urban county who died of injuries in 2011 before reaching a hospital [4]. Bleeding was the second most common cause of death, at 34% [4]. Reviewers judged that 29% of the deaths might have been survivable, mostly ones involving bleeding or chest injuries [4]. A kit helps with bleeding you can see and press on. It cannot stop bleeding inside the chest or belly, so calling 911 early always comes first.
Our guide to post crash care covers the first minutes after a car accident. This guide goes deeper on one piece: the kit, the tourniquet inside it and the training that makes both useful.
What a bleeding control kit is, and what it is not
A regular first aid kit is built for small problems like scrapes and minor burns. A bleeding control kit is built for the rare moment when someone could bleed to death. It is small, quick to open and holds only what that job needs.
A few terms first. A tourniquet is a wide strap that goes around an arm or leg, above the wound. When you tighten it, it squeezes the blood vessels shut. Most use a windlass, a short rod you twist to tighten the strap and then lock in place. Wound packing means pushing gauze firmly into a deep wound, then pressing on top. Hemostatic gauze is gauze treated with a substance that helps blood clot.

What a bleeding control kit holds
| Item | What it is for | What to look for |
|---|---|---|
| Tourniquet | Stops heavy bleeding from an arm or leg | Purpose built, with a windlass and a lock |
| Packing gauze (plain or hemostatic) | Fills deep wounds so pressure reaches the bleeding | Sealed, compressed, within its date |
| Pressure bandage | Holds steady pressure on a wound | Built in pressure pad or bar |
| Medical gloves | Protects you from blood | Several pairs, nonlatex |
| Trauma shears | Cuts clothing to find the wound | Blunt tip so you do not cut the skin |
| Permanent marker | Records the time a tourniquet went on | Writes on skin or tape |
| Instruction card | Reminds you of steps under stress | Short, picture based steps |
Some professional kits add items such as chest seals. Use those only if your training covered them.
Who carries a kit, and why
Many groups that work in or near traffic carry these kits:
- Fire departments and ambulance crews.
- Towing and roadside recovery operators, who may reach a wreck alongside responders.
- Road agency and work zone crews, who work feet from moving traffic.
- Fleet drivers and trained workplace responders.
- Families and everyday drivers who have taken a bleeding control course.
Employers also have a federal baseline. When no clinic or hospital is close to the workplace, at least one person must be trained in first aid [5]. Adequate first aid supplies must also be easy to reach [5]. The rule points employers to a national first aid kit standard, ANSI Z308.1, and asks them to add supplies that fit their hazards [5]. For crews who work on the road, a bleeding control kit can fill that gap.
When to act: spotting life threatening bleeding
Most cuts bleed slowly and stop with light pressure. Courses teach you to recognize the bleeding that can kill [6]. Act fast if you see any of these signs:
- Blood that spurts or pulses out of a wound.
- Blood that pools on the ground or seat and keeps spreading.
- Clothing or bandages that keep soaking through.
- An arm or leg that is partly or fully cut off.
- Heavy bleeding in a person who is confused, pale or passing out.
If you are unsure, treat it as serious. Pressing hard on a minor wound does far less harm than waiting on a severe one.
Trained responders follow an order like this one. It reflects the core of national courses: recognize the emergency, press directly on the wound and use a tourniquet when needed [6].
- Check for danger. Traffic, fire and leaking fuel come first.
- Call 911, or point at one person and tell them to call. Use the speaker.
- Put on gloves if you have them. Do not let a missing glove stop you.
- Cut or open clothing so you can see where the blood is coming from.
- Press hard, right on the wound, with gauze or cloth. Use both hands and your body weight.
- If the wound is deep and you are trained, pack gauze into it and keep pressing.
- If the wound is on an arm or leg and pressure is not working, apply a tourniquet.
- Stay with the person, keep them warm and tell responders what you did.
Tourniquets: how they work and what the evidence shows
Many people worry that a tourniquet will cost someone a limb. Civilian research is reassuring.
One study looked at 1,026 patients with major blood vessel injuries to the arms or legs [7]. They were treated at 11 top level trauma centers in Texas from 2011 to 2016 [7]. After adjusting for other factors, a tourniquet placed before the hospital was linked to about a sixfold drop in deaths [7]. Delayed amputation rates were the same, about 1.1%, in both groups [7].
A later study followed injured limbs at 29 trauma centers from 2015 to 2020 [8]. Tourniquets controlled bleeding in 87.7% of limbs [8]. Fewer of them were in shock when they reached the hospital: 13.0%, compared with 17.4% without one [8]. Limb problems were not significantly more common [8].
Tourniquets are not harmless, though. A 2025 review found that leaving one on for a long time can cause nerve damage and other problems [9]. Nerve injury was the most common [9]. That is why the time matters, and why the hospital team decides when it comes off.
When you use one, keep these basics in mind:
- Place it on the limb above the wound, on the side closer to the body. Follow the placement rules from your course and the device instructions.
- Pull the strap tight before you twist. A loose strap can let blood keep flowing.
- Twist until the bleeding stops, then lock the windlass.
- Expect it to hurt. Pain does not mean you did it wrong.
- Ask your instructor what to do if one tourniquet does not stop the bleeding.
- Write the time on the tourniquet or the skin, and tell responders.
- Do not loosen it to “check.” In one study, tourniquets placed before the hospital stayed on for about 77 minutes on average [7].
Choosing a kit: reputable equipment only
The tourniquet is the item to get right. Other items are easier to replace or improvise.
Improvised tourniquets are a poor backup. In a lab test, a T shirt tied around a training leg failed to stop bleeding in 99% of tries without a windlass [10]. Even with a stick used as a windlass, it failed 32% of the time [10]. Belts and cords are better than nothing, but they are not a plan.
Look alike products are another risk. Medical authors warn that counterfeit tourniquets are widely available and may lack quality control [11]. Their 2024 case report described a soldier who died in 2022 after the windlass on a copied tourniquet broke during transport [11]. That was a war zone, but the lesson holds anywhere: a tourniquet must hold under strain.
Buy from channels that can show where the product came from:
- Professional emergency equipment suppliers that sell to fire and EMS agencies.
- Authorized dealers listed by the tourniquet’s maker.
- Bleeding control training organizations, or your employer’s safety supply vendor.
Training: the kit is only half of the answer
A tourniquet in untrained hands often fails. In one study, stadium workers tried to apply a tourniquet in a simulation [12]. Only 14.4% of those with no prior training did it correctly [12]. Even among those with past first aid and bleeding control training, only 35.8%, or about one in three, got it right [12].
Recent practice helps. In a randomized study, laypeople who took brief online training a few weeks ahead, plus quick instructions at the scene, applied a tourniquet correctly 75% of the time [13]. Those with only the quick instructions succeeded 50% of the time [13].
Skills also fade. In another study, everyone applied a tourniquet correctly at the end of class [14]. Six months later, 39% could not apply it successfully, and 26% could not control the simulated bleeding [14]. The author called for refresher practice no later than six months after class [14]. Safety Behind the Wheel Foundation encourages kit owners to follow that same refresher schedule.
The Stop the Bleed campaign, promoted by the Department of Homeland Security, lists four course options [2]. They include a bleeding control basics course from a national surgeons’ group and a federal course suite called You Are the Help Until Help Arrives [2]. They also include a first care provider course and the American Red Cross First Aid for Severe Trauma course [2]. That Red Cross course runs about 135 minutes in person, or 90 minutes online plus 45 minutes of hands on class [6]. An online only version gives a completion certificate, not a certification [6].

Bleeding control course formats compared
| Course format | Good for | Watch out for |
|---|---|---|
| In person class | First time learners and work crews | Must schedule a time and place |
| Blended (online plus skills session) | Busy adults who want hands on practice | Do not skip the skills session |
| Online only | A refresher between classes | No one checks your technique |
One point matters most: practice with your hands, not just your eyes. Put a training tourniquet on your own arm and a partner’s leg. Try it while sitting in a car seat, too.
Where to keep the kit
A kit only helps if you can reach it in seconds.
- In a car, keep it within reach of the front seats, such as a seat back pocket or under seat mount, not under cargo in the trunk.
- Secure it so it does not fly forward in a hard stop, and tell regular passengers where it is.
- Put one kit in every work truck, tow vehicle and crew vehicle, in the same spot each time.
- At fixed sites, mount kits with clear signs where people look for emergency gear. One option is next to an automated external defibrillator (AED), which a companion guide covers.
Keep it ready: inspection and maintenance
Bleeding control supplies sit unused for months, then must work the first time. A short routine keeps them ready.
- Every month, open the kit and confirm every item is there.
- Check expiration dates on gauze, dressings and gloves. Replace anything close to its date.
- Inspect the tourniquet strap, windlass and lock for cracks, fraying or sun damage.
- Practice with a separate tourniquet marked as a trainer, so a worn unit never ends up in a live kit.
- Check the maker’s storage temperature range. Parked cars get very hot and very cold.
- Restock right after any use, and keep your next refresher date on the calendar.
Common mistakes to avoid
- Buying a kit and skipping training. Book a class the same week you buy the kit.
- Waiting too long. Press hard first, then decide on next steps.
- A loose or loosened tourniquet. Snug the strap, twist until bleeding stops and leave it on.
- Forgetting the time. Write it down for the hospital team.
- A counterfeit or worn device. Buy from trusted channels and keep trainers out of live kits.
- Ignoring your own safety. Check for traffic, fire and fuel before you kneel down.
Frequently asked questions
Will a tourniquet cause someone to lose a limb?
That fear is common, but civilian research is reassuring. In one large study, delayed amputation rates were about the same with or without a tourniquet [7]. Another found that limb problems were not significantly more common when tourniquets were used [8]. Very long tourniquet times can injure nerves, so the hospital team decides when to remove it [9]. Your job is to stop the bleeding and note the time.
Can I use a tourniquet on a child?
Children can bleed heavily too. Read the device instructions for any limits on limb size before you need it. If a tourniquet will not tighten enough on a small arm or leg, use firm direct pressure and wound packing instead. Ask your instructor to cover children and small adults in class. In a real emergency, call 911 right away and keep pressing until help arrives.
How often should I take a refresher course?
Skills fade faster than most people expect. One study found that six months after a class, nearly four in ten people could not apply a tourniquet correctly [14]. The author recommended refreshers within six months [14]. A good habit is a short hands on practice every few months, plus a full refresher on the schedule your course provider advises.
What if I do not have a tourniquet when someone is bleeding?
Call 911 first. Then press hard on the wound with the cleanest cloth you have, using both hands and your body weight. Keep pressing until responders take over. An improvised strap can be tried on a limb, but in lab tests improvised tourniquets often failed, even with a stick to tighten them [10]. Steady, hard pressure is the most reliable option without proper equipment.
Should I help a stranger after a crash?
Many people want to help but worry about doing something wrong. A bleeding control course builds the skill and confidence to act. Bystanders are almost always on the scene before professional responders [2]. If you are unsure about legal protections where you live, ask your course instructor or your state’s emergency medical services office.
The bottom line
Recommendation from Safety Behind the Wheel Foundation
Safety Behind the Wheel Foundation urges every driver who carries a bleeding control kit to take a hands on course and keep the kit within reach. Severe bleeding is one of the few crash injuries a bystander can treat in the first minutes. A small kit with a reputable tourniquet, packing gauze, a pressure bandage, gloves and shears gives you the tools. Training gives you the skill, and refreshers keep it sharp.
Buy from trusted suppliers, keep the kit within reach and check it monthly. Most of all, take a course. You may never need it, but if you do, those minutes will matter.
