Do Motorcycles Have Seatbelts? (All Questions Answered!)

Last Updated on August 19, 2021 by Leepu Da Maxim

Generally, wearing a seat belt on a motorcycle can be a very dangerous thing to do in a traffic accident. A motorcycle is a much smaller vehicle compared to a car. So, there is not enough room here to cushion the impact of a crash. Also, a seat belt would leave the driver crushed or trapped with the vehicle. 

Reasons Why A Motorcycle Does Not Have Seat Belts

ReasonsDescription
Increased Danger
Incorporating a seat belt can keep the driver tied to the vehicle. This can cause the driver to be crushed by the bike itself.
Less Security
The safety elements seek to optimize the protection in a vehicle. A motorcycle seat belt decreases protection rather than increases it.
Small Vehicle
Unlike a car, a motorcycle does not have enough material for the seat belt to resist the kinetic energy of the impact. 
Inertia Speed
A seat belt can cause the driver to maintain the same inertial speed as the motorcycle. This could certainly lead to a greater number of fatalities.
Other Security ElementsA seat belt is not the only element of protection in a vehicle. Motorcycles are different vehicles than cars and have safety features such as helmets, gloves, and jackets. 

Why Are There No Seat Belts On Motorcycles?

Incorporating a seat belt into a motorcycle can increase the danger rather than protect the rider. That’s why a seat belt is not usually incorporated into these types of vehicles. Not only is the vehicle much smaller than a car, but the stability is also less. 

To understand the real reason for this, we must mention some concepts of physics. In this way, it will be much easier to understand why safety belts have not been incorporated into motorcycles on a massive scale. 

First of all, it is necessary to remember Newton’s first law to begin to understand this event. This first one tells you that a moving object can continue to move at the same speed. This happens until an unbalanced force acts on this object by changing the direction and speed. 

It is a natural tendency that allows objects to continue to behave as they were doing. All objects must deal with changes in their state of motion because there are a lot of unbalanced forces in the world. However, a moving object will always remain in the same motion without an unbalanced force.

In other words, this is usually known as the law of inertia. An unbalanced force may not be enough to break the inertia of an object. The law of inertia is most often experienced when drivers are on a road with a vehicle. Besides, this situation is one of the most common when there is a traffic accident and people are injured.

When objects continue to move during transportation, small or even fatal injuries can occur. The most common example is when a simple motorcycle crashes into any obstacle in its path, such as a wall. In this case, the unbalanced force of the wall is much more powerful than the speed provided by the movement of the object.

So, here the result is a motorcycle and a rider who abruptly decelerates and remains at rest. If a seat belt is incorporated in this case, then the driver is strapped into the motorcycle. Therefore, when the motorcycle hits the wall, the same thing happens to the driver.

Therefore, here the safety harness or seat belt will not be able to provide the proper protection for the driver. The driver is properly attached to the motorcycle. This allows both the driver and the motorcycle to share the same state of movement at all times. When this vehicle accelerates, then the driver also gains motion speed.

In turn, when the motorcycle decelerates the driver also loses speed. The same situation occurs with a constant speed that follows the motorcycle and is transferred to the driver. Beyond that, this situation is not what happens if the driver does not wear a seat belt. In particular, this is a common situation since motorcycles do not usually offer seat belts.

Both the motorcycle and the driver are two separate objects. The design of the motorcycle allows the driver to gain the speed that the vehicle produces. Here, the only thing that keeps the driver attached to the vehicle is the force of gravity. However, this force of gravity can easily be broken by an unbalanced force.

Therefore, when the motorcycle loses speed by hitting a wall this does not happen to the driver. Here simply the motorcycle and the driver do not share the same state of motion. Therefore, the rider will simply continue to ride at the same speed as before. Of course, what happens next is that the unbalanced force of the ground suddenly stops the driver. 

It is in this case that many motorcyclists are thrown off and lose contact with their vehicle. Of course, it is unlikely that a crash will cause the motorcycle to lose all speed and the rider to maintain the same speed as before the crash. However, something similar is what can naturally happen in most traffic accidents. 

In these cases, the driver becomes a projectile, as he continues to maintain his speed until the moment before the collision. It is precisely for this reason that motorcycle manufacturers have never included safety harnesses. Of course, safety is very scarce when it comes to a traffic accident with a motorcycle.

Vehicle manufacturers have the task of achieving the best safety qualities in the vehicle they manufacture. Thus, the driver of a motorcycle can optimize safety when not attached to the vehicle. In other words, this is the safest design for incorporating a seat belt. 

On the other hand, in a traffic accident involving a car things are very different. Specifically, here the safest place to be in a traffic accident is inside the car. The entire structure of this vehicle can serve as a support to withstand much of the impact of the traffic accident. Also, the seat belt allows you to be better secured inside the vehicle.

Therefore, the last place the driver wants to be in a traffic accident is next to the motorcycle. A car has four wheels and greater stability to prevent rollovers and loss of balance. Motorcycles logically have two wheels and much less stability.

This makes it much easier for these vehicles to roll over and for the driver to slide under or into the obstacles they hit. An example would be hitting a 2000 pound car. Here, the seat belt will simply keep you tied to the motorcycle, while you ride underneath this vehicle. 

So, the safety harness intended to protect the driver will allow you to be crushed by a 2000 pound vehicle. Besides, the chances of surviving this traffic accident are slim. That is why here the way to maximize the driver’s safety is to avoid him being tied to the motorcycle.

Following this last example, the motorcyclist could have better luck if he is thrown in the air outside and away from the vehicles. In this case, the driver will have to suffer a skid for a few seconds that may slow down the person’s inertial speed. 

In short, the lack of safety harnesses or seat belts is intended to maximize driver protection. Although it may seem somewhat contradictory, this feature can save some motorcyclists from suffering worse fates in a traffic accident. 

What Types Of Injuries Does A Seat Belt Produce?

When a seat belt is included in a car, then the driver’s protection is greatly increased. However, a normal motorcycle is not equipped with a seat belt because its operation can make any situation worse. Here, the driver will remain attached to the vehicle in a traffic accident.

Of course, this is dangerous, as the driver could be crushed or otherwise seriously injured. Beyond that, it is also necessary to consider that seat belts can produce different types of injuries in a car. So, this is another reason to avoid incorporating a seat belt into a motorcycle.

Most of the time injuries from this protective device are minor scrapes or bruises. More serious injuries are also usually related to collisions or serious traffic accidents. Internal injuries to the spinal cord or abdomen area due to lap belts. 

On the other hand, injuries to the sternum, neck, and shoulder can be caused by shoulder belts. Among the most serious injuries that can be caused by seat belts are the following:

1. Severe Bowel Injuries

2. Significant Spinal Injuries

3. Internal Bleeding That Is Not Immediately Detected

4. Considerable Damage To Internal Organs

5. Joint Dislocations

6. Fractures Of Different Types

If we consider that a motorcycle offers less protection to the rider, we can see that including a seat belt is a bad idea. In fact, in a traffic accident, these seat belt injuries can be more easily sustained on a motorcycle. That’s why it is convenient to choose to use the main protection elements of a motorcycle.

1. Helmet With The Right Size And Design For The Driver

2. Leather Jacket With Removable Armor Inside

3. Leather Pants That Can Resist Scratching With The Floor

4. Safety Boots With A Steel Toecap To Prevent Crushing Of The Fingers

5. Leather Gloves That Provide Warmth And Mobility To The Fingers

6. Glasses That Prevent Momentary Glare From The Sun Directly On The Driver
