Wondering how much does a school bus weigh? It’s a very interesting question and we will provide you with the most accurate answer.
Buses are important to the service provided by the school for picking up the students from their homes in the morning and dropping them off after school. Every school has many buses that are required for carrying the kids to and fro from school to home and vice versa.
Traveling in school buses gives security and safety to the kids as they do not have to travel by public transport and the hassle of the parents picking up the kids in the middle of their busy schedule is also compensated.
Now we shall discuss the size and the capacity of each of the school buses and determine their weight in this article.
Have you ever wondered what a school bus weighs? Well, if you haven’t then in this article we will help you to get an idea of its size and weight!
How Much Does A School Bus Weigh?
Weight of an Empty School Bus = 10,000 to 25,000 pounds (5 tons to 12.5 tons)
Weight of a Full School Bus = 14,500 to 36,000 pounds (7.25 tons to 18 tons)
On average, we can say that a school bus weighs around 10,000 to 25,000 pounds when empty and 14,500 to 36,000 pounds when full.
However, this is only a general observation as there are many sizes and lengths of the buses and thus we shall further study in detail the size of the buses and the particular weight of each.
What is the Average Weight of a Type A Bus?
A Type-A bus weighs around the least among the rest when compared with other buses. These are the smallest in size and can only carry ten passengers at a time. There are two types of type A buses and we can determine their weights differently. Now, the Type A-1 bus weighs around 10,000 pounds when it’s empty.
At full capacity, which is around 10 passengers, it weighs around 14,500 pounds. Hence we have determined the weight of the first category, that is Type A-1 bus’s weight when empty and full.
The Type A-2 buses are also known for carrying less number of passengers however not as less as type A-1. When the bus is empty, the Type A-2 bus weighs the same as the Type A-1 bus at around 10,000 pounds.
Now if you see the weight of the type A-2 bus when filled up to its full capacity, it shall be noted that the weight of the bus will be different and much more than A-1 since type A-2 has the capacity of twenty-four passengers. It weighs around 21,500 pounds when fully occupied.
On rage, we can say that the weight of a type A bus is seven to eleven tons.

What is the Average Weight of a Type B Bus?
Moving on to the next kind of bus, here we have the type B bus. This bus does not look like an ordinary bus but is more like a truck with an attached bus behind it. Hence this bus is also called the half bus. The size of the bus is similar to that of the Type A-2 buses. Since these two types of buses are similar in size the capacity of the type B bus is also around 10 to 24.
When it’s empty, the Type B bus weighs around 10,000 pounds.
However when the bus is filled to its entire capacity, the Type B bus weighs similarly to a Type A-2 bus at 21,500 pounds.
What is the Average Weight of a Type C Bus?
When we talk about school buses, this is the bus that is most commonly spotted on the road. The buses have a long face and a longer back to accommodate as many as 72 passengers at a time. These buses are the traditional school buses that are observed when we discuss size in school buses.
It shall be noted that when a Type C bus is empty, it weighs about the same as when a Type A or B bus is full.
However, the difference in weight arises when we are discussing the size of when it is full and what weight it shows.
It can weigh anywhere from 15,500 pounds to 21,500 pounds when it’s empty. But when the Type C bus is full its weight ranges from 25,000 pounds to 30,000 pounds. It shall also be noted that if more passengers are loaded in the bus than its usual capacity then the type C bus can weigh more. On average, we can state that the approximate weight of the type C bus ranges from 12 to 15 tons.
What is the Average Weight of a Type D Bus?
The appearance of a type D bus is almost the same as the type C bus and the weight of the buses is also more or less similar. These buses are of the size of type C but they have a flat front instead of the long one like type C.
The average length of a type D school bus is 45 feet and it is very popular in the cities. They can carry up to 72 passengers just like type C buses.
That means that Type D buses weigh around 15,500 to 21,500 pounds when empty and 25,000 to 30,000 pounds when full.
Hence we have a calculation to determine and compare the weight of different types of school buses.
How do you determine the weight of the bus?
If you are planning to weigh each of the parts of the bus then it is a very difficult process. However, if you wish to calculate the weight of the bus then the best technique is to measure its weight empty first, that is, devoid of passengers.
Then determining the weight of the passengers exclusively may be a difficult process since everyone has a different weight and it will continuously vary. Hence the average weight of each child is approximately taken as 100 pounds.
Hence you just need to multiply the weight of each kid by the number of kids on the bus to determine the total weight of the passengers. Then you simply need to add the total weight of the passengers with the original weight of the bus to obtain the final weight.
If you wish to have more accuracy, then the process is a bit more complex. Here you have to note that the weight of each kid is unique. Some who are in kindergarten are less weighted than the ones in class twelve. Also, a healthier kid of similar age will weigh more than a thinner one. Hence if you wish to maintain accuracy then you have to individually weigh each of the kids and then add all the values with the original weight of the empty bus.
What Factors Determine the Weight of a Bus?
1) Length of the bus
The length of a bus is a major factor that determines its weight. Type A buses are the shortest in length and hence they weigh the least. In the case of the Type C and Type D buses, the length of these vehicles is more and hence they were also more.
2) Seats on the bus
The number of seats in a bus also determines the weight of the bus. If a bus has 30 seats then its weight will certainly be less than a bus that has 35 seats. If the seats are smaller the weight recorded will be less than seats that are larger in length. These seats are made with steel rods and provided with cushions and hence each of them has significant weight to add to the overall weight of the buses. If the bus is constructed for special kids and the physically disabled then again the arrangement and construction of the seats may vary as a result, and the weight will also change considerably.
3) Construction material of the buses
The material with which a bus is designed also plays a significant role in determining the size of the bus and its weight. These buses are mainly constructed with a combination of steel, aluminum, and plastic. The tools and parts made from plastic are lighter than steel and thus they are overall less weighted. Aluminum is also lighter than steel and thus a type D bus made with aluminum is lighter than that of type D steel buses.
the number of passengers that are traveling in a bus is also largely influential in determining the weight of the bus. If a bus carries 60 passengers and another bus carries 30 passengers then the former will certainly weigh more than the latter.
Now again, the weight of a bus at the beginning of the journey with more passengers will be heavier than a bus at the end of the journey when it has dropped off the children. Hence, we can say that if a bus is carrying band kids then the bus will weigh more because band kids will carry instruments like guitars, etc.
5) Gas tanks
Gas tanks are established in a bus depending upon the journey it will cover. If the road is smooth and the distance is less, then the gas tanks set up are relatively lesser in weight than in buses in rural areas where the vehicle has to cover rough roads. This is thus another factor that helps to determine the weight of the vehicle and a crucial factor that must be taken into consideration when determining the weight of a school bus.

When was the First School Bus Made?
The first school bus was a wagon that came into existence in 1892 and it had a sitting capacity of 20 students. The seats were made of wooden planks. Wayne Works was the company that showed expertise in building transport for the kids.
Ohio commissioned the company to construct the first school bus to trod the road. Instead of being horse-driven, the structure of the bises changed rapidly between the 1900s and 1930s. The buses were soon the engine runner vehicles. By 1939, the modern-day buses had come into existence.
