Type A School Buses are the smaller that typically weigh between 10,000 and 21,500 pounds. Type B School Buses usually weigh anywhere from 10,000 to 21,500 pounds. Type C School Buses usually weigh anywhere from 15,500 to 30,000 pounds.

Typical School Bus Weights

When you’re considering the weight of a school bus, it’s important to remember that there are different types and sizes of buses used for various purposes. School bus weights can be categorized into two main classes: Type A and Type C.

Type A School Buses are the smaller buses you often see transporting students to and from school events or serving as shuttle buses. Depending on the specific model and configuration, these buses typically weigh between 10,000 and 21,500 pounds.

Some factors that can influence the overall weight of a Type A bus include the number of seats, the type of chassis, and the additional features (such as wheelchair lifts).

Type C School Buses are the larger, standard yellow school buses that come to mind when you think of a school bus. Depending on their size and unique features, these buses can weigh anywhere from 15,500 to 30,000 pounds.

Much like with Type A buses, factors such as seats, chassis type, and added features can contribute to the overall weight of a Type C bus.

To give you a better idea of the varying weights within each type, here’s a breakdown of some examples:

  • Type A School Buses:

    • Cutaway Van Chassis: 10,000-14,000 pounds
    • Conventional Cab: 13,000-14,000 pounds
  • Type C School Buses:

    • Conventional Cab: 20,000-25,000 pounds
    • Flat-Front Engine (Transit-style): 22,000-26,000 pounds

Please note that these figures are general estimates, and the actual weight of a school bus will depend on the specific make, model, and features of each individual vehicle. When determining the weight of your bus, it’s always helpful to consult the owner’s manual or contact the manufacturer for accurate information.


How Much Does an Empty School Bus Weigh?

Type B buses are medium-sized and capable of carrying around 30-60 passengers. They have a gross vehicle weight rating (GVWR) of approximately 10,000 to 21,500 pounds. In general, the stripped weight for your average Type B bus is around 17,000 pounds.

Type C and D buses are your large, full-sized school buses. You might typically envision these when you think of a school bus. Type C and D buses can carry anywhere from 60 to 90 passengers and have a GVWR of 15,500 to 36,000 pounds. The empty weights of these buses range from 18,000 to 24,000 pounds.

Remember, these are rough estimates, and the actual weight of an empty school bus may vary slightly depending on factors such as additional equipment, extended lengths, or alternative fuel systems.

To find the specific weight of a particular bus, check the manufacturer’s specifications or look for the Vehicle Identification Number (VIN), which can usually be found in several locations, including the driver’s side dashboard and door frame.

How Much Does a Full School Bus Weigh?

When you think about a full school bus, it’s essential to consider the vehicle’s weight with all seats occupied by passengers. A standard school bus can hold approximately 65 to 72 passengers. Let’s break down the weight factors for a fully-loaded school bus to understand the total weight.

First, you want to know the weight of the bus when it’s empty (also known as its curb weight). When empty, a typical school bus usually weighs between 15,000 to 26,000 pounds (7.5 to 13 tons). Factors such as size, materials, and additional features contribute to the variation in weight.

Next, you should take into account the passengers’ weight. Assuming an average passenger weight of 150 pounds and a fully loaded bus with 72 passengers, your passengers would add around 10,800 pounds (5.4 tons) to your bus’s total weight.

Don’t forget that school buses also carry baggage, backpacks, and other personal belongings of the students. You can estimate an additional 15 to 20 pounds per passenger to factor in this weight. For 72 passengers, this would equate to 1,080 to 1,440 pounds (0.54 to 0.72 tons).

So, to calculate the total weight of a full school bus, you would need to add the empty bus weight, passenger weight, and baggage weight:

  • Empty school bus: 15,000 to 26,000 pounds (7.5 to 13 tons)
  • Passengers (72 individuals): 10,800 pounds (5.4 tons)
  • Baggage (for 72 passengers): 1,080 to 1,440 pounds (0.54 to 0.72 tons)

After adding all these factors, you’ll find that a full school bus weighs approximately 26,880 to 38,240 pounds (13.44 to 19.12 tons). Remember that these numbers are rough estimates and can vary depending on the size and bus type.

Factors Influencing Bus Weight

Bus Size

One of the factors that can influence a school bus’s weight is its size. Generally, larger buses weigh more than smaller ones. There are three main sizes of school buses: Type A, Type B, and Type C. Type A buses are the smallest, while Type C buses are the largest and can weigh up to 33,000 pounds. Make sure to consider the bus size when thinking about its weight.

Passenger Capacity

Another factor to consider is the passenger capacity of the bus. The more seats a bus has, the heavier it is due to the seats’ added weight and the passengers’ potential weight. For example, a school bus that accommodates 72 passengers will weigh more than a bus that can transport 30 passengers.

Construction Material

The weight of a school bus can also be influenced by the materials used in its construction. Buses can be made from materials like steel, aluminum, and fiberglass.

Each material has a different weight, so choosing a bus made from lighter materials can result in a lighter bus. However, remember that lower-weight materials might not be as sturdy or durable as heavier materials.

Added Features

Finally, added features on a school bus can also contribute to its overall weight. Some examples of added features include air conditioning systems, wheelchair lifts, storage compartments, and advanced safety features. While these features might make a bus more comfortable or safe, they can also result in a heavier bus.


Weight Categories of School Buses

As you explore the world of school buses, you’ll notice they come in various sizes and weights. Generally, school buses can be classified into three major weight categories based on their Gross Vehicle Weight Rating (GVWR). Each category has its unique attributes and is designed for specific purposes.

Type A school buses are the smallest and lightest of the three. These buses consist of a bus body built on a van chassis and have a GVWR of up to 14,500 pounds. Type A school buses can typically transport between 10 and 30 passengers. They are often used for special-needs students or routes with fewer students.

Type B school buses in the mid-size range can have a GVWR of 14,500 and 19,500 pounds. They are built on a chassis with a stripped-down frame, which means the body is built directly onto the frame. Type B school buses have a seating capacity of around 30 to 50 passengers. This makes them suitable for both urban and rural routes.

Finally, the largest category, Type C school buses, are designed with a GVWR of 19,500 to 33,000 pounds. Often called “conventional” school buses, they are built on a truck chassis with a separate, attachable bus body.

These buses can accommodate anywhere from 50 to 85 passengers. You’ll commonly see Type C school buses on regular school routes, as they provide ample space for larger groups of students.

School buses vary in weight based on their type and size. Type A buses are the lightest, followed by Type B and finally, Type C as the heaviest. As you consider your school transportation needs, factor in the number of passengers and the types of routes to determine which category of school bus best serves your requirements.

How Much Does a Type A Bus Weigh?

A Type A school bus (Type A1 & Type A2) typically weigh between 10,000 and 21,500 pounds. These smaller buses are perfect for transporting young kids or a small group of students. Their compact design often makes them a popular choice for many schools and organizations.

Type A school buses come in two different categories:

  • Type A1: Weighing between 10,000 and 14,500 pounds, these buses can carry up to 20 passengers. They are typically built on a van or truck chassis with a cutaway front section, making them ideal for more narrow roads and smaller routes.
  • Type A2: With a 14,500 to 21,500 pounds weight range, these buses can accommodate up to 30 passengers. They are similar in construction to Type A1 buses but often offer more extensive seating options and additional accessibility features.
