School bus weight by type
School buses come in several size classes. The figures below show empty (curb) weight, since loaded weight depends on passenger count.
| Type (example) | Typical empty weight |
|---|---|
| Type A (small/van-based) | 4,500-6,000 kg (10,000-13,000 lbs) |
| Type B (mid-size) | 5,500-7,000 kg (12,000-15,400 lbs) |
| Type C (conventional) | 6,000-8,000 kg (13,000-17,600 lbs) |
| Type D (large transit-style) | 7,000-9,000 kg (15,400-19,800 lbs) |
| Fully loaded large bus | up to 16,330 kg (36,000 lbs) |
What affects school bus weight
- Bus class. Larger Type C and D buses weigh much more than small Type A models.
- Passenger load. A full load of students can add several thousand pounds.
- Body construction. Steel safety cages and reinforced floors add mass.
- Engine and fuel. Diesel engines and large fuel tanks add weight.
- Seating capacity. More seats means a longer, heavier body.
- Accessibility equipment. Wheelchair lifts and ramps add weight.
How school bus weight compares
An empty school bus at around 6,000 kg weighs roughly the same as a full-grown African elephant, or about four average cars.
