average school bus weighs about 7 ton (14000) lbs if gross weight was over 26000 lbs
You can drive one with a Class C CDL with passenger and school bus endorsements, so long as the GVWR of the bus is 26,000 lbs. or less, but you cannot drive one without a CDL.
A school bus with a GVWR of 26,001 - 33,000 lbs. is, yes.
16000 lbs
The average school bus weighs about 7 ton (14000) lbs if gross weight was over 26000 lbs the driver would need a CDL not a bus drivers endorsement and most have air over hydraulic brakes
16.5 tons = 33,000 pounds 2000x16.5=33000
Your question doesn't make any sense. What is a "26,001 lbs. restriction", exactly? A Class B CDL covers commercial single vehicles with a GVW of 26,0001 lbs. and higher. You would need to get a school bus endorsement before driving a school bus, though.
I have 24 years experience in public transit. A forty foot transit bus has a GVWR of about 40,000 Lbs while the same make of bus in the twenty nine foot length is about 30,000 Lbs. The bottom line is that it varies a little by model and a lot by length. Even the "short" type school bus is likely to weigh in at 26,000.
A bus weighs roughly 12 to 14 tons. 13 Tons would make 29,120 pounds, 12 tons 26,880, and 14 would translate to 31,360 lbs. Translated, a bus would range from 29,000 to 32,000 lbs.
my 1992 vandura 6.2 diesel short bus weighs 10,000 lbs
14,000 - 16,000 lbs., depending on specifics.
There is no "school bus CDL". You either have a Class C or Class B CDL with a school bus endorsement. A Class C, you can drive any bus under 26,001 lbs. GVWR. If you get a hazmat endorsement, you can transport hazardous materials in any vehicle 26,000 lbs. GVWR or less. If you have a Class B, technically, you can drive any single vehicle with a Gross Vehicle Weight Rating of more than 26,000 lbs, but you're not going to get hired to drive a Class 8 with an unsynchronized manual transmission without any experience.
