Just not interested in going off topic with the peanut gallery. And I didn't misread anything.
There are two agreements you will sign... a contract to lease the truck, and an operating agreement with a carrier. Usually you will find clauses in each contract specifying costs that you or the carrier are responsible for.
The lease agreement is with the leasing company which can be with a totally separate outfit like Lone Mountain Leasing, but many times is a captive company associated with but legally separate from the carrier. Make sure you understand the cost structure of the lease. For example from what
@Mike posted the truck payment is just that, and insurance is separate. With Prime and Success Leasing, you will be quoted a truck payment that includes insurance.
There will be other costs as well... sometimes these are paid by the carrier or leasing company... sometimes you. It does make a difference. For example, JCT makes a big deal out of claiming they pay for reefer fuel... at Prime, the carrier pays to fill the tank once, and then its on your dime. Guess what? Its not a major issue unless they're using old, ratty reefer trailers. How you pay for fuel is a big deal. Are you constrained to one truck stop chain, or do they have a big network? Do you pay IFTA tax or does the carrier? What kind of discount comes with your fuel card? These are things you need to know about, so understanding the contract is really important.
The other contract is leasing your truck on with the carrier... and this explains your operating relationship with them. If you need to lease a trailer, that would be explained here. The way you get your freight, restrictions on co-drivers, the way you're paid, revenue splits are all contained in here.
Something you really do have to understand is how these agreements can be terminated by either you or the carrier. Generally, these agreements are written in a way that the carrier can pull the plug at any time. If you terminate the lease there can be financial repercussions. For example, at CR England, you are responsible for the truck payments until they get around to leasing it to someone else. Generally you will be responsible for damage, and an escrow will be established to provide funding for repairs if you are in the hole when you depart. Its important that you understand the consequences of terminating the lease on your part before you sign the thing.
Maintenance and tire financing is another area you need to explore up front. How is it funded? Will there be a warranty, and when does it run out? Who calls the shots on what will be repaired, and to what degree will it be repaired? Do you have a choice between carrier shops and the manufacturers shops? How are tires financed, and do you get to choose what brand and model is used? What expenses are your responsibility, and what are the penalties if you don't keep up the maintenance?
Insurance... if you're leased to a carrier under their authority, they should provide the insurance. You'll pay for it though. They should provide general auto liability, bobtail and cargo policies... if the tractor is still being financed by the owner there will be collision as well. What is your responsibility in this? What are the deductibles?
These are all questions that should be answered before you sign the contracts... and preferably before you're sitting in the leasing office with what amounts to a salesman pressuring you. Beware outfits that won't provide you with an exemplar copy of the lease before you show up for orientation... they're probably hiding something.
Before you sign, make sure you thoroughly inspect the tractor. See if you can get the ECM downloaded... that will tell you a lot about the truck. If they haven't done a PM on the truck, get an oil sample analyzed. You're looking for excessive soot, fuel dilution, and the presence of potassium
and sodium. Find out when the overhead was run last if the truck isn't new... if its been awhile (and ya have plenty of soot in the oil) its time for that, and checking if the charge air cooler is leaking. On a used truck look at the grease zerks... that'll tell you if they've been taking care of it. Any kind of odd tire wear or feathering should be checked in case it needs a three axle alignment. Make sure the brakes are in good shape. Typically these are items you will be responsible for as time goes on, so getting the carrier to take care of these things before you sign for the truck is to your benefit. Make sure they get any necessary repairs done before your first dispatch.
If they offer an APU, jump on it! First its a lot cheaper running an APU than idling a truck. APU maintenance will probably be a wash over time as well. There's a second reason for this as well. On trucks with the EPA 2007 emissions package and later you have a Diesel Particulate Filter that traps soot particles in the exhaust. Low temperature operation and idling tend to produce a lot of soot, and will play havoc with the DPF and EGR systems. That APU may keep you out of the shop and on the road... with some trucks, a lot!
So... we haven't even hooked the truck to the trailer yet, and for good reason. You have to read and understand the contracts to be successful.
